I don't think that's how it works. I think they are individual. I followed one of the reps on 420mag when they did this big light giveaway to the best growers on the site, so they could test out their lights and review them. Nothing but stellar reviews, and if anything went wrong, customer service assisted right away, but it was usually with stuff like shipping. No real problems with the product. After the reviews came in, damn near everyone on the site was buying TopLED. That's how I chose them. Crazy good product for a crazy low price. I was having a problem with one of my fans so I contacted Sara, the TopLED rep who did the light giveaway, and she sent me a new one no problem
