LED Tester (#11627)
Price: $9.99
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.
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.
