Good luck, keep safe, and feel free to ask me if you have any problems.
By the way, Deal Extreme sells 100 watt and even 200 watt version of this LED emitter and driving circuit--that's more light than even I need but you might need more!
And don't forget: I made it at TechShop, and you can too. Go to www.techshop.ws to find one in your area.
