Yield Lab 1000w HPS Cool Hood Reflector Digital Grow Light Kit is the best. I had a problem with the ballast that kept blowing the fuses in my home and finely poppedthe fuse in the ballast. ( By the way there is a backup fuse next to the fuse being used..) but customer support was supper fast with a replacement, saving my project. They also, included a new HPS bulb.Great Job AceGrow, This is the way to run a Great USA Company.Thanks,Ronco Man !!!!
