Well, the NEMA tag is different, but that's 'cause you changed the ballasts. I want the L-150 too. these were pretty common here, but with light upgrades from PC to relay on the intersates, these are fading out. Some of these are common in Southeastern Mass. If i come across any, i'll get as many as i can for people here. All of these that I know of are HPS.
Well look at the refractor closely...
