BACKGROUND
My family owns a cabin in the mountains that is 1 mile off-grid.
I am researching lighting solutions. We currently light the cabin with coleman propane lamps. Needless to say, these are high maintenance, only last a few hours, etc.
I read an article recently in Dwell magazine about an off grid house that used halogen lights on a wire track to provide power from a deep cycle battery. I'm trying to figure out if this is a possibility.
PROBLEM
I'm looking at sealed batteries right now due to ease of maintenance, specifically, Optima Blue Tops (deep cycle). Their specs are here.
I'm looking at a cable light system here where each light draws 20 watts.
I will not be using the transformer.
My question is, how do I calculate how long one battery will power one light, two lights, ten lights, etc?
Anybody offer any help? Thanks in advance!
