If your concern is about the prices, you can find very reasonably priced lamps by Verilux on Amazon. Got mine for under $150, but there are ones even cheaper.

If you're simply trying to get an Open Source/DIY project together, power to you! An aside: I'm very grateful for my light box. I have S.A.D. as well as 2 anxiety disorders. Really helps me out and would recommend a box to anyone that is on the fence or unaware of their existence!
