I redid all my lights yesterday afternoon. Installed 5 27 watt leds. Hooked up in succession to a 12v marine battery. I wanted something I could take on and off being that I only have one hull for hunting/fishing/bowfishing so I mounted them to 1x6 board and use clamps to fasten to the bow. The whole light assembly can be installed or removed in about 30 seconds. Went out last night for a trial run and couldn't be happier with the results
