Is there any information on how much weight the rim of a tank can handle? I'm thinking specifically in regards to clamp-on style lighting. I have had a pair of Kessil A160WEs with the arm mounts on a rimmed tank for years without issue, but I was thinking of adding some more light. Which got me thinking about just how much weight the tank could safely hold. Some of the larger fixtures have mounting arm options and that looks like that could a lot of weight being applied at a weird angle.
I've seen plenty of tanks run for years with clamp-on lights and I remember seeing one on here that had a couple of Kessils mounted to a T5 hybrid fixture using only the Kessil arms, which sounds like a lot of weight for the small mounting points so I'm curious just how safe something like that would be in the long run.
