Thanks for the great info on LED lights! I was wanting to buy one, but the high cost was holding me back, plus the thought that much like all new technology when it's first released eventually gets "fine- tuned" .....think of hybrid cars and vcrs! By waiting a few years we'll be able to purchase a better product at a cheaper price.
