Am going to start building a headlight setup for use on the front of the 13' duck boat project and could use some input. Two options I'm thinking of are either a set of Hella or similar off-road lights which can be pretty straight forward but might tend to use a lot of electricity, or rigging something up with LED's. Would a few of these rigged together even approach the brightness I'm looking for? :http://www.oznium.com/high-intensity-led-spotlight I don't find any "lumen" rating on their site at all. The Hella or standard option would give me a choice of putting in some 110w bulbs, etc. Any thoughts?
