How many hours should I expect from this bulb? Update: I figured it out. 2000 hours.

I have had them in for months and it still is going strong. I seriously spent a fortune on the bulbs and all they did was burn out. I don't know but since I put the new one in they have been great!! Enjoy all the money you're going to save.

There is really no way to calculate the expected life. It depends on the type of fixture and, in the case of strings of bulbs as in landscape lighting, the distance from the transformer. Lamps closer to the transformer will not last as long as those further away due to higher voltage and the initial surge when they turn on.

It is my understanding that these bulbs are not replaceable. I would call Lithonia tech support and asked them. Also, take a picture and go back to who sold it to you and see if they can help. It is also my understanding that they are supposed to last for 30,000 hours which is about 8 years at 10 hours per day.

Hi, Donald. The bulb is bright and is very energy efficient, however the life is shorter than most standard candelabra based bulbs. It says the life is supposed to be 3000 hours . . . I have purchased three and of the three, two of them lasted less than 500 hours. Pretty pathetic for a bulb in this price range. The electricity saved does not balance the cost of the bulb. In my experience, the lamp is a poor choice.

Seems to be about 3-4 hrs. It depends on how bright you run the screen and what you are doing.

If these led bulbs are like other led bulbs they should last somewhere between 20,000 - 50,000 hours

The LED bulb in mine lasted about 4 hours. It just went dead; the switch is ok; tried new batteries, no use. Dorcy has no replacement parts for it.

Mine burnt out in a year after about 2000 hours of use. Couldnt see how to replace the bulb.

I don't recall after how long I had to change the bulb, but one, I do not keep it on all day at need. I have the lamp at my desk at work, so it is on for 8 1/2 hours a day, 5 days a week. The bulb lasts for quite some time, at least a year I believe before you have to change the bulb.

From what I have read the bulb life is 5,000 hours.The cost for new bulbs are about $200

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.

They say it's rated for 6000 hours. Can't confirm as I am no where near that amount of hours on new bulb. The housing is plastic.

According to UCI (I called them). It will shine/burn for 2 hours @150 Lumens, then it will start to dim and go into power saving mode.

I don't know. I hope 50,000 hours. I installed 15 of them 15 feet high in ceiling high hats. No problem, so far. Amazingly bright. Great color temperature for me.

I have not used it yet, but I remember the review I read mention 5000 hours for economy brightness and 2000 hours for high brightness

Its a L.E.D. Bulb rated for 50000 hours, if you use it 6 hours a day that 25 years of life. Most likely will out live us.ThanksBill

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.
