Could you please tell me what the life rating of these leds is in hours? Thanks!

i've seen specs with at least 30000 hours. I'm sure this can vary higher as Bryan mentioned.

One of these batteries: http://www.amazon.com/gp/product/B004AT21R2/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 will power and array of 8 of those LEDS for over 30 hours.

Anywhere from 6-12 months of normal use. I believe they are rated for ~200 hours. These aren't "long life" bulbs. They're on the opposite end of the scale, "high performance".

Theoretically, leds should last for years regardless of operation hours. If they fail from defect, it is usually right away. That said, voltage spike or damp will shorten average lifespan.

theses led last very very long.i have some that are 4 or 5 years old..i do have them on timers but they are on 12 hr a day and as i said some of them are at last 4 years old..

They are a sealed unit. you cannot replace a bulb they have 104 leds and are a half inch thick. Somewhere I read they are supposed to last 30,000 hours. May be able to get more info from led wholesalers.

I don't think so...they are LED's and therefore not consumer replaceable...However, LED's usually last ...nearly forever!

It's hard to predict the future, of course, but LEDs are expected to outlast incandescents and fluorescents, so they should last many years, even at 12 hrs per day. Certainly long enough that the technology and prices may be significantly different by then.

The lights are LED so they do not need replacing. LED's have 100,000 hours rating, so @ 4 hrs per day, that would be 68 years to replace. I think there will be better lights by then.

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

The LED lights cannot be replaced, and should never need to be replaced. LEDs have a life over 30,000 hours, which means they will never need to be replaced, even after 10 years of usage. They are solid state technology that will not lose brightness over time. Additionally, 25% of the LEDs are actually Infrared (IR) so they will appear "off" to the human eye, when in fact they are working.

I use them in a 3 lamp light stand to illuminate my computer, they work great. But in a dark garage, maybe you will need 3 to 4 units to make it light. As for burning out, led's have a long life like about 25,000 hours and I expect mine to have mine for a long time. They have a great white light and really shine great. Try one or two to see if they would work OK. I tried Compact fluorescent lights in my garage but they didn't work too well. During cold weather they would not come on so I went back to regular bulbs. But I would like an LED light for the garage. Hope this helps Paul

All LED flash lights have a hours or minutes rating on them. Depending on how many lumens it has will determine how long the batteries will last. The light I have only lasts 120 minutes before they fade or burn out.

I haven't tested it (Thankfully) but I think I read in the packaging that it would last up to 48 hours. They are really fine LED lights so I could imagine it would last several hours for sure.

They are LEDs so you shouldn't have a problem. I didn't notice them getting all that hot. Granted, I haven't left them on for hours at a time and then tested.

Does not appear to be replaceable very easily. But this shouldn't be a problem because when I look at other LED lamp descriptions on the Net, the ones that give a lifetime spec generally say they're rated for 20,000-50,000 hours of usage.

On average, LED bulbs last 50,000 hrs which translates to a little less than 6 years of continuous use. Odds are, you're not going to use the light 24/7 so it'll last considerably longer than that. I've been told 25 years, but time will tell. They're very bright. Bought a dimmer switch compatible with LEDs and that solved that.
