I want to spread the word about Big Clive’s DIY LED product pages. He not only has tons of projects listed for you to make and create, but he also sells printed boards and other materials to get you started. This particular project involved retrofitting a 500W halogen floodlight enclosure with 180 LEDs (RGB) to make a monster bright LED floodlight. You have to check out Big Clive’s website!
The “Things to Make and Do” section is where all of the DIY projects are listed.
