White LED

Kerosine killer health benefits and requires only 0.5W per lamp for 5 candelas. Tukimara = "wicked lamp killer". Originally NiCd with independent tiny solar. Later recognized NiMH better. Also later recognized school based generation better than independent. But still carrying entire lamp to school.

Less than 0.5 W for 5 candelas. 3 x 1500mAh x 1.2V = 5.4 Wh (3.6 V). 45 yrs @ 6 hrs per day for WLED (3 Wh per day). 2-3 hours charge every 3 or 4 days should require 9-12 Wh? Consider OLPC 6.6V battery packs - 22 Wh Li FePO4? Weekly? Parallel strings of series WLEDs? But also need multiple lamps etc. So may want single cells.
