Yeah, all the little "companies" use different catalog codes. That makes Cooper confusing IMO. They sould make Cooper lighting one comapnies and have catagories instead of having lumark, mcgraw-edison, streetworks, etc that all make the same lights with different names. EX, Streetworks calls the light we all know, the "OVX", but Lumark calls it the "RY". Sort of confusing if you ask me
There is the thing that says "DATE" but nothing next to it.
But there is a 4898 a bit above it.. Might it be the date?
