Light-emitting diodes (LEDs) are great for solar projects because they will work with very low current (usually 20 mA or less).Tip:
The voltage of the solar panel you use should be equal or greater than the voltage required to run the LED.
So for example, you'll need at least a 1.5V solar panel to run a 1.5V LED - or, you could connect three 0.5V solar panels in series to get 1.5V.
We also carry mini incandescent bulbs
that operate at 1.5V but need more current (300-500 mA).
