Next thread down (
LED not that efficient.) has had 40 replies in 2 weeks. Have you looked at it?
"...8 element Mpow light..." doesn't tell much. Pix or Specs?
What I use is
iZoom night light. 200 lumens, shaped like a light plate wall switch with a magnet base. Pull it off what it's stuck to and it makes for a[n awkward] flashlight. They use 4 AA batteries so with a solar charger it qualifies, maybe on the low end.
I was expecting the thread to be about
q=light%20tube%20skylight like Velux or Solatube.
Apparently, bulbs burn out and LEDs dim with age. There's a lot more in that thread — color temps & etc.
