Are these bulbs defective? Lots of people are complaining about the life of the bulbs.

The pair I got work fine light out put is fine the color is great pure white. The reviews aren't good I don't expect them to last a year but I like the color and the price.

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.

By the way, I had no problems with them. I acquired 4 of those lamps last year and they are still working just fine. I am not a professional photographer, but for the kind of application I do have for them it was a good deal, I mean, low cost and good quality. Probably you may find better ones for sure as always.

Mine has lasted six months so far. I really doubt that you can replace the bulbs, you would have to get the right leds and then you would have to solder them onto the board.

I've never had that problem. Buy quality bulbs from pet stores, not hardware stores. Also avoid bumping or shaking the fixture so you don't harm the bulbs.

Constant vibration over a period of time could cause them to fail as I've seen others do but they will still outlast any standard bulb. They will do fine with normal vehicle vibration and road bumps/holes.

No they are not this is one of the reasons that I am now upset they only lasted for about 2 or 3 months now they are flickering and I have several LEDs that went out. Another problem with the lights is that the housing fogs up it's like if they are not sealed the proper way

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 cannot tell you anything about replacement because I have installed eight of these same GU10 replacements and never received any bad bulbs. As for life span, I have not had any failures in 1 year of usage.

Hi Jane, This is a brand new machine and I hope I don't need to replace them for along time. They are flouresent so should last for years. Based on the last one my wife had the bulbs out lasted the sliding mechanism to adjust the lighting. She has owned several of these over theyears and never had to replace the bulbs.Hope that answers the concerns. Please give me a helpful vote if it did.

I've had mine since Feb/2014, not issues so far. Be sure to wear latex gloves when installing to avoid getting oils/dirt on the bulbs.I've mentioned in my review, they are a little brighter, but don't expect HID brightness.

mine lasted less than 7 months / 10,000 miles. I was really disappointed because I liked the bulbs when they worked. I contacted Philips customer service and they told me tough luck. I've vowed to never buy Philips again and to share my bad experience as often as possible.

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

Yes...I would echo what Rob said. I've been amazed at their longevity. I have them on a timer running about 5 hours EVERY night for the past two years. Only a few bulbs burned out...the other ones are losing their blue color finish due to exposure to sun/rain. Great bulbs.

Yes to both questions... Haven't even had to replace bulbs yet... Over one year... Use constantly..

We have had several of these bulbs last years. It really depends on how often they get turned off and on since that is the most wear on them. To give an example we have some of these that are hooked up to a motion sensor and some that are on all the time for security. The security ones have lasted up 3-4 years versus maybe 2 years with the motion sensor because of the frequent on and off. Hope this was somewhat helpful.

Sepehr--I thought you were asking if the company has replaced the bulbs. Hahaaaa! No, in the couple of months I have had the lights I have had four bulbs go out. At ten dollars a bulb from Lowe's.
