Gotcha. Good deal.These lights are for a removable light rail i'm making for my second boat. Going with the LEDs will just make it easier to put the light rail on the boat and take it off. Wont have to worry about ballasts or running an additions generator. I do have a fan boat that i run HPS, and like them alot, but the boat is just too big to take out if only 2 people are on it.
