I had heard about Bio-Lite a few years back from their innovative wood burning camp stove.
I love the fact that this company is focused on renewable, eco-friendly system of outdoor gear. This light system is pretty neat too:
Bring indoor-inspired lighting to the outdoors with this rechargeable system of modular lighting & power. Anchored by 3 edge-lit lanterns providing bright, even light without any wasted space, the NanoGrid can light multiple spaces efficiently and easily with minimal setup. Included SiteLights provide overhead illumination, replacing harsh shadows with welcome ambient light. Designed to work together seamlessly, find the right light for any job with this kit.
You can find the individual lights here on Amazon. (the minis are only $15-$20!!!)
