TaoTronics 27W waterproof 12v to 30v outdoor LED floodlight from Amazon
http://astore.amazon.com/diaxaris-20 The daylight review of this very heavy duty waterproof LED floodlight. This is set up to run on a pretty broad range of DC power, from 10V to 30V, and can be readily adapted to custom applications that are powered by any common 12-24v power tool battery or vehicle battery system. I will be using these in several off grid lighting projects. Cost of these runs from just over $20 each to around $50 depending on when and where you buy them.
