Solar lights: not as stupid as it sounds
Well these solar lights beat the snot out of the old solar walkway lights of yore. Using LED rather than incandescent means they’re about 10 times as efficient, meaning they’ll last all night with a reasonable output. The mini (pictured, and of course my favorite) will go 20 hours on full charge after 8 hours of sunlight. I do wish the company would give output in lumens, but they don’t. A word of warning: I’m fascinated with all things solar lately, so you’ll be seeing a lot of it. And power generation in general too.
