Nice little tester

For LED tester

Mine had some dry joints for the battery holder and it had popped off during transport. But a bit of solder fixed that and it works well especially for all the tiny surface mount LED's I wanted to experiment with.

Hi Eric,
I so sorry to hear that. This never happened with any of the testers I sold. Happy to know that you fixed it. Let me know if you need any part.
Regards

Excellent led tester!

For LED tester

Does its job. Shipped quickly. Well made. Conveniently sized. Now I'm adding sentences to get over 100 characters. Thank you.

Very simple device, but perfect for my requirement

For LED tester

I just needed something resilient to test a large selection of LEDs and I could not be bothered to make something myself. This product helped me to sort through the plethora of devices I needed to assess, which was very helpful.

If the creator is thinking of any upgrades, I would suggest a switchable constant current source and a larger battery voltage to test LEDs with larger forward voltages, but that shouldn't detract against this product.

Hi Carl,
I'm glad you found it useful. Next version will for sure have a constant current source and a variable voltage because a lot of customers asked for the possibility to test high power LEDs. Also going to add the possibility to test serial LEDs like Neopixel and ws2812b like LEDs (I enumerated 5 variants right now).
Thanks for your support.
