We use Altman sockets in our Lekolites and I've never been told what the the metal ring, called a "Light Shield," actually does for the light. I attached a photo for reference. Any thoughts would be appreciated.

@Roddy Armory Theatre If it serves the same purpose as a similar punched metal plate normally supplied and employed with Altman's 360's and 360Q's, it minimizes leakage out the top of the chimney / rear of the reflector. If you think about a couple of pipes of 360's and / or 360Q's hung exposed to the patrons in the FOH of your typical small "Black Box" or church basement theatre, the spill shield minimizes the amount of light shining directly into the eyes of patrons and / or illuminating the ceiling of the theatre. To a small degree it effectively alters the precision of your "bench focus" in the sense if your cap is flawlessly aligned with the ring in place and then a careless person (I won't honor them by referring to them as a "technician") inadvertently drops the ring into the FOH seating and fails to invest the next 20 minutes locating and replacing it, your cap will sit a few thou' lower on the chimney and the lamp's LCL will be just that tiny 'smidge' (a precise technical term) below its optimal centering within the reflector. I trust this makes sense and, although I've never employed any Altman sockets on Century Lekolites, I strongly suspect your metal ring serves the same purpose.
Toodleoo!
