  • Still Quicker to flip a switch

  • Testing a light out in the daylight, fucking genius!!!

  • all that energy for a light????????

  • pfff

  • That looks like a fun little project.

    Would have been cooler if it had been made during night time though, so you could get an idea of how strong the light is.

  • I'm blind! Look at the display of candlepower! My eyyyyyyyyyyyyyyyyyyyyyes!

  • you can by one of those at costco in a three pack that is alot smaller

  • THAT IS SO STUPID.

  • Looks like I will have to use a cordless drill to wind it up

  • sounds like alot of winding. How about just using a lamp with and LED bulb plugged into the grid?
