I bought two bulbs less than year ago on Dec 28th and now one has already gone out. Are these defective bulbs? The original bulbs lasted four years

I don't know if this applies to your situation; but when my bulbs arrived I noticed that the boxes not been sealed, so perhaps they were touched by somebody along the packaging process. I made sure to clean them off with alcohol before the installation to remove any oil from fingers. So far, both bulbs (four months on one, five on the other) are still working fine. The HID bulbs are susceptible to localized hot spots (and premature failure) if the glass is touched during the installation.

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.

I occasionally get a bulb that is damaged or doesn't work. I test them on a lamp before use. One bulb I had to turn the switch twice.

So, mine has started doing the same thing. It has been months since I replaced mine and it is just now flickering. My guess is that the bulb is just cheaply made and not a true Factory bulb. For as cheap as the bulb was I wouldn't expect much over a year out of it but the flickering is pretty annoying. I don't know of a fix other than getting a new bulb.

I'm not sure about the warranty replacement bulb. Thankfully my bulb did not need to be replaced before one year it is still going strong. I would talk to the manufacturer if you have any concerns.

I've the cheaper bulbs on a different type lamp. All of the bulbs stop working after a few hours. The higher price bulbs I'm using in a verilux lamp which I have used for four to five hours for about 4 months and I'm still on the first bulb. If it was the lamp or not I can say because the verilux bulb would not go in the other lamp and the same is true of the cheaper bulb in the verilux lamp.

One bulb lasted 2 years and the other about 2.5. The OEM bulbs I have back in have lasted about 13 years and are still going. They are not nearly as bright.

my apologies but this item was purchased as a gift. Since bulbs are very inexpensive I would suggest going to a local hardware store or lighting supply and they should be able to help you find a replacement or provide you with the replacement number.

Mine have lasted over 2 years thus far, 24/7 usage and I have two units. I highly reCommend this, you aren't going to find a bulb that will last half as long, either way. It's a piece of mind.

Not sure what your problem is. We've had our lights for at least a year, and haven't replaced a bulb yet, although the batteries seem to be weakening so we'll probably have to replace them in a bit.

Sorry to hear of your connections. I don't have an automatic answer. I would chank the alignment of the holes and see if they match the alignment of the bulb prongs. If they don't match I'd say the replacements bulb is wrong.

Hi Dorothy, I gave the 2 bulbs to my sister. I will check with her to see if they are working. Ellen

I installed the bulb about 3 months ago in the hallway of my apartment building. I have subsequently moved so I'm not sure if it is still working. Sorry!

purchased 9 of these bulbs and one has quit already after less than 1000 hours. 4 1/2 months old. Likely will be a hassle finding where to replace it.

Those bulbs last at least a year or two. You should get in touch with Verilux. You may have a faulty bulb.
