Do I just need a new light?
I just replaced the bulb in my old Amerlite this past Thursday. Mine had a 400 watt "globe" type flood lamp in it, looked like a big high-powered bulb that goes in a bathroom fixture. Of course, no local (what few we have) pool shop carried anything but the typical flood lamp looking bulb, and then only in 300-watt and 500-watt.
When I disassembled it, the gasket appeared to be in fairly good shape. Looks like the previous owner had gooped it up with something, maybe even plumber's putty. Whatever it was, it sealed fine and cleaned off the housing and face ring pretty easy.
From reading this forum, it was obvious that I needed to replace, not only the bulb, but the gasket also and set out to do that from the start. I bought a new bulb and gasket online.
Before I re-assembled everything I gave the gasket a good coating inside and out with silicone grease. I found it in the plumber's section at Lowes. It was quite greasy, but when finished, appeared to give a good seal. I toyed with using silicone sealant, but kept having nightmares about the next bulb change and trying to pry everything apart.

So far everything is working great! Light works fine and no leaks!!

One lesson learned: Shop around for the bulb! You can find it at non-pool places online for about $10 cheaper and more than make up for the difference in shipping charges by buying from 2 different online vendors!!
