Is this a special project to be built?
Check out Candle Power Forums, these people are passion and build their own lantern:

Or just buy a Fenix TK40 output (13 - 600 + lumens) CREE MC-Quad and the transmitter, the last 150 hours in 1 hour NiMH batteries 8xAA run.
In the context of 277 lumens high just under 4.5hrs modified his demands. 630 lumens in turbo-creation of at least one hour duration, and only 8 AA batteries, albeit small.
Without batteries, the device weighs 284grams and the regulated output voltage remains constant until the cells are dehydrated.
Depending on how you need a bright light is a small 2xAA Fenix LD20 is running 71hrs / 9 Lumens, 5 ha / 94 lumens and 2 hours / 180 lumens. Only 56grams without batteries.
With a package of 20 pounds of the battery of these fires can be run continuously for months, the issuer has an estimated life of 50,000 hours.
Get the low discharge NiMH cells such ass Sanyo eneloop. Some NiMH Standars in a week sitting in his flashlight.
Visit your local store, lithium batteries for military aircraft models sold. You need some special circuits for LED lamps to power. These circuits are becoming more common as we move into more general use LEDs. The problem is that LED devices are currently operating, in contrast to incandescent lamps that are operated in tension.
The miners, hunters, emergency responders are already on these systems, some of which are multiple arrays of 3-watt LED, which are so brilliant, they really dangerous.
