Emergency exit lights never really got much attention until the whole wasted energy topic got out. And now it looks like even the simple escape lights are getting their share of attention, minimal but still energy-wasting sources that could be improved.

This is something that business or even movie houses may want to consider, particularly the ones who are operating for most parts of the day including the dark.
