LED tester
Posted by richg1998 on Tuesday, December 21, 2010 10:16 PM

Some here have asked about testing LED's. I have been watching a discussion in a SoundTraxx forum about this type of tester. Some have been buying them in the USA and other countries.

I test my own with a small 12 volt gel cell rechargeable battery, 1k resistor and multimeter.

Do a ebay search for

Handily LED Bulb Test Box Tester

If you do not like ebay, Do a Google search for

Handily LED Bulb Test Box Tester

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.

Heck, I just put a resistor on one leg of the LED and touch both legs to the terminal of a 9 volt battery.  The LED either works or it doesn't.  That's my tester.

There are many who cannot do this that is why I posted the info. Some need to keep it simple for whatever reason.

The ones from ebay are buy it now for about $5.00, free shipping and they come from China.

Some in the SoundTraxx Group have bought them from and the delivery was good.

Ranters will no doubt disagree.

Below is a DIY tester for those who like to make up their own testers.

It is not hard to test LED's, but the CES tester sold by All Electronics for abt $9 saves me time, and it can test bulbs from very low to high currents.  Since it can test typical LED's in parallel, I can compare brightness and color.
