I have had great luck with CFLs. And LED. The Straight PL types from Philips invention started the CFL revolution. Straight are slightly more efficient, bending the glass causes some of the phosphors to not perform to optimum, by a tiny amount, but it certainly shrunk the lamp to fit everywhere.
We had a major change in our electric company pricing structure years ago. My one bedroom apartment electric bill went from around $22 dollars a month to nearly $50 bucks, with no change in my consumption. As I grappled with trying to make sense of it all, I made the decision to switch out all the 40 to 100 watt light bulbs I used with lower wattage CFL equivalents. Yep, it was a few bucks, but the lower bill, with the new pricing, I received from that point on was worth it. These bulbs do have an impact on your usage.
I'll stick with HID's, nice and bright. Just need to make sure I remember to turn off the outside one otherwise I'll end up with a Boeing 747 parked in my front room.
Sidieblooming - A fluorescent light has to have mercury to work. It is the mercury in vapor form that strikes the phosphor coating of the lamp that makes it glow and give off light. The guy that invented the CFL at GE, tired a number of different ways to make them work with other elements and some of them did give off light, but they never reached the same level of lumen per watt that the standard mercury filled CFL makes.
I am not sure if CFL's are going out of style. I still have incandescent bulbs in my house. But when they burn out I am replacing them with CFL's. They seem to last forever. But when they do burn out I dispose of them by going to Home Depot. It's the right thing to do.
There are testing laboratories which carry out a huge variety of test conditions for all kinds of light sources we see everyday to find out how they behave. They use a halogen sniffer, the same one garages use to detect halogen leaks from a car engine, and that thing started screaming when it was held above the CFL lamp. I've seen it on a serious TV documentary about the light bulb cartel founded in 1925-1947-Today. That's why light bulbs don't live more than 2000 pre-designed hours!
SLAVE LABOR Please TCP prove no Chinese people who are incarcerated in China have no hands on, no involvement in the production of ANY (you hear me) ANY, not one breath spent by anyone in prison working on any part of your beautiful product. Bravo. Lead on your own. Build Peace live better everyday
In a documentary someone held a halogen detector from a car workshop to detect oil fume leaks aobout 20cm over a CFL, and this thing was chanting in a high tone. A colleague of the company I work for told me that he noticed a pretty bad smell after replacing light bulbs by CFL's.
they are more efficient but they only give a narrow range of the spectrum. I like the simple incandescent light bulbs better because their light is more natural and warm with no flicker.
I bought e149698 bulbs at home depot about 7 years ago, they are all automatically controlled to come on every day at sunset, and turn off 2.5 hours later. In addition to this, there are motion sensors that have the lights come on for 4 min intervals, and this occurs about 3 times every night. With the short cycling included, I would estimate any one bulb has about 7500 hours on it. I have never had to replace any of these type.
The CFLs that light up instantly soon go black at the ends and fail after a short life. The material that coats the cathodes (filaments) gets ripped away and coats the inside of the tube black. The ones that start dull and take 1-2 seconds to come up to full brightness last WAY longer. Their filaments get to full heat before much voltage is applied to the ends of the tube. We set up a 10 watt conventional tube on an electronic ballast using this method and got 300,000 starts before we gave up.
I know that lead free solder is banned in medical electronics and in aerospace electronics, they have to use good old 60:40 or something similar in those. One other problem it often has is the formation of tin whiskers apparently, the lead puts a stop to it. It's no big seal using lead free solder on a copper water line, even though the old lead stuff never really harmed anyone there either, but the last thing you want is a piece of navigation gear shorting out from tin whiskers at 40,000 feet.
You won't believe how Subjective the members of the RUclips are. I am an engineer and I can say this. CFLs are good idea at some places but not at the other. It’s excellent idea mainly at places where it’s hot and Air Conditioners are used all the time. In this case, if the package says each bulb will save you $50 in electricity. It will actually save you more than $150 in electricity due to the reduced cooling cost from your AC.
Like I said, once I heard them mention in the video that they use RoHS compliant lead free solder the ballast circuit board I knew that they were crap, its the same reason a lot of TVs and other electronics won't last more then five years before failing. One CFL I have had some luck with are the Phillips branded ones for some reason, maybe they make their own? The UL number on those is E 130360 Another is a Syvania brand one with a UL number of E 137657.
dummies who pay $35USD for 6 light bulbs that really suck. and much more mercury, and other poisons, in seafood than in CFL lights. LEDs are a joke for real lighting!
The circuit board does not contain any hazordous materials because it's contained in the bulb.Wear a dust mask if you break one and wash your hands after.
MASSIVELY laborious process. It's kind of amazing to see how much money was dumped into this highly complex and intricate technique which STILL clearly needed huge amounts of manual tweaking at every step, when high volume LED bulb manufacture was literally right around the corner making it all obsolete within I'd say probably mere months of this video's upload.
the incandescent light bulb works on the basis that the filament is bombarded by electrons which vibrate it and thus cause it to emit light. However it releases more heat then light just because heat itself is vibration of the atoms. no matter wat alloy u use more heat will be released
The 1990's called and wanted all CFL back. LED is the future. CFL is next in line to be phased out by EU after Class C or lower Halogen Bulbs. Special Halogen Bulbs like G4 will be available after the ban on Halogen Class C or lower.
I replied to the other guy's comment already (he was wrong), but I seriously doubt broken incandescent bulbs emit tungsten - it's a metal with a famously high melting point (3,422 degrees Celsius) and solid at room temperature (unlike mercury). To get gaseous tungsten you'd have to heat it to the boiling point, which is 5,555 deg. C (normal lightbulb operating temperature is usually about 3000 deg. C)
@stickedU You're joking, right? It takes more energy to produce a CFL than it does to make one incandescent light bulb. And there are far less hazardous materials used.
You say your LED bulbs are way more efficient than cfl's? Where do you get them. Manufacturers are still making LED lights which are maybe 20-50% better because consumers will buy them. Cree can manufacture LEDs that are 4x better but consumers aren't demanding them.
These CFL lamps require a high frequency converter to start and operate the gas trapped inside the glass tube. They're normally NOT shielded in any way which sends out high frequency interfering signals due to the internal high operating voltage. The glass tube is not 100% seal proof, there is a certain leak rate which allows the gas and mercury to exit the tube over time and climb towards your home ceiling with the help of thermodynamics. Test smell one of your CFL bulbs: smells pretty bad!
Um try again..good educated guess. Incandescent lights work by the tungsten wire heating up in an inert atmosphere, when metal gets hot it releases light and heat. So if another base alloy or doped alloy was used more light could be emitted. Heat really isnt a concern although it is wasted energy.
TCP CFLs lasted a while. I actually rarely see TCP CFLs catch fire in the internet (especially the newer ones). The older ones were a fire hazard tho. Most of the ones that I see on fire are Feit, Greenlite, Or cheap Chinese brands.
@@julianurbaszewski4055 Update: TCP CFLs actually don’t last too long and can catch fire. Also one guy did call CFLs the Obama bulb. I’ve checked Facebook and some of the CFL fires were TCP brand.
A vast majority of consumables are made in China these days because their labor rates are cheapest and they have an inexhaustible labor force willing to work for about $5000 a year. Consumers always seem to consider price above all other criteria. Some comparable electronic components made in the EU or the US cost 3 to 5 times as much as the Chinese counterparts.
Very interested for this kind of industrial, if i want to build this kind of factories what about the price?could you advices? how can i get certification for the Lamp product?
At places where no A/C and no heater used (outdoor for example) the electricity saved is same as what’s shown on the package (in this example, it would be $50) At places where Heater are used most of the time, the electricity you saved is much less than $50 (you probably wouldn’t even save any at all) so it’s a bad idea to use CFL. And yes, I do have CFLs last more than 10,000 hours (I have some part of the business must be illuminated 24/7/365 and those bulbs last more than 1.5Year)
YAY! Let us promote our product as green and innovative, but let us outsource manufacturing to China; a heavily coal-based economy with slave-like factories.
You're so right about slave-like factories. Chinese factories give crap wages to its employees especially the labor work, but demand its employees to always work so hard and overtime without being paid extra and call it loyalty.
It is in a solid state which makes it much more difficult to harm anything as it can be picked up and disposed of, and it's 1.5mg. Someone that weighs 70kg (about 154 lbs) would need 20-60mg for it to be lethal, that is the absolute minimum...but it can be as high as 57mg or more/kg of body weight which is 4g. This would be lethal to small animals at most.
pcross84 It's actually not terrible unless it's been methylated. Granted, it's not GOOD for the environment, but there are many elements and compounds that are significantly more persistent and much more toxic.
I think the glass is just held while the screw rod is allowed to unscrew just like a screw (excuse the overuse of the word screw for nothing else came to my mind).
The mercury in a CFL is not all that harmful unless it mixes with water and becomes Methyl mercury. If CFL's are disposed of properly, the danger can be managed.
I hate to say this, for the ones that think all Phillips light bulbs are made in Europe are wrong! The incandescent plant lights are manufactured in China :(
I am confident that I have never had a CFL last for 10,000 hours! Additionally, what happens ten years from now when we have dumps full of these CFLs and their mercury?
But incandescent bulbs take more energy to use throughout the life of the bulb. Also, one CFL bulb lasts many times longer than an incandescent bulb, so it evens out.
True. I look forward to their future. But there's a ways to go yet before they're a practical consumer product, much less one accepted by the general public which is still fighting against CFLs because they look funny (I'm dead serious, that's a very common argument). Only recently have I seen any LED lights that can function as direct bulb replacements in stores and only a couple at that; everything else are low-output devices (like nightlights) or those bizarre lamps.
If you read the packaging, it says to wrap in tissue paper and dispose of in landfill bin. Ah greenie progress. Mercury ok in landfill, but heaven help us if we want to use incandescent which was recyclable with just glass and metal.
These lights are hard to get now because A more energy efficient and brighter lighting has arrived, the LED. Looks like LED is the way to go into the future, no mercury.

Yep.

All my light bulbs are still CFLs I don’t understand
