When I used to grow with metal halide lights, ( back in the 80's), those bulbs had lost some brightness after the first grow, and were surprisingly dimmer after 2 grows, so much so that I only did 1 or 2 grows per bulb, having looked at lumen drop of graphs of HPS and HID charts, using one of those bulbs for years is robbing yourself of yield potential, I could not imagine using a bulb for 17 years,
its also fun to see people who I know use bulbs "like" the pro bulb responses, and the people I know who love and use LED like the pro led responses, its always enjoyable to watch the replies play out!!!!
