Some lux V lights claim an LED lifespan of 1000 hours. Do you think in the case of the U2 lifepan of the LED is increased if used more at lower power levels? While I don't expect to ever need 40+ days of max brightness, will reading at minimum level take the same toll? Common sense says no, but maybe someone can confirm.

yes, under powering an LED will increase it's life span. I don't think you have to worry about the led degrading much in normal use. Even on high. By the time it's enough to worry about, many many many years of use would have passed...

I'm not worrying. Even if the Lux went belly up (which I'm sure it won't anytime soon), SF would make it right.mbirds said:

The LuxV in the U2 would probably have almost unlimited lifespan on the 3 or 4 lower levels.
I would also bet that on level 5, one step below maximum, the LuxV lifetime would be comparable to a LuxIII driven at 750 mA, or 10,000-20,000 hours.

I think U2 use LuxeonV portable.
So accroding the datesheet from luxeon.com. after 500hrs the LED will decrease to 70%-90% output depend on your output level.
