Anyone who has not realised - the reel to reel intro is a nod to the old Techmoan intro. In a previous video, someone referred to VWestlife as being a "ghetto Techmoan", so this was his perfect response!
Actually the lamp has a capacitive source, which does not introduce interference. The led board is made for 12W and is consuming much less, so it will last for years. It is much better than the others.
Philips is using high frequency SMPS - huge generator of RFI in the LW/MW/SW radio spectrum. Trisonic is only capacitive / resistive dropper / rectifier, running at 60 Hz.
Exactly, I was wondering why a comparisons were being made about RFI against a switched mode power supply and a capacitive dropper. Even very high end LED lights that use a SMPS are not going to employ common mode filters and full class Y filtering !
That bigger bulb is extremely dangerous, it is mains referenced and can kill you if you touch the cob (my heart skipped when you almost touched it cause of that cap falling). The other bulbs have tiny auto transformers which are much safer as they are stepping the voltage down, they probably have chokes to cap the current aswell were as the big one just uses resistors.
>chokes to cap the current aswell were as the big one just uses resistors. The purpose of a choke is to eliminate RF from the circuit, it does not limit the current in a circuit. The large fake rating LED bulb uses a capacitor dropper to limit the current, where a capacitor does the current limiting through reactance. Properly designed LED bulbs are no less dangerous internally. The LEDs are going to be arranged in a series string to improve efficiency, which means you'll easily see 50+ volts across them. Even if the bulb uses a transformer to isolate the high voltage DC side from the mains, doesn't mean you can't get a lethal shock from it.
Looked to me by the design of that bulb that the series string operates on a little more than 60vdc... and when one LED burns out, the whole string goes out... thus the 2 year life
Those Philips led bulbs are great utility bulbs. I've put a bunch in continuous service and they're working well years later. For a while you could get a 4 pack for $6 in VA.
I have followed you since about 2012. I don't know why but I get excited about new record player and light bulb videos. Keep up the good work. You're providing the masses with education and nostalgic joy.

Heh, I love dollar store light bulbs! Honestly, I have more fun with discovering what is really going on with these cheap led bulbs than good ones! I always enjoy these videos.
Several years ago, PSNH (the only power supplier in NH until very recently) offered a rebate program with Batteries Plus where any NH household could buy up to ten LED bulbs for $4/ea (an absolute bargain in 2012 or so). The bulbs they were offering were a new product from a startup company called "Switch Lighting." These bulbs were unlike anything on the market at the time; they had a shape very similar to traditional incandescents, featured frosted plastic globes, and were filled with liquid silicone for better cooling. I bought my entire allotment and installed them in all my fixtures (replacing all of my CFLs). These bulbs were unusually heavy, but looked great and produce a light closer to an incandescent bulb (a soft, warm, bright light). I absolutely LOVE these bulbs, and when I went to buy more, I was saddened to learn the company went bankrupt shortly after my purchase. As far as I know, some early units were prone to leakage, but mine have all been 100% trouble-free for the five years I've owned them, and one is installed in my front porch where it has never been shut off in five years.
There are "SWITCH Lighting" LED bulbs still available on Amazon: www.amazon.com/SWITCH-Lighting/b/ref=w_bl_hsx_s_hi_web_7935341011?ie=UTF8&node=7935341011
The low power factor was a clear indication the bulb used a plain boring capacitive dropper circuit to convert the 110v ac to some lower value. Most likely you have two strings of leds, I'm guessing since I count 40 leds in total, you have two strands of 20 leds on each, so the capacitive dropper takes down your voltage to around 60v DC and each led is driven at around 4.8w / 40 = 0.12w per led, at 3v forward voltage that's around 40mA of current...reasonable value.
The 375 code indicates the capacitance, which is 3.7uF The "J" means its a Tantalum capacitor. Also, since this is a very simple circuit (just a capacitor voltage reducer), it produces little to no noise (just AC noise) the other LED has a much more complex "switching regulator", which is much higher frequency than standard AC Another thing, be careful while opening the bulb! The red capacitor may still be holding some charge and can *really* shock you!
The Sylvania bulb most likely contains a switch mode power supply, which runs the LED modules at frequencies in excess of 100KHz and produces quite a lot of RF interference in the process. Given the lack of banding, it would appear to have plenty of input filtering. The Trisonic bulb contains a capacitive dropper (SMD diodes form the bridge rectifier) with inadequate input filtering, which results in a significant amount of AC ripple on the output. This is what produces the banding effect. Incidentally, inadequate input filtering is also quite a common characteristic of cheap electronically ballasted fluorescent lamps and is why many people find them to be rather headache inducing.

I think Sylvania actually built an American LED factory this year. They'd probably be the first and only company to do so. I've seen others that say "assembled in USA", but don't recall if they were also Sylvania
Diagram seems simple enough, if anyone is interested that 375/3.7uF capacitor works as capacitive dropper, the 334/330k resistor is for bypassing any stored charge in it. The LEDs are probably on series and the two 330/33R resistors are in parallel to get 16.5R in series with those LEDs to limit the current. Other capacitor is across the LED string to make the lamp less flickery. That's also why it doesn't interfere with AM.
Planned obsolescence begin with lightbulbs and its now caught up with LEDs (btw, Philips was the company that created planned obsolescence in the first place). I bought a bunch three years ago, only had one go bad. New ones probably won't last a year.

Had one of these cheap Chinese LED bulbs give me a shock before, it was one of the ones with the exposed heatsink and when it died I put my hand on it to swap it out and got zapped off 240V mains. You forget how badly 240v hurts until it happens again.
I have been replacing the bulbs where I live with the dollar tree LED lights. Some are 2+ years old and are still working fine. The color temperature is nice too.
I love your videos... Have been a subscriber for many years. You make the most mundane subjects very interesting and your videos have a nice.relaxing effect on me. You along with LGR, the 8 bit guy uxwbill and techmoan are the channels I can't gen enough of. Just wanted you to know!!!
I love the reel to reel intro of this video, much better quality than the trisonical light bulb! You should upload the contents of the tape if you can.
I kinda like the no radio interference feature and the fact it uses half the advertised energy usage! A suggested jingle, "You get less for your money with Trisonic!"
I recommend you review the Cree brand LED's I bought mine when Cree first started releasing them to the market a few years ago. Mine are first generation Cree LED's and are heavy cast aluminum with large heat sink cast into them. They use actual glass bulbs with a rubber membrane over the glass to diffuse the light. 3+ years later they are going strong. One of them has been hanging exposed in a broken outdoor light fixture and is unphased by weather exposure or even cold. They were quite expensive when I bought mine and I'm not sure what they cost now but I know they are much cheaper now. I would be interested to know if the build quality is still as good as the first generation Cree LED. The light output is also fantastic can't tell any difference from incandescent at all
10:14 375 means 37 and then 5 zeroes on the end (in pF) - so 3.7uF. Rating is ofc 400V. So it seems like a simple capacitive dropper circuit with no mains isolation. 334 resistors are 33 and then 4 zeroes = 330k Ohms. Since there are two of them it looks like they are the discharge resistors across those two caps. The 330 resistors (33 and 0 zeroes = 33 ohms) are more than likely to do with the LEDs.
Hi Westlife, a big fan of your videos. I just have one question. The other day I was cleaning up my dad's room and came across the same Akai reel to reel you show on this video. I powered it up and it seems to work fine although I do not have any tape to go in there. However, when I found this unit, the PLAY was engaged and due to the time it has been stopped in the play more, there is a small grove caved into the rubber pinch roller from the capstan stick. Due to that, when I hit the play, its spinning with that grove makes the pinch roller jump up and down making it not an even play back. Is there a place where I can buy that pinch roller wheel? I would like to fix this up and get some tapes to go with it. I've always wanted to own a reel to reel even though it was not my era when growing up. Can you help me out to get a new rubber roller or any ideas to fix it? Look forward to your reply. Thank you so much for great informative videos, I really enjoy them.
Got a Trisonic 6500k, 5 watt, 40w Equivalent bulb on Feb 2017 and it died Aug 15 2019 and started SMOKING! It was indoors in a desk lamp. LED's should not go up in smoke when they die right ???
the reason for the bulb to run at 60 hz is because the dropper circuit usually is a capacitor/resistor instead of a full switching power supply. the led bulbs are usually made up of several led chips wired in series so they can run from 50 volts dc and sometimes there are 2 or 3 parallel strings of led chips at 4 watts that is very good power usage for an led. the fact that the dome comes off so easy is not safe. you should only use the trisonic bulb in a place where it is out of reach of children and even adults so you dont come in contact with the exposed connections
With those open vents I hope nobody uses these bulbs outdoors. I bet that bulb was for stored for years and the cheap glue gun glue that held it all together has dried out.
One thing about the color temperature of light is that the higher the number means that the light is less bright in terms of the amount of cool white (aka daylight type white) light it outputs. 5000K will be brighter than 6000K, and the higher the number the light appears more with a blueish to a purplish tent to it.
I have a few incandescent bulbs kicking around. I have some CFL and LED bulbs installed. Some LED fixtures that have lights built-in and can't even take a bulb have terrible 60hz flicker and I hate that. LEDs and AC power do not get along.
LED bulbs can work really great if they actually add in a smoothing capacitor to the full bridge rectifier. Then you'll get a great smooth look at low energy costs. Saves on those electricity bills!
Wow those red caps are hot now on the audiophile market. People paying 800-1000 dollars for those Trisonics to grab those unique run of capacitors. They are hard to find now.
How would these compare to the Cree LEDs? I know I've been brought up by their TV commercials, and I have a lot of bulbs in this condo replaced with Cree LEDs, and I've had a couple that almost burned out right out of the box. Most of them DID work, however, and very strongly, too.
yes they do more than a cap dropper and rectify, so interference is going to happen, but for normal useage it wont affect anything, unless you listen to am 1ft away from a lightbulb
Ha! - I called this site the ghetto Techmoan last time, so he added the reel to reel shot at the end with the ghetto Akai deck missing some parts - This guy has a great sense of humor! - awesome!
I have become very picky when it comes to LED bulbs. There are some SMD LEDs that are really good but i prefer these filament LEDs even more because of their 360° illumination range, just like their incandescent originals. However they often seem to flicker a lot in the lower Watt replacement range, like for 40 watts. While the higher ones like 60 Watt replacement are totally fine and flicker free. Pulse-width Modulation LEDs are the worst when it comes to flickering.
There are one dollar Sunbeam (which isn't an unknown or even really obscure brand) LEDs at Dollar Tree. I'd be really interested to hear your opinions on those.
The orange capacitor is used as current limiter ; the value should be about 1 uF, 400 Volt. The AC 120 volt goes thru it, then to the diode bridge and finally the electrolytic capacitor reduce is regulating the DC to decrease flickering. All the LED are connected in series ; 3 volt each adding to 90 volt if there is 30 LED. One resistor is probably in parallel to the electrolytic capacitor and is there to discharge it when the lamp is powered off. Simple circuit, inefficient but creating no EMF on the AM radio. Still no as bad as if a resistor would have been used as current limiting. The capacitor can return to the grid part on the energy instead of total waste as heat like resistors do. Since most loads in a typical house are inductive, this lamp may counter balance such load and end-up improving the poor power factor.
I have a Trisonic 16 foot Tape Measure that I also purchased at a Dollar Store 😀. I bought it in Jersey City 😀. It doesn't seem to have any defects. At least not yet. I guess Trisonic sells it's products to Dollar Stores 😀. Interesting videos as always 😀.
Good way to mess up your sleeping cycle... Humans have evolves around campfires and candles in the evening, not bright light with a lot of blue in it, it has been proven to mess up your melatonin production no matter how high-tech and cool it might appear to you.
That trisonic should be a 40 watt equivalent. Daylight bulb, plus every 40 watt equivalent led bulb I have seen seems brighter than a 40 watt incandescent. Plastic base with air vents for cooling instead of a metal heatsink base probably also will cause lower life of the bulb. Truthfully I kinda want one of those trisonic, just to compare to other led bulbs in my table lamp, and maybe use it there just to see how long it actually lasts. The first cfl bulb I bought, before many people even knew about them, was only rated for 3 years I believe at 4 hours a day, but I got 4 years out of it at many more hours a day usage. Maybe the easily removable dome on the trisonic is so it can run and let heat escape and thus increasing it's life.
375J would be 3.7uF, looks like the typical capacitor dropper circuit I've seen so many times (mainly in Big Clive's videos). You have to remember they're comparing to what would be a 100w bulb in Chinese watts, witch are a lot smaller than normal watts! I thought I was accidentally watching one of my videos at the start as I have a Reel to Reel a lot like that. Bet THAT didn't come from the dollar store!
Actually, if you calculate the 'real usage' with the power-factor you get about 12 Wattsssss... about 3 times about 4 = 12 (invert the power-factor). So it will be 'using' 12 Watts and if you put some of them parallel on for example an inverter you will notice that in the spikes they use. Actually it can be fun to use these kind of lights on a cheap inverter because the average voltage will be pretty high on the LED's and probably will stop them working in a few hours. (effect of not real sinus). Like with a lot of chineese stuff: if the hotglue is not working anymore, just add some more to re-attach. Nice review.
I like IKEA's TRÅDFRI series. Means I can have daylight when I need it, 'normal' light and a very warm light when I wan that. And the price is not terrible. Oh and now you can get them with multicolor options, "almost" a replacement for Phillips Hue.
VWestlife, I have a request for a video. Would you be interested in doing one on turntable cartridges and styli? For instance, can an expensive stylus make a cheap turntable sound better, gains and losses with different types, and is it actually worth spending the money to upgrade.
LED lights last forever. I have one on my back porch from 2013. It is the twisted kind. The bulbs I have from 2019 look like an old glass bulb. They all still work 5 years later also.
Hey VWestlife. Something I've discovered is that China is also where things like all new flat screen TV's, receivers, headphones, speakers, & all other new electronics are being made. What do you think about that? :)
+makomk +PileOfEmptyTapes You can also count that one named Vestel. Even the bigger brands have that bad habit of having their lower end models manufactured by Vestel. And those lower end models end up as the ones supermarkets try to sell off, making you think that you made a good deal. Whereas you're just buying a crappy TV in the end (ah... those Panasonic so-called 4K ones with firmware problems and unexpected random shut-off on HDMI sources...). I bet even Chinese sets made by TCL are better.
it is a good thing, but it is not equivalent to a 100 watt bulb as they claim. Since most consumers buy bulbs according to it's power rather than it's luminence, it is considered false advertisement.
it probably is 12w if you take into account power factor 😉 personally in one way i prefer the cheaper ones that use capacitive droppers as less parts to fail, and they dont seem to run the led chips as hard, they use quite a few leds, the ones with switching regulators in seem to use less leds, but higher power ones, and drive them well hard,
i recently opened up 2 faulty led bulbs, one capacitive dropper type, one with little switch mode, the switch mode ones leds were obviously fried, darkened, cracked phosphor,, no signs of burning on the capacitive one but still slight cracking of the phosphor, this one does work for a bit then intermittently flicks off for a fraction of a second, the switch mode one was like a disco strobe!!
Don't be such a downer on Trisonic, their tool-less teardown system is state of the art!
Trisonic sounds like some super badass synthesizer you'd buy in the 80s.
Or a cheap VHS tape brand
Or a cool album
In the 80s, those cheapo blank audio cassettes used to have names like Kingsonic, Bonsonic and Melsonic. One thing was for sure - they were all cack!
Not making this up, But I think that "brand" WAS used on cheap VHS tapes. I also think I was batteries with this "brand".

Is it really more dangerous than an incadecant bulb? Or just worse that quality LED bulbs?
I love the reel to reel intro of this video, much better quality than the trisonical light bulb! You should upload the contents of the tape if you can.
The 375J marking is probably 3.7uF. That's an unusual value.
I kinda like the no radio interference feature and the fact it uses half the advertised energy usage! A suggested jingle, "You get less for your money with Trisonic!"
Which is better SMPS power supply or capacitive dropper
I recommend you review the Cree brand LED's I bought mine when Cree first started releasing them to the market a few years ago. Mine are first generation Cree LED's and are heavy cast aluminum with large heat sink cast into them. They use actual glass bulbs with a rubber membrane over the glass to diffuse the light. 3+ years later they are going strong. One of them has been hanging exposed in a broken outdoor light fixture and is unphased by weather exposure or even cold. They were quite expensive when I bought mine and I'm not sure what they cost now but I know they are much cheaper now. I would be interested to know if the build quality is still as good as the first generation Cree LED. The light output is also fantastic can't tell any difference from incandescent at all
Its interesting how 60Hz LED bulbs shot by a rolling shutter creates an effect very similar to how 60Hz AC hum manifests in analog NTSC signals
I didn't see any CE or UL markings on the package.
10:14 375 means 37 and then 5 zeroes on the end (in pF) - so 3.7uF. Rating is ofc 400V.
So it seems like a simple capacitive dropper circuit with no mains isolation.
334 resistors are 33 and then 4 zeroes = 330k Ohms. Since there are two of them it looks like they are the discharge resistors across those two caps. The 330 resistors (33 and 0 zeroes = 33 ohms) are more than likely to do with the LEDs.
Nothing good comes in blister packing.

Hi Westlife, a big fan of your videos. I just have one question. The other day I was cleaning up my dad's room and came across the same Akai reel to reel you show on this video. I powered it up and it seems to work fine although I do not have any tape to go in there. However, when I found this unit, the PLAY was engaged and due to the time it has been stopped in the play more, there is a small grove caved into the rubber pinch roller from the capstan stick. Due to that, when I hit the play, its spinning with that grove makes the pinch roller jump up and down making it not an even play back. Is there a place where I can buy that pinch roller wheel? I would like to fix this up and get some tapes to go with it. I've always wanted to own a reel to reel even though it was not my era when growing up. Can you help me out to get a new rubber roller or any ideas to fix it? Look forward to your reply. Thank you so much for great informative videos, I really enjoy them.

Got a Trisonic 6500k, 5 watt, 40w Equivalent bulb on Feb 2017
and it died Aug 15 2019 and started SMOKING! It was indoors
in a desk lamp. LED's should not go up in smoke when they die right ???
Perhaps you should have tried the meter in VA mode; given the power factor, it might have read close to 12VA.
the reason for the bulb to run at 60 hz is because the dropper circuit usually is a capacitor/resistor instead of a full switching power supply.
the led bulbs are usually made up of several led chips wired in series so they can run from 50 volts dc and sometimes there are 2 or 3 parallel strings of led chips
at 4 watts that is very good power usage for an led.
the fact that the dome comes off so easy is not safe.
you should only use the trisonic bulb in a place where it is out of reach of children and even adults so you dont come in contact with the exposed connections
10:09 375J is 3.7 micro Farad. The third digit is a multiplier. On 375J, five means five zeros and the value is 3700000 pico Farad.
What model of R2R recorder is that? I don't think I've ever seen one with Dolby NR!
Akai 4000DB.
That Trisonic doesn't have a heatsinc on the LED's either. 2 years is a little generous...!
Big aluminium plate ... works like a heatsinc. Try to solder on these boards ... :-(
With those open vents I hope nobody uses these bulbs outdoors. I bet that bulb was for stored for years and the cheap glue gun glue that held it all together has dried out.
i think the interference is the "higher than 60Hz" thing. the sylvania one runs at some frequency that interferes with the radio.
I'm not a fan of all the LED style Christmas lights I've seen this year. They seem to have a very rapid flickering which I find unpleasant.
They are just resistive dropper circuits, and light at the peak of the voltage waveform.
"Tranquility is beauty. Equanimity is joy. Soi soi soi." I need to start quoting that.
One thing about the color temperature of light is that the higher the number means that the light is less bright in terms of the amount of cool white (aka daylight type white) light it outputs. 5000K will be brighter than 6000K, and the higher the number the light appears more with a blueish to a purplish tent to it.
does it have a FULL BREEDGE RECTIFIAH
Electro Boom ?
I have a few incandescent bulbs kicking around. I have some CFL and LED bulbs installed. Some LED fixtures that have lights built-in and can't even take a bulb have terrible 60hz flicker and I hate that. LEDs and AC power do not get along.
Get better LEDs that arent just doing half wave rectification. You should try LED filaments bulbs too.
LED bulbs can work really great if they actually add in a smoothing capacitor to the full bridge rectifier. Then you'll get a great smooth look at low energy costs. Saves on those electricity bills!
Michael O I have a vintage looking LED filament bulb and rhe flicker is horrible. The LEDs are hooked up in series with the mains.
Wow those red caps are hot now on the audiophile market. People paying 800-1000 dollars for those Trisonics to grab those unique run of capacitors. They are hard to find now.
How would these compare to the Cree LEDs? I know I've been brought up by their TV commercials, and I have a lot of bulbs in this condo replaced with Cree LEDs, and I've had a couple that almost burned out right out of the box. Most of them DID work, however, and very strongly, too.
The LED hi-hats in my new place manage to destroy VHF TV reception when they are on, but what do you expect from Depot special brand fixtures?
How many incandescent bulbs do you have stocked up?
The Trisonic package says on the back "contains" mercury. I thought LED bulbs did not contain mercury.
I think the circuitry to prevent flickering inside more expensive bulbs is what creates radio interference
yes they do more than a cap dropper and rectify, so interference is going to happen, but for normal useage it wont affect anything, unless you listen to am 1ft away from a lightbulb
How does the light cause interference with the radio
Ha! - I called this site the ghetto Techmoan last time, so he added the reel to reel shot at the end with the ghetto Akai deck missing some parts - This guy has a great sense of humor! - awesome!
I have become very picky when it comes to LED bulbs. There are some SMD LEDs that are really good but i prefer these filament LEDs even more because of their 360° illumination range, just like their incandescent originals. However they often seem to flicker a lot in the lower Watt replacement range, like for 40 watts. While the higher ones like 60 Watt replacement are totally fine and flicker free. Pulse-width Modulation LEDs are the worst when it comes to flickering.
I still have no idea what your channel is about but I like it
Equanimity is joy.
Soi soi soi
There are one dollar Sunbeam (which isn't an unknown or even really obscure brand) LEDs at Dollar Tree. I'd be really interested to hear your opinions on those.
I heard KMOX at 7:18 love your AM SCAN
The orange capacitor is used as current limiter ; the value should be about 1 uF, 400 Volt. The AC 120 volt goes thru it, then to the diode bridge and finally the electrolytic capacitor reduce is regulating the DC to decrease flickering. All the LED are connected in series ; 3 volt each adding to 90 volt if there is 30 LED. One resistor is probably in parallel to the electrolytic capacitor and is there to discharge it when the lamp is powered off.
Simple circuit, inefficient but creating no EMF on the AM radio. Still no as bad as if a resistor would have been used as current limiting. The capacitor can return to the grid part on the energy instead of total waste as heat like resistors do. Since most loads in a typical house are inductive, this lamp may counter balance such load and end-up improving the poor power factor.
If i remember correctly the rating on 10:13 is 3.7UF its 37 and five 0 so it would be 3700000 pico farad which equals 3.7 UF or MFD
I have a Trisonic 16 foot Tape Measure that I also purchased at a Dollar Store 😀. I bought it in Jersey City 😀. It doesn't seem to have any defects. At least not yet. I guess Trisonic sells it's products to Dollar Stores 😀. Interesting videos as always 😀.
I prefer Daylight bulbs over soft white. Even better is 8000K "Skywhite" but they don't make LEDs in that color.
I prefer daylight for overhead and a lower color temperature for lamps.
Good way to mess up your sleeping cycle...
Humans have evolves around campfires and candles in the evening, not bright light with a lot of blue in it, it has been proven to mess up your melatonin production no matter how high-tech and cool it might appear to you.
At 5:46 it looks like i'm staring at a planet.
The Bulb is made for crawl spaces where the holes on the case of the bulb point up to vent the heat,what such design :-D
Where did you get that outlet extension?
VWestlife
That open reel taperecorder reminded me of an Akai GX-4000 i once had, but mine didn't have dolby, is that an after-market upgrade?
Ah, i think i found the answer myself: it appears it is a model 4000DB, is that correct?
Yes.
8:28 OMG, that was so close, please be careful 🙏
Thanks for the content
That trisonic should be a 40 watt equivalent. Daylight bulb, plus every 40 watt equivalent led bulb I have seen seems brighter than a 40 watt incandescent. Plastic base with air vents for cooling instead of a metal heatsink base probably also will cause lower life of the bulb. Truthfully I kinda want one of those trisonic, just to compare to other led bulbs in my table lamp, and maybe use it there just to see how long it actually lasts. The first cfl bulb I bought, before many people even knew about them, was only rated for 3 years I believe at 4 hours a day, but I got 4 years out of it at many more hours a day usage. Maybe the easily removable dome on the trisonic is so it can run and let heat escape and thus increasing it's life.
375J would be 3.7uF, looks like the typical capacitor dropper circuit I've seen so many times (mainly in Big Clive's videos). You have to remember they're comparing to what would be a 100w bulb in Chinese watts, witch are a lot smaller than normal watts! I thought I was accidentally watching one of my videos at the start as I have a Reel to Reel a lot like that. Bet THAT didn't come from the dollar store!
Actually, if you calculate the 'real usage' with the power-factor you get about 12 Wattsssss... about 3 times about 4 = 12 (invert the power-factor). So it will be 'using' 12 Watts and if you put some of them parallel on for example an inverter you will notice that in the spikes they use. Actually it can be fun to use these kind of lights on a cheap inverter because the average voltage will be pretty high on the LED's and probably will stop them working in a few hours. (effect of not real sinus).
Like with a lot of chineese stuff: if the hotglue is not working anymore, just add some more to re-attach.
Nice review.
I like IKEA's TRÅDFRI series. Means I can have daylight when I need it, 'normal' light and a very warm light when I wan that. And the price is not terrible. Oh and now you can get them with multicolor options, "almost" a replacement for Phillips Hue.
VWestlife, I have a request for a video. Would you be interested in doing one on turntable cartridges and styli? For instance, can an expensive stylus make a cheap turntable sound better, gains and losses with different types, and is it actually worth spending the money to upgrade.
Yoda Gates: may Microsoft Sam be with you.~
LED lights last forever. I have one on my back porch from 2013. It is the twisted kind. The bulbs I have from 2019 look like an old glass bulb. They all still work 5 years later also.
When he goes to the dollar store, you know something magical is going to happen
LOL, there's a reason that was sitting in a Dollar or thrift Store... But I love your videos! Keep it going!
After it burns out, you can play badminton with it! 😃😩
Um, sir, you seemed to be a little perturbed while using those scissors
Wow $3,99 is expensive? Here in Brazil they cost between 20-120 dollars...
Hey VWestlife.
Something I've discovered is that China is also where things like all new flat screen TV's, receivers, headphones, speakers, & all other new electronics are being made. What do you think about that? :)
Not all, but most.
Yeah, a lot of the lower end flat screen TVs sold in Europe are made in Turkey for some reason.
That reason would be BEKO, a large manufacturer of appliances and electronics of all kinds.
PileOfEmptyTapes I think that compost in Turkey id's a subsidiary of a Chinese company
+makomk +PileOfEmptyTapes You can also count that one named Vestel. Even the bigger brands have that bad habit of having their lower end models manufactured by Vestel. And those lower end models end up as the ones supermarkets try to sell off, making you think that you made a good deal. Whereas you're just buying a crappy TV in the end (ah... those Panasonic so-called 4K ones with firmware problems and unexpected random shut-off on HDMI sources...). I bet even Chinese sets made by TCL are better.
my god, the soisoisoi broke me
What is a power factor? Also isnt it a good thing that it uses less watts than expected without lowering the lumens?
Let me Google that for you: en.wikipedia.org/wiki/Power_factor
but what about my second question? am I expected to google that myself?
Yes
it is a good thing, but it is not equivalent to a 100 watt bulb as they claim. Since most consumers buy bulbs according to it's power rather than it's luminence, it is considered false advertisement.
it probably is 12w if you take into account power factor 😉 personally in one way i prefer the cheaper ones that use capacitive droppers as less parts to fail, and they dont seem to run the led chips as hard, they use quite a few leds, the ones with switching regulators in seem to use less leds, but higher power ones, and drive them well hard,
i recently opened up 2 faulty led bulbs, one capacitive dropper type, one with little switch mode, the switch mode ones leds were obviously fried, darkened, cracked phosphor,, no signs of burning on the capacitive one but still slight cracking of the phosphor, this one does work for a bit then intermittently flicks off for a fraction of a second, the switch mode one was like a disco strobe!!
