I have a big shop with 400 watt metal halide light fixtures. There are currently 4 of them but I need 8-10 total. Of course, the problem with that is I would be burning 3200+ watts. :duh2:
I've been looking into LED replacements, or converting some older fixtures to LED. All the conversions I can find claim a 100-120 watt LED with less than 12,000 lumens is a replacement for a 400 watt metal halide with 36,000 lumens.
Is that just because more of the light is lost in the reflector with the big MH bulb? Would they actually put the same amount of lumens on the floor? Here is an example:

I know they won't be cheap but if I could do the same with 120 watts as 400 watts I would save about $0.25 per hour in electricity!
