I was using a Eye Hortilux 600w HPS in a Sun Tube (a reflector that encloses the light in glass so you can use a fat to blow air through the tube, allowing you to position the light closer to the plants) for flowering. For the past week, it would flicker once every 15-20 minutes. This morning the light never even turned on (its on a timer set to come on at 6am) until I manually turned it off/on a couple times, waiting 5 minutes for the lamp to warm up in between tries. When the light finally came on, it seemed to be more of a blue spectrum, and it was fairly dim. The light is about a week under 2 months old. Did I just get a bad light? Do HPS lights need to be changed that quickly?
