A 750w mercury lamp does not exist, do you mean a 400w, 700w, or 1000w MV?

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).


LED brainwash? No, people uses them cuz they work well for them.

If this 750 is on the breaker, it can be the wattage of all the system (lamp+ballast). If so a 700W seems the right wattage.

thats what it is a 700 watt MH high bay light (Or possibly 1000 watt). it looked like MV because the older bulbs are coated and more dim.

Are you saying they are as LOT brighter and BIGGER than the lights you see in the highbays in Best Buy, Home Depot, Lowes, and most stores with high bays?
