Are this LED bulbs rated for continuous use? Can they be illuminated for several hours without overheating?

I am using them as back up lights. There are 5 1.5w plasma LEDs there is an heat sink on the case. They should be fine in continuous use. I have seen them in H3 fog-light form. I would get two sets if you need a pair. Sometimes one of the elements will flicker. I would get 4 keep the best 2 and return the second set. They are all made in china and the quality is inconsistent. This gives off the best 360 light and runs cooler than all the others I have tried.....DO-NOT use the 5w cree's in continuous operation.

As Del answered I've not used them on a regular basis, but I have had the bulbs for 4 years and use them around the holidays. They seem to last for quite a while.

I don't really know, as we have yet to,have one burn out. I think LED's last much longer than reg bulbs, so it should be a long time before they would burn out. So far, we are very happy with this fixture. Very bright & lights up a broad area thanks to the swivel of the lamp arms.

Not that I can see, but who cares. LED Bulb should last ten thousand hours plus, And for the twelve dollars I bought it for, I think it's a bargain!

Yes they can, BUT, mine lasted about 3 months and then died. I replaced them with 40w (watt) equivalent LED bulbs which use 7.5 watts to produce the same amount of lumens (light) as a 40w incandescent bulb. LED bulbs should last around 20 years or 100,000 hours or more. Fluorescent lights are on their way out. The other thing about LED bulbs is that they are smaller and less bulky than CFL bulbs and they don't change color with age.LED bulbs also contain no mercury and require no special disposal.

I don't know for sure but I don't think so. These bulbs don't have a real long life span. I have them in small pot lights as outdoor lighting, so they are on for about 7 hours a day 7 days a week. They last about 15 to 20 days.

I leave the LED's on all night and there is no heat from the bulbs. They are supposed to last 22 years at 4 hours a day

The LED bulb is claimed to have 20,000 hours life span. I have used for two years and it still works fine. There is bulb sold on Ebay and 12 are sold, so I guess some one did need to replace them.

That is the great thing about LED bulbs, they us much less electricity and do not generate any heat! The answer is yes you can.

probably not.. depends upon the design of the bulb and the fixture they are being used in. I am using them in the bathroom in an overhead fixture, where they are seldom on for more than 30 &gt; 60 minutes, and would not know how warm they get as they are out of my normal reach. However, the heat sink on most LED bulbs I have dealt with does become quite warm (to the point where you can not unscrew them without a glove or something) after being on for a while. So, i would say any "120 vac house lighting" bulb would not be cold after 2 hrs, as they are pushing a lot of power thru the LED's (to get the maximum brightness) and need to dump the excess heat into the heat sink (which is why they have the big heat sinks and say do not use them in totally enclosed fixtures where the heat can't get out).

G7 gives a 5 year warranty on the lamp but I found no rating for the average hours. Led's work on a different principle than incandescent lamp. They use a light emitting diode which lasts a very long time under normal use. I am not sure how then convert the 115V down to a usable power for the leds, which use roughly .7V each but that might be the deciding factor on longevity. I have had these installed for several months of continuous usage and they are still going strong.

theses led last very very long.i have some that are 4 or 5 years old..i do have them on timers but they are on 12 hr a day and as i said some of them are at last 4 years old..

Yes. The original bulbs lasted a month.I replaced all of them with the Brightech LEDs over 6 months ago. They are still working.

I can't say how long the LEDs would last if burned constantly. Mine is turned on for about fifteen hours a day and it is still working fine after several months.

They are a sealed unit. you cannot replace a bulb they have 104 leds and are a half inch thick. Somewhere I read they are supposed to last 30,000 hours. May be able to get more info from led wholesalers.

An LED will typically burn 50,000 hours or longer before beginning to lose brightness. They don't "burn out" like a traditional bulb.

No doubt, in the product description there should be a coma between the "50000 Hrs Lifespan" and Guaranteed. I don't know any manufacture that guarantees their lamps for the duration of their rated life and would not expect that to be the case with these LED's Lamps. That, of course is only my opinion - for what it is worth!!!
