Sorry, came across this new "4w" LED light from BLT. Claims a 20hr run time from 4 Alkaline AA's. Doesn't seem right to me if it was running at 4w. I would say 2hrs would be more realistic. Anyone? They got some sort of Canadian black magic juju battery thing happening here or what?
This is "old" led... If you almost DD Luxeon III from 4AA (using small resistor) at the beginning you can rate it 4W. Then when the voltage is dropping, the power drain and the light output are dropping to... It will probably reach claimed 20 hours :nana:
