These light the canopy of a convenience store. They're 400w MV which seems to be too high wattage for the diffusers since all of them were either cracked or had a melted spot in the centre.
Wow 400W MV canopy lights? Normally I'd expect 175W MV lol. With new lamps this storefront must've been super bright! I love the glary hack-job retrofits on those troffers too.
The lamps looked way too big for BT/ED-28 so I think they're 400w. Yeah 175w MV is more than enough for this too imo, I'm not sure why people take the diffusers off when they retro from 4 lamp to 2 lamp. Makes the lights look odd and glary.
