I am new to this forum so first thank you in advance for taking my question. I recently removed some high bay light fixture from a warehouse I was working in and they were 400 watt MH highbays running at 277 volts. But here is the weird thing they were lamped with 1000 watt MH lamps, and the were working and seemed to be brighter than the 400 watt lamp that was supposed to be in the fixture. My question is WHY was this working, how efficiant was this set-up and what would be the wattage consumption of this fixture.
