Yeah, I'd imagine a HPS NEMA would be a pretty big glarebomb. It's too bad they never made MH NEMAs, I know they made 70 and 100w PSMH yardlights but I haven't heard of a NEMA like that.
Yeah, I was hoping these were Mercury but no. Actually the flat waffle iron LEDs aren't that bad, light pollution here is mnimal thanks to them. Sitka, on the other hand, is horrible!
AEL did make MH NEMAs and Cooper still does, but I've never actually seen them used. GE never offered the 201SA NEMA in MH/PSMH though. All three companies offer PSMH bracket fixtures though.
