Yeah, I’m all over LED’s for all lighting. Heck, those solar powered yard lights stay on all night in our yard, even during the winter. I was really surprised.
Those yard lights are so efficient because they are self contained. Short runs from charger to battery to light. You start pushing amps through wires and efficiency drops. Ohms are your enemy.
It’s a light... it’s a battery charger... it’s a WEAPON! (spike that goes in the ground - get aluminum)
The ultimate “prep” - solar powered yard lights...
