Hey Moms! Hey Dads!

Build a very cool solar jar light with your kids this summer! 

They'll have fun spending time with you and will learn about solar energy! 

Developed in collaboration with a science teacher from Pennsylvania, our build your own solar LED Jar light is a fun and creative way to teach and learn about solar electricity. Use your own mason jar or recycled jar and build a colorful LED light that automatically comes on at night and goes off at dawn. Choose from 5 different color LED's. I prefer to use a wide-mouth mason jar or anything that is wide enough for the battery pack. 

For optimum brightness the white jar light kit now comes with a 5V 80mA solar panel and 3-AAA battery pack. This kit is an additional $2.00 to cover costs for the additional battery, larger holder and larger solar panel.

 Comes with everything you need.

This kit requires soldering. Tools needed are soldering iron, solder & flux, hot glue gun, electric drill, wire cutters

Colored Jar light:

• 3V 70mA Poly-crystalline solar panel with wires (50 x 50mm)
• Dusk/dawn circuit board with wires and 2 x LED's
• 2 AAA NiMH rechargeable batteries
• 2 AAA Battery holder and wires (15 x 25 x 62mm)

White & Firefly Jar Light:

• 5V 80mA Poly-crystalline solar panel with wires (60 x 60mm)
• Dusk/dawn circuit board with wires and 2 x LED's
• 3 AAA NiMH rechargeable batteries
• 3 AAA Battery holder and wires (15 x 37 x 62mm)

A portion of the proceeds from the sales of this kit are being donated to help provide solar education to disadvantaged communities in Africa.

Also available: Our Pre-wired version of this kit for younger students.
