1000w lights are a fucking waste of money and I can tell you that catagorically. Well, if you have the luxury of having 4 or 5 of them in unison no their not. But if you have a situation where you can either use one or two 1000's or a combination of lesser wattage lights to make up the desired lumens. Always, always, always use more of the less intense lights. You will generate more light and illuminate a larger area.
