Would it be a good idea to replace the kryption bulbs in the emergency lights [usually built into the exit sign] with cluster LEDs? and add a switch to conserve battery power if needed be?
Based on my observations with the frequent hurricane evacuations last year, the office inland [moms] we decide to ride out the storm...
the bulbs puts out little light and will last about 2 hour 30 minutes or so before it

dies....
I figured with cluster LEDs it would be better and not to mention last longer than 2.5 hours on a 12v 7ah battery
