Don't forget about EM/Exit lights

I looked in the archives and didn't find anything on this topic. For those of you who do commercial remodeling/cleanouts/dumpster diving, don't forget to look for emergency/exit lights with a battery backup. Most of these EM lights have a 6V lead/acid battery in them usually around 3-4 lbs each. They add up quickly.

They typically have a small transformer too.

I scrap a lot of exit lights. The newer ones have a small medium grade green board in them.

But the batteries in the newer ones are nicad. Bummer, still cant find a decent price for nicad.
