Im trying to find a retrofit kit for our exit signs here on campus. We used to use these universal 120/277v light panels that would just slip in and secure with double sided tape, but i cant seem to find them any more. Does any body have ideas???

There was a plethora of retro kits floating around, LED, CFL, rope LED, etc. I personally have not seen many lately.

A google search for CFL or LED retro's may be your best bet.
