Saw this thing, on teh webz... I thought : 4 LEDs can't do much, however.
Position it as high as you can.
At current Belgian rates, one bulb uses about €15 a year, burning 4 hours a day...
So if this lasts then it's a win.
Solar powered, with a magnet to attach to any surface metal. Portable.
And it looks good too 🤔😁
Don't know the shiney time and life xpc but if so then a few more gets the night for free....
