I use a large sears with a lead acic battery it holds a storage charge
and has a briht halogen bulb, its like a car bulb. But for long life and
use I think I would pick a flourescent with a lead acid battery. Many
white Leds have no more energy efficiency than incandesant, compared to
blue yellow or red LED, apx 19 Lpw-lumen per watt. Flourescent are rated
at 60-110 Lpw for T8. Many China nicads are junk. Good lights are
expensive. Mag lights are good flashlights, lifetime warranty.
