BY THE WAY ... Its always interesting to see that people look at LED Technology for 240V and 110V Mains only... hmmmmmm

Think of your house as a car, with many rooms, where each room has 1 x 12V light.
Each 12W Light is supplied with 12Volts from 1 x 12V Battery.
Youtube it / Google it / Study it / build it .. The implications are that your initial investment, will save you much money over possibly 20 years +

Look at Off grid Cabins etc where they double up on Batteries to create 24V and 48V systems. (The only reason for this is to deliver a Specified Load over a specified distance) - Simple OHMS Law - secret to understanding that is learn Basic Electronics Theory - and play around with the 3 things that mean something - Volts / Amps / Resistance (The Resistance is the Cable Length and diameter)
Watts is the Power so 10W divided by 12Volts is ?Amps ... get it
Only worry about 12V / 24V / 48V - Only Design for 10W & 15W LED Lights - There are Maximum cable Length Charts on the Net free - example .. a 15W Light on a 12V System must not be connected by a Cable that is Longer than 6 meters @ .75mm Diameter - Why - plug the numbers into an OHMS Law equation to see why .. FUN !!
