Many years ago, like 1993-1994 a couple friends of mine worked at an electrical supply store. The inventory was totally screwed up and needless to say, we got many lights out of that place for free. I at one time had 4 400watt 3 600watt and two of those little 150's all HPS. Like a dumbass I sold all but one of the 150's. The 150 is just basically a parking lot light. Man I wish I still had those lights.
That light has been around a long time and get this. I just changed the bulb in it for the first time since i got it yesterday. I can't believe it has lasted all these years(still works). Its been used, stored, left in sheds, not turned on for a year or two at a time, moved many, many times.
