I just finished building my own lights. I got all the parts from rapidled.com. My total parts list came in just under $300, if I were to buy the same lights already built they would have been over $600. I just added these four Cree COBS to my blurple and I am getting great light. If you interested in a parts list, let me know, happy to send you what I put together. Here is the completed project. From my understanding these LED’s consume much less power.
