You can order them at Lights of America, I found them at a Farm and Home store..

My Ace Hardware has a few also, and they will order as many as you want, was 35.00. I hooked one up to the boat and used my cord and man I like the way it lights up, cann't wait to get it out on the water and see the differents.

Todd, what's the housing like? Plastic or metal?

I saw some at Farm and Fleet that were in a housing just like the halogen work lights. They were 45W I think and billed as same output as a 350W halogen. They were $40 though.
