Incandescent bulbs typically last between 1, - 3, hours and are fully dimmable to help you increase their average life span. With a variety of unique CFL and LED bulbs to choose from, you don't have to compromise on style when making an environmentally sound choice for your pendant light.
There are several benefits to using CFL and LED bulbs: not only do they require less energy to run, they are economical. LED bulbs last 25, hours or about 3 years.

LEDs are known for being long-lasting light sources. Producers claim some light bulbs can last 25 years or more. But how long do LEDs really last? LEDs often have a lifespan of 5, 10, 17 or even 20 years printed on their packaging. While these numbers look attractive to customers, they can be misleading too.
This is why we recommend our customers make or ask us to make a customised calculation. The expected lifespan of a light source depends on how it will be used daily. Calculating the lifespan in years is easy. If we suppose that an LED light is on for an average of 7 hours a day for days, this will add up to hours a year. If the LED light has an expected lifespan of 25, operating hours, it will last 9. One thing to keep in mind when buying a lightbulb is the luminous decay.
This is sometimes mentioned in articles, but not often. Also, in settings like bathrooms, when the light is on for a shorter time, the warmup time of some CFLs is also sometimes annoying. Does anyone have a link to a website that reviews bulbs for quick warmup and their performance with a lot of on-off cycles? This would be valuable, especially if it included full-spectrum in addition to ordinary CFL bulbs.
A CFL that is globe shaped and works well in bathrooms would be a valuable thing — my bathroom and all in my neighborhood have 2 bathrooms with 8 bulbs in a line above a long mirror, if regular bulbs are used this is Watts — and a lot of waste heat to be counteracted during cooling season.
They claim 25 years. A couple died completely after a few years. They flickered first probably due to cheap capacitors and then went totally dead. The others after a few years were so dim to be unusable. The 25 years bit is total BS.
I had an amber colored incandescent lightbulb that lasted for about 25 years. I forget the wattage, probably or I went back to visit this apartment in Manhattan in the mid-nineties and was astounded when my friend who I gave the apt. My 5 year curly bulb lasted about 5 months.
Of course, I left it on constantly in my pantry because I hated going into a dark room, pulling a cord, and having to stand there waiting for the bulb to come on and warm up so I could see… I really want to see immediately when I pull the cord.
If not, I have to take a flashlight to see what I am doing. I live in a really old antique house, and there is always the possibility of sharing space in the dark with a mouse. I am really hoping they improve the quality of the curly bulbs, make them normal looking so my lamp shades fit on them, and improve the color so I can tell what color things are. I pulled something out of the washer one day that looked brown, and I thought I had somehow ruined the garment, but when it got to real light is was red, as always.
I hate to think what my skin must look like in that light! As has Larry, I have had three or four CFLs, with a seven year lifespan marked on the package , fail in less than a year. One died in a manner that tripped a circuit breaker, and it was the only thing on that circuit at the time. My laptop failed two weeks after the three-year warranty expired. Someone should do a serious investigation of the claimed life of CFLs. In my informal study involving maybe 20 bulbs so far 2 were essentially DOA lasted less than a month 10 have burned out in about the same time frame as incandescents sharing a lighting circuit months and the rest are still going, including a couple that are years old.
How does the energy consumption change if the real world lifespan of these much more complex and toxic lamps is not much more than an incandescent? Why are the manufacturers and CFL proponents allowed to claim such inflated lifespans?
Another issue not evaluated is that, in many cases, there is a non-zero probability at all times that a bulb will break accidentally e. Simple probability theory or statistical simulations will reveal that the observed ratio of the lifespans of CFL or LED to incandescent bulbs may be half or less than the advertised ratio of their lifespans.
I did a simple simulation in a spreadsheet using a macro. Result: The ratio to simulated observed lifespan for the LED compared to the incandescent was about
