CAT# LT-100
$8.95 each
Pocket-size led tester. Makes it easy to check functionality, color, brightness and uniformity. Plug any leaded LED into one of 12 positions on the socket strip to test at current ratings from 2-50ma. The seven middle positions on the strip are set at 10 mA allowing comparison of LEDs in those spaces. Requires 9 v battery (not included).

Good deal for the price
This is a inexpensive knock off of the LUMEX LED Tester Box at 1/4 the cost. It does however use a cheaper header than the screw machined header on the LUMEX tester so the insertion
life will be less. If you need to test hundreds of LEDs you would need a ZIF socket which even the LUMEX tester does not have. The new LUMEX tester now tests 3 terminal devices for the same price but the price is still closer to 40$ than 10$. Good addition to the tool box.

LED Tester
I love the LED tester. It is useful for testing LEDs of any color and makes determining polarity easier.

handy LED tester
I paid $16 for one of these at a local electronics store for work, and it has been extremely useful for identifying LEDs from the scrap bin. It simply uses a 9 volt battery and resistors (and a push-button switch) to limit the current through LEDs - no fancy current regulation, so the 2-50mA current ratings are a rough indication and not accurate depending on the voltage drop of the LED under test. Accuracy aside this is a great price for a tester that quickly allows you to determine the polarity, color and relative brightness of any LED. Highly recommended!

A bit defective
There was a defect in mine. The current-limiting resistor for the 30mA branch is 3300 Ohms (the same as the 2mA branch). Other than that, it works fine. I figure it should be around a 230 Ohm resistor instead. It seems like this is an isolated problem, since it works for others.

Great little tester
Got this with my last order of LEDs and was thrilled to be able to instanly light my new acquisitions.Great device for a great price.
