Underwater boat spotlights

Got a little project in my head but need some help with the driver. I want to machine a solid brass housing to contain a single 50w led like this. Kinda like the typical pond light housing. http://www.dealextreme.com/p/prime-5...-22v-25v-42135. I will make 3 of them which will be submerged in water at all times. The water will take care of the cooling. I need a driver which can run all three simultaneously and need advice if this will work. http://cgi.ebay.com/24V-DC14-6A-350W...#ht_3391wt_957 . If it is compatible, do I need to make adjustments to not overpower them or make it work properly? All suggestions and comments greatly appreciated.



Better yet is finding a DC driver that could run all this from my batteries. No worry as I have an 400ah house bank, generator and a 50 amp charger. Similar lights are commercially available but pricing is over $1000 each. Figure I can do these for les than $100 each.
