Here's a pair of Sylvania/Powerlite B2255s from the same Parking Lot the B2213s were in, oddly this is the only pole with B2255s. Maybe these are replacement lumes?
I think they might be, they're the same brightness as the B2213s. Well, unless they retrofitted everything to 400w MH. I still think the ballasts are quite old though since they're super loud when on.
