After a few months the bulbs start going off and then back on again by itself. Is this the bulb starting to fail? Replacing bulb seems to fix it.

Yes the bulb is wearing out if its going on and off best to replace it and do not touch the glass it burns so hot the oil from your finger will make a hot spot and short life for the bulb but do recommend lube on the brass part just a touch so next bulb change will not stick in the socket silicone works the best I think but very little so it will not run down onto the glass of the bulb also check the light sensor is not picking up light from another source

There are basically three components 1) bulb 2) light sensor 3) transformer/ballast. Take a look at the bulb to see if it has any darkness on the glass --- light sensors are somewhat inexpensive and try changing it. The last piece is the transformer/ballast --- normally if the bulb does not light that is a possibility.

I had the same problem. I replaced the bulb. It works for a while. Now it is going off and then back on again. I believe the ballast may be bad.

Most of the time it is the bulb.very rarely, but occasionaly it is the photo eye sensor.

quite often the bulb is the problem. having said that, i have had to replace the complete unit before because the transformer was going bad.

Sorry I can't help. I threw mine out after it failed to work in the lamp we bought it for. In fairness, I think the lamp was the problem, not the bulb.

I bought a bulb and it went out a short time after as well.but I replaced the whole TV instead of trying to fight the tv. I didn't try to warranty the bulb. Sorry this doesn't help

Mine did the same thing, after about 20-30 hours of use it stopped. The bulb will also occasionally flicker, though this didn't begin until it reached about 500 hours. For the money, I had no real complaints, but if you can afford it, I would go for the factory original...... most of these aftermarket bulbs do odd things, and rarely do they work perfectly out the box.

Sorry. I did not have that issue as everything worked fine. But you should be able to replace the bulb.

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

Have not had that problem. Ours installed like a champ and still work 2 years later. But we did go through several bulb returns (broken, cracked, damaged in shipping) before this.

I've noticed mine does not start up very well. Twist the bulb as if removing and then reinstall. It won't start immediately. Also, the indicator is not an LED like it looks, just a lens to the inside. Turn of the lights or shield ambient light, it might be on, you just can see it.

It is normal John, mine does the same thing without any adverse effects. Actually, I noticed that after an extended period, they shut off completely. Keep in mind, its not the bulbs, but most likely our trucks that cause it. It just isn't a strong enough current to be noticeable with the standard bulbs.

I'm sorry. I don't think I can be much help. I don't know what that bulb is. I ordered it because it looked like the one in my lamp. As it turned out, it was my lamp that was broken. The bulb in my new lamp got recently broken, and I put the one I ordered in. Therefore, I don't know how long it will last.

No. It's not the bulbs. It's the base. For some reason it shorts out. I've found it happens if you generate static shock while touching the lamp.my initial 2 went out with in weeks. (I bought 2) just had a replacement go out last week. So will be calling for a replacement again.

Hey there, ive purchased a cheap one and this one and I believe it may be another issue shortening the life of these bulbs... Maybe the fan ? Maybe excess dirt? Both of mine only lasted about 10 months (max) also.

If you have a meter that checks continuty you can check it with that.Be sure it is unplugged before you get into it but every time I have fixed one they all looked so bad but they couldn't last much longer,so I replaced them all.I have 3 heaters and I have had to replace them in 2 of them.I think this a weak point in them.I also had them replaced in the other one while it was under warranty.The bulbs are kinda expensive and I don't plan on buying anymore of these heaters unless they have a recall on them and give us some relieve.

I bought a box of 6 bulbs. One was not working from the very beginning. I installed two new bulbs and a starter, and it works now, but the noise is loud, and when I turn the switch on it gives a loud noise, which I didn't have before with old bulbs. My impression is that the quality of these bulbs is not good. Cheep price is not for free. I might be wrong. Good luck.

Make sure that the replacement bulb is a sony. The other ones start to go bad as soon as you put them in. You really can't tell if the bulb is any good because you are comparing it to the one that now defective. The sony I purchased is working fine better then any off brand I ever bought.

Sorry, I'm not sure. I do know that this type of bulb has a short life compared with regular bulbs. Generally they are not on for that long in any case.

I still use the same bulb and usually have no problem with them. Having one last for 3 months was unusual but that could happen, I was more disappointed about the second bulb not working at all. If you purchase them you should test both bulbs once received.
