im currently using a 400w MH conversion bulb on my setup. I just went to turn the light on and the light hasnt come on yet. The inside of the bulb has lit up but then goes back out. I switched the bulb to my HPS bulb and it came on fine. Does this mean my MH conversion bulb has blown? its brand new only been on for maybe 78 hours tops. feedback plz?
