Hve not used it at all. Theresolution is crappy at any setting in the program you are using or no matter bow far or close u r to the screen. Its not a projetor, its a toy that does not function

Not long. Seems like mine was dead after 4-5 hours of use over several months. Never replaced the battery so I've been stuck with a white, plastic bulb for years now. Wouldn't purchase again.

I would say the battery life depends on the display settings. With full illumination, I think it's about 6 hours.

I can't say how long the LEDs would last if burned constantly. Mine is turned on for about fifteen hours a day and it is still working fine after several months.

that's a good question - I don't know the answer but Contour says the life of the bulb is around 20 years but even then it has a lifetime warranty - I think the bulb will out last me :o} - I see LED light bulbs rated at 10,000 to 100,000 hours -- I really like mine and seems very well engineered

The Cree LED has a usual lifetime of many thousands of hours of continuous use. The casing or circuitry is more likely to fail first.

A few hours. I have yet to read of anyone who has gotten more light. It works long on first use only, then very short battery life.

I've had mine running 8-9 hours a day for the last two weeks, plus lots of time since my review. No brightness issues that I've noticed. The cause of the diminished brightness in LED products, especially cheap ones, is that the designers intentionally over drive the LEDs to increase the brightness. This also shortens the life of the LED.

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.

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

Not that I can see, but who cares. LED Bulb should last ten thousand hours plus, And for the twelve dollars I bought it for, I think it's a bargain!

Never done a rundown test but I have used it for over an hour without it dying. They have extended batteries as well. Remember, the LED does not come with a battery and it uses Sony batteries. Using the regular battery should get you 1-2 hours and the extended should double that. I rarely use it at full power as well.

It depends on what you're using it in . Some flashlights will use them up in 20 minutes others will last for 10 hours or more

I have never tried it, but I can tell you it lasts a LOOONG time!! Its the handiest light I ever bought!! From using it ,I estimate about 3-5 hrs continuous.

I have no idea!..i do know that its on 2100 hrs and still as bright as ever and has performed flawlessly..so I will get another one for sure.at the price I paid I wont mind if it only last 2000 hrs but im sure it will last at least 3000

More than 2 hours actually. I left mine unplugged running at max brightness overnight to see how long the battery will last. I was up for more than 5 hours before falling asleep and it was still running. Light at max wasn't as bright compared to when it was plugged in though. There's most likely a circuit preventing the battery from over discharging as it turns on then off for some time still before I plugged it back in.

I don't know as I only use it for 1.5 hours at a time and I never really checked but I am sure you could get 4 hours or so all I can say is that this light is super bright and I sell led lighting for a living.Solid in the hand and overall impressed with the quality...
