If your lamp and enclosure are UL rated then the on-die temperature is well within operating parameters for the 6000 hr+ lifespan. 6,000 hours? Where does that

If your lamp and enclosure are UL rated then the on-die temperature is well within operating parameters for the 6000 hr+ lifespan.
6,000 hours? Where does that come from?
The L-Prize bulb claims 30K hours; most of the LED lights I've seen for sale claim lifespans in the 25K to 50K hour range. Are you saying that 6K is all we can actually expect?
To actually get just 6K hours from a bulb that cost you US$30 or more (the L-Prize bulb is $70!) would be very disappointing.
- nickhalfasleep 13y agoSince the bulbs last so long, and it would be prohibitive to wait until a death rate of 50%, they use 6000 hours as the laboratory test time which has good correlation with information known so far from LED manufacturers. By that age they tend to be in a main sequence of life.
