wouldn't mind being able to build small solar powered lamps, costs 1 component n some steel.
It's a pain having to run cable from 'one side of the map to the other' so i can light up some 'jungle'
..Contains it's own small battery that stores during the day, turns on/drains with certain darkness.
Id rather just have a solar switch, with an inverter toggle.
That way you could make one indoors too, and control if it is a daytime or nighttime lamp.
Both a nice idea: self sustaining lamps, with solar panel and Batterie and smart lights which only turn on when light level is below 50%
