On average 5000 hours but then again it all depends upon your viewing also.Bulbs are cheap at $100...well worth it !

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.

Amazon sells the replacement bulbs. The bulbs last quite a while. I keep my lamps on for up to 12 hours a day and haven't had to replace a bulb yet in the 6 months that I have been using them.

I've had a bulb last six months and I've had some last a few weeks. Most last at least a few months. They are great working bulbs and put off better heat then others, they are just hit and miss on how long they can last.

The info on the bulbs (6) I received with my growing system say "SunBlaster F54T5 54W HO 6400K". I found them and similar ones on the internet. I believe they are rated for 10000 hours. So far (after 2 months use) mine are working great!

Not sure the lumens. I did have two of these bulbs stop working after only a hundred or so hours. Not recommended.

To the best of my knowledge, there is not an hour rating. The original OEM bulb is supposed to last 3000-4000 hours as I recall. The first one that came with my projector lasted a little over 3000 hours and the OEM replacement only lasted around 1200 hours. I have this bulb now and the picture quality is just as good. It has about 500 hours on it so far. For the price, I'll be satisfied if I get over 1500 hours.

It depends in what do you gonna use them. In a hand lamp about 6 hours without turn it off. But they are the best. :)

Hello,The life expectancy is about one year based on your usage. We sell the replacement bulbs however you can get them online from other retailers as well. Thank you.

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.

I do not see the estimated life anywhere in the advertising, I have had this bulb last as long as 4 years at an average of 12 hours per day.

Hey Donald this is Mark, I have used these bulbs now for seven months with no burn outs. I think they are rated for 12v to 24v. They use about 3 watts. Good Luck Mark.

An LED will typically burn 50,000 hours or longer before beginning to lose brightness. They don't "burn out" like a traditional bulb.

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.

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

I use these bulbs in a candle warmer that I use probably 3-4 times a week for about 3-8 hours. The bulbs last about 4-8 weeks in my experience depending on frequency of use.
