We just sent a small number of the El Capitan light to RMSK for sale. These are HA and Brass, SS to follow later this week. The specs are any AA battery chemistry, 1 to 8 power level and medium optic. The LED is the Cree XP-G R4 2S.
#4 output: AA Alkaline 450 fc.......Lithium-Ion 680 fc
#6 output: AA Alkaline 570 fc.......Lithium-Ion 1350 fc
#8 output: AA Alkaline 650 fc.......Lithium-Ion 1850 fc
The size is identical to the original 5 LED Kiliminjaro that we made five years ago. I do not have time for run time testing as I now have 6 more lights under development that I am working on. And a surprise or two coming.
