Step 1: Wiring

Picture of Wiring

The wiring is very simple. I have horrible soldering skills but i can wire this up in 20 minutes. Connect all the positive leads to one wire and all the negative leads to the other wire.
Run the Negative wire to the negative battery connector.
Run the positive wire to the toggle switch and run a wire from the toggle switch to the positive battery connector.

Enjoy the project and subscribe to my YouTube channel! Thanks!

Cool Lamp! Is there a formula for how many LED lights you can power from a 9v battery? Surprised it powered as many as you did. How long did the battery last?

So. update on run time. The battery lasted about 9 hours before it got too dim to use. I used the dead battery to make a 9v battery connector for easy battery replacement. So far I have built 2 more of these for friends using half the lights this one has and they are more than bright enough. Really handy lamp to have around and you can store extra batteries and a deck of cards inside it.

There probably is a formula but i just do trial and error. I have about 2 hours of run time on it so far. If i had to guess the 9v should last at least 6 hours.

The lights can be run on a 12v source. if you used a small SLA battery inside the jar and hooked up a charging jack on the lid you could make it run for days.
