Have you got a link to the Led modules that you're planning to run? I'd like read up on them a bit, and determine their lumen/$$$ ratio.
Actually no. The provider I am using is an LED wholesaler for outdoor, warehouse, and Stadium lighting. They don't list their prices on a website so I have contacted a rep directly. She provided me with the following chart and I hope to have the prices for each soon. They seem to be the best, compact, LED floods I can find.
