As reviewed in DIYODE magazine, September 2021.

This kit is much more versatile than the cheap regular LED testers available on ebay etc. Unlike the cheap testers, this kit not only tests two-pin LEDs at a range of currents, but also 3 and 4 pin LEDs such as bi-colour and tri-colour LEDs, like RGB LEDs.

Features

• Test 2-pin LEDs at a range of currents, from 1 to 40mA
• Test bi-colour and tri-colour (such as RGB) LEDs, both common anode and common cathode (selectable at the flick of a switch)
• Test superflux LEDs, including bi- and tri-colour types - test colours together or individually
• Momentary press-to-test button and continuous test switches
• Multiple slots at popular current levels for comparative testing
• Inbuilt LED voltmeter to show LED voltage (in dedicated section of tester)
• Voltmeter shows battery voltage with no LED inserted, for simple battery self-test (uses standard 9V battery)
• Open frame format, so USB rechargeable batteries can be used and charged inside the tester
• High grade ultraminiature DPDT paddle switches used for long lifespan and reliability
• Metal film resistors for reliability
• Resistor colour code chart on the back panel for easy reference
• Supplied with header pin style test probes for testing power LEDs
• Black finish high grade PCBs with white silk screen for legibility
