This is my first experience with a UV. My 12x, 36w came from a pet store in Alaska that was closing. The owner was selling all his left over merchandise on eBay. So, I got a new $200 UV very cheap as well. After it blew two ballasts and two bulbs, it wasn't cheap anymore. But, the WorkHorse 3 ballast fixed it right up.
I hope that you have a good experience with your new, UV.
