so I work at sportmart, and i noticed that the lighting is a combination of what looks like several 1000w Mh lamps and several flourecent lights. Anyways, is this right, do department stores use Mh lights for lighting or do the bulbs im seeing in my store just resemble Mh lights. Well i noticed that one of the Mh lights in a string of like 8 lights over one aisle just went out. And has continued to not light for a couple days. So is that basically what happends when your bulb burns out, it just doesn't ignight anymore??
