Price: $9.50

This is the Constant Current LED Tester. It is comprised of a Constant Current Generator housed in a plastic box with spring terminals to fit the LED. After installing a 9v Battery, simply put the LED in and it will light up.

The spring terminals are colored RED and BLACK for easy identification of where to put the LED leads. The constant current is a fixed value and there are several sizes to chose from. The default value is 10mA which is a good starting point.

It requires a 9v Battery which is not included. The battery will last for months because there is no current draw unless an LED is installed.

This is NOT a kit, it is ready to work when you get it.

Get several different values so you can compare what your LED will look like operating under different currents. The current will remain steady regardless of the color of the LED.
