I wanted to say that I really think having the lighting fixed on a set value before you begin is actually really nice, especially when you are working with lights. I really like that the whole scene doesn't change brightness whenever the lighting changes, I think it's an improvement.
+BenjaminGoose lithium + led is a good combo, no heat, i have the same/similar light, runs 3 hours plenty of light to do jobs by without needing it in your face either, no like the old dim torch days! i used to carry one of them old gas fitters rubber torches, bloody useless they were!
ooh, that "gaslight white" sounds nice, I have an Aladdin mantle lamp that when I use a thorium mantle on it, it has a nice greenish white light, I like that colour of light... :) I think the black background doesn't do well, your older vids with the brown (bare MDF?) colour worked nicely...
It seems like the rule of thumb for Chinese lights is, if you want 10 watt, but a 20 watt version. That, or assuming that the LED is in fact 10w (with this one running at 8w including the driver), find a source of properly rated drivers and upgrade them to meet the spec. (but while you are at it, you may as well but a decent LED in there too)
Try testing the 'mystery box' with both polarities of the meter leads(switch them around). If it reads the same in both directions,then it's not a diode,and is less likely to contain any solid-state circuitry/silicon junctions..at least directly between those leads You could also measure the voltage drop across it,while running it at various supply voltages/currents,to see if the drop is fairly constant,or not. Or just go 'full gorilla' on it with a hammer,and get a look inside. :)
I went and bought a different version of this that has 20 separate leds on a PC board, I think they might be 5050's but not 100% sure. It came with 3 removable 18650 batteries that are very light so I doubt they are any good. I popped some of my good batteries in it and I love it. It's frame is also a bit different, it's made from bent flat stock and then that is rubber dipped (quite nice actually) but it's the same size and wattage as yours. I don't know why but I prefer the PCB mounted led's to COB leds. I don't have a good reason for this but I just do.
+sublimationman I think the loose LEDs are actually a better option than the higher wattage LEDs like 20W upwards. But the little 10W arrays seem to be pretty rugged.
Did you know t hat we use yellow lights here in Australia as bugs are not attracted to them and toads since we ended up introducing them to kill cane beatles but they now are a noxious species.
I wonder what the voltage is from the car adapter? I work on a sewerage treatment works and some of the mechanical guys use these, the paces they put these lights through they are very reliable and the battery's on them see to last quite well even after being over a year old and left on charge for hours on end. Very nice lights and they provide an excellent work light!
The batteries that came in my 15 watt rated work light were only 1300 mah each and they looked used. One of them rattles when you shake it. I also have the same protection board and it blew when I put one more battery in it to increase the run time. It couldn't handle the load of one really good cell and two terrible ones. So I replaced all with new 2800 mah Samsung 18650's and put in an 3 amp protection board. It now works really well. Now as far as the power bank part of my light. It is crap. I plug my phone in to charge and it can only handle .48 MA and the voltage is 4.85, so the boost circuit is junk as well. So I will replace those as well with the 1 amp charge boards. So after another $20 in parts it is a good light, total cost $47.00 US and it functions well.
You should get a cheap 10w flashlight (the ones with the lithium cell) and check how powerful they really are. Couldnt find anything about those lights on the web.
I couldn't help but laugh at your comment that "red doesn't always mean positive in China". I can add that they sometimes don't know that internal screws holds their devices together either. I have received more than one item with transformers banging around inside. At 27.99 USD, these lights are pricey considering their components and construction. However, with some additions of more LEDs and a larger capacity battery pack, one could make a real flood out of this.
also when plugging in 12v the battery circuit would disconnect the batteries and the voltage would be at 12v with no load. now you can guess what would happen if somebody would turn the led on with 12v at the 8,4v rail...
+Steven Birch It will be destructive due to the hard nature of the potting compound. But once I've finished the lithium capacity tests it will be thoroughly destroyed.
18:37 - BigClive™ definitely needs to get a mountable paper towel dispenser for his bench considering the amount of times he gets stuff like this on his hands and then has nothing to wipe them on. :)
I dont see why that led light is designed that way because the manufacturers would only have to use one charge circuit if they built it into the light instead of using two seperate charge curcuit for the mains charger and the in car charger, the chinese can be so thick sometimes.
yeah they should have used a different connector fofr the charger, I could see bad things happening to that battery if one was to use the wrong charger, like a simple 12volt wall wart for example.
Clive from your findings is this info correct (I never trust the marketing from the Chinese)? Wattage: 10 W | Color Temperature: Cool White(6000-6500K) | Brightness: 500 Lumens Lens Cover Material: Toughened Glass | Input Voltage: AC100-240V | Degree Beam Output: 120 Degrees | 10w LED bulb is as bright as 100w halogen bulbs.
Hey, Clive. I've been watching your videos for a short while now and I have to brag that I watch every video you put out and I'm never disappointed. I learn so much and I envy your ability to break the circuits down to the theory. I'm curious, what is your typical viewer? Male? Female? Age? Keep up the good work regardless!
+bigclivedotcom Well, I'm British - so I must be in the minority then. I have pretty much viewed all your videos and you're often informative, sometimes quite amusing and always entertaining! I must say that this time I found most of the imagery much too dark. I know people keep complaining that certain objects become over exposed, but if you're going to lock off the exposure you'll need to adjust it to compensate for darker objects. I think perhaps black was not the best choice of colour for your background - maybe try using some coloured paper to see what works best rather than commit to a specific colour change and see what sort of feedback you get?
+Gavin corbett This is the listing I bought it from:- www.ebay.co.uk/itm/121784834923 Although a search for rechargeable 10W work light will bring up lots of listings.
+bigclivedotcom Thank you Clive :) How 'bout a tear down on an old school VCR or a DVD player, always been curious as to how those little boxes of magic work. Cheers for now and thanks for all the late night entertainment, it's always great waiting to see what the nights instalment will be :)
+zx8401ztv Yeah, at first I thought it was a voltage booster for a normal 10W LED, then I thought it might just be an active current regulator. But as the intensity went down so obviously with voltage I would say it's just a resistor in there. Perhaps earlier versions did use a 10W LED and booster, then when they switched to the custom LED they just used a resistor instead.
+bigclivedotcom Im not fully with the use of leds for lighting yet, leds allways seem directional and people get conned by there apparent brightness, any bulb would look bright if the light was all channeled in one direction. But im still amazed how good they are, to me leds are just power indicators on vcr's and such, yep im stuck in the past lol :-D
+zx8401ztv LEDs aren't popular for the brightness, it's how little power they draw that makes them popular. there isn't an led 240v globe I'm aware of that could match an old 150watt bulb. but you can run a fuckload of them for less power
+Winsucker If the chargers do put out 1A then the charging time will be closer to 2 hours, and the two versions I've tested so far clocked in at four hours for one and 3 hours 15 minutes for the other.
Hello, I've sent you a private message but here's a link to one that actually has the driver circuit inside from amazon: www.amazon.com/gp/product/B00XQSL9Q2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Maybe you could tear into it and do a little review on it yourself if you're interested. I uploaded a picture of some of the circuitry via photobucket that is in your PM. I'm not sure that it'll be the full 10 watts but there's more of a chance with this one I believe and maybe the possibilty of modding the driver. I actually have this one from this seller and can confirm that it has a driver.
I liked the brown work top best. Every mark and burn on it represents a fun filled incident and video.
I wanted to say that I really think having the lighting fixed on a set value before you begin is actually really nice, especially when you are working with lights. I really like that the whole scene doesn't change brightness whenever the lighting changes, I think it's an improvement.

I believe you meant it the other way round, didn't you?

i ordered the 30w green and will be doing an unboxing vid once i get it
Gas light was a very good description. I love gas lights :D Bet they'd be no good for you tho, they'd keep the house far too warm for you
Maybe try a mid-gray background?
You need an X-ray machine! I had good fun X-raying iPods of classmates at school.
and by the way, those are 2200mah 18650 cells, I have 4 of them exact equivalents. They use them in power banks too.
The batteries that came in my 15 watt rated work light were only 1300 mah each and they looked used. One of them rattles when you shake it.

Hey Clive,
try a grey table color. :D
Selling them in Maplins for 20 quid. They do work well
are you going to investigate the cigarette lighter charger
also when plugging in 12v the battery circuit would disconnect the batteries and the voltage would be at 12v with no load. now you can guess what would happen if somebody would turn the led on with 12v at the 8,4v rail...
I'm surprised that you managed to resist the temptation to hack the potted module apart to confirm its contents, however fiddly!
+Steven Birch It will be destructive due to the hard nature of the potting compound. But once I've finished the lithium capacity tests it will be thoroughly destroyed.
+bigclivedotcom Oh good, I thought you were slipping for a moment.
A handy little work light..
will it handle 4h? doubt it. maybe 2h with those 18650s.
Hmm so looks like the suppliers spec of 8800mAh @ 7.4V is somewhat optimistic bearing in mind the cells you found.
+Steven Birch Yes. I'll be testing them to see if they are even what's on the label.
You need a small x-ray machine, that is what im getting out of this. :)

does the cigarette lighter charger have a charge controller in it too?
Yes it does.
What about the 12 volt car charger? Won't that output 12 volts?

You need to invest in/ build an Xray machine! Then we can find out whats in the box with out total destruction.
