The Study Light

Our Work

A small, rechargeable solar light, built by student volunteers, so that a student without a wall outlet can study after dark.

Purpose Built

A solar panel charges a battery during the day. Two LEDs give reading light after sunset. The parts sit inside a case printed by student volunteers. By our estimate, a light is used about 6 hours a day. That figure is our own estimate, not a partner measurement.

What’s Inside?

Six parts, $5.17 in total. Volunteers print and assemble each light without pay, and the price counts parts only. Shipping is separate.

  • 3D-printed case, $1.10. Printed by student volunteers. Holds every part together.
  • 5V solar panel, $1.50. Charges the battery in daylight.
  • LiPo battery, $1.65. Stores the day’s charge for the night.
  • TP4056 charge board, $0.45. Charges the battery safely from the panel.
  • Two 5 mm LEDs, $0.12. Turn the stored charge into reading light.
  • Slide switch, $0.35. On after sunset, off by morning.
  • Total, $5.17. Parts only.
