Ok, so it seems like I'm always in the middle of fixing up a batch of old lights, but I finally got my hands on what I think is the last group for a while. It's a set of 12 65Q Fresnel's by Altman. These are what I believe to be 1st generation 65Q's, predecessor of the 65. They're brown/olive drab (but will be repainted because the paint is burned off the mid sections of the lights) and they have the metal handles. The situation is, there are 9 of these fixtures that need complete lamp base/reflector assembly replacements. These are the type with the smaller mirror dish in front of the reflective plate. They originally had bad sockets and the mirror dish had all but completely burned up. The other 3 have the same design reflectors/sockets but in good condition. Altman's new design only calls for a single spherical reflector. Buying the complete kit from Production Advantage (lamp socket,reflector assembly, and whip) would cost $50.00 each. Over the course of 9 instruments, that would still save me almost $400.00 as opposed to buying new. I'm debating on just doing the 9 that need it, or springing for all 12 as "preventive maintenance". Nine of them will be used exclusively as area downlights, and the other 3 would be used for whatever else, so that would mask any differences in light quality. Should I leave the 3 alone, or just make them all current? I have this preoccupation with making my instruments identical for easy servicing (I try not to mix things like old and new 360Q's for same-purpose lighting) and I would also think of it as stopping a potential problem before it starts. The upgrade would prolong these instruments for another 20+ years I'm guessing. Decisions, decisions. It would cost me an extra $150. and I would be pretty much guaranteed a like-new fixture after the fact, but the saying "if it ain't broke, don't fix it" keeps coming to mind. If you had the choice, what would you do?
