Why do these bulbs have such a reportedly short life-span? Is it because people touch the bulb thus creating hot-spots?

They only last about 3 months and I never touch the bulb. I use a glove when I put them in thinking the same thing.

I've been using flourescent bulbs in mine without any problem. Hope that helps!

Mine has lasted 2 years now. When you installed it you did not touch the lamp at all with your fingers and transfer anything to the lamp face? That maybe could create a hot spot and it burned out? Sometimes there is just a defect. When I first installed it I must have jarred the optical block so I had a rose tint across the top of the screen about 3 inches down. After a while you learn to ignore it, but I noticed recently that the line is gone. I moved the set a bit recently to get at a side connector and I am wondering whether that jarred something back in place. Now I won't move the set at all until the bulb dies again or something else goes south.

I don't have them in lamps that are very tight around the fan, but I have noticed an intermittent fan noise in one of the 150W bulbs I purchased that goes in a lamp that has a glass hemisphere that acts like a megaphone. I'm not sure if it's at a resonant frequency, or just a random issue in one of them. The base can get very warm (I just put my hand on one that's been going for an hour and a half overhead), but not too hot to touch. I'm not sure how hot is too hot, though PacLights may have more information.

Can't answer that....my bulbs failed in just a few weeks, but I just took the hit and bought some incandescent bulbs to replace them. They shouldn't sell such unreliable bulbs, for sure. Sorry.

Very strange. The same thing happened to me. You can get a replacement bulb pretty cheap at the big box stores. Was easy to replace. However be careful. When I first set it up, the bulbs got so hot that it burned a hole in the side of the box.

By the time they burn out (they are solid state - no delicate filament in a vacuum) the bulb, and you, will be ready to be thrown out!! You an always buy another one at that time if you still need it. If faulty, return for a refund.

They are H4 and do not harm the electrical parts of the car. People may say that they are more likely to burn out, but that is simply because they touch the glass part of the bulb with their bare hands which lets oil on your fingers to get onto the bulb, causing it to crack and dramatically shorten the life. So it is not the bulb that may appear defective, it is the carelessness and ignorance of people who do not read the instructions.

The packaging indicates you should not use these bulbs in a completely enclosed fixture. It doesn't say if there are safety concerns, or if the primary concern is decreased bulb life due to heat generation (which is minimal anyway).

The box says no, but I have several in a rather large enclosed outdoor fixture. Heat build up may ultimately shorten the lifespan of the bulb but they have been up and running for 4 - 5 hr per day for about 4 months without a problem. The fact it has been winter has probably helped things.

They claim there is a warranty but I have been trying to make contact for 6 weeks and can't get anybody to respond. I bought 4 of these bulbs on November 11, 2014 and so far I have had two of them quit working and a third only has maybe 1/2 of the LED's that will light up. I'm afraid that they are going to delay responding until after the 12 month warranty period is up and then tell me that they can't help me because the warranty has run out!

I've had very good luck with mine, and no issues. Be sure to use dielectric grease on the connections before installing the bulb. Its possible a lack of grease along with thr high wattage could be heating up the connection and shortening the bulb life. Use a plain paper towel when handling the bulb. Oil in even the cleanest skin can shorten bulb life.

I am no expert by any means but that's what my old one was doing before I installed the new one. They say not to touch the bulb. Did u try reinstalling it? Maybe u got a defective one, I don't know. Maybe blow some air in there to remove some dust? Again I'm not an expert, but for me no issues.

Good question, I don't know . But I thought the bulbs were supposed to last for a very long time.

Wondering if the installer touched the bulb with their bare hands and created hot spots thus burning it out prematurely.

I never had issues with the bulbs i always purchased from inovated and all of them are more than a year old, warranty i dont know but they are cheap so I just buy new ones.

Oh forgot, don't touch the bulb, with your fingers, use clean gloves or paper towels, that`s properly why your bulb went out to begin with. I have some there lasted for 8 - 9 years.
