/diy/ - Do It Yourself

Not quite electronics nor workbench, but I installed some new lights in the basement today, running on 100 % off-grid solar power.

Which means that I probably have the biggest battery powered lamp on 4chan, since they'll produce 3000 lumens, 24/7, for 25 days on battery power only.

You'll have to do the calculations. I would bet that you'd be better off with some ultra low quiescent current draw linear regulator than a 7805 in any configuration. Pulsing large amounts of current through a linear reg is not usually a recipe for efficiency.
