Crowd-Funded Project of the Week - Lumen Cache

This week's crown-funded project of the week is Lumen Cache: The New Approach to LED Lighting.  This Fundable.com project implements LED lighting on a 12 volt system - avoiding the excess heat and inefficient AC to DC conversion at each fixture.  A side benefit is the battery for energy storage and built in power failure lighting.  Here is the video:
