Abstract
An enclosure for a light fixture and the method for making such an enclosure via the securement of a plastic or glass lens, wherein the light fixture has a window which does not have to be opened in normal use for replacement of bulb, but is normally accessible through a rear or side opening. The window opening is circumscribed with a front flange projecting radially outward. A double sided adhesive tape is affixed to the flange and is united with the lens. A metal cored trim covers and secures the flange and the unified tape-and-lens structure. This latter assembly may be further secured by crimping.
