I'm finally starting to make the switch to HPS lights. My current setup has been 8 500w halos and a super noisy generator. Just recently purchased a new honda eu3000 that I will be using for the new setup. I'd like to run 8 150w from econolight. Now from what I've read on here its the 9x9's that have the caps already built in correct? Also how is everyone mounting them? Do they come with mounting brackets or do I have to make them?
