The project pertains to a standalone LED test tool that can be used to avoid the hassle of complicated LED testing using LED’s datasheet, multimeter, or power supply. There are several factors ...

The BTS256-LED Tester measures luminous flux, illuminance, color quantities and spectra of individual LEDs and traditional light sources. Larger size light sources can be measured by attaching the ...

This circuit can be used to test up to three LEDs at once, connected in series. You can easily increase that number by using a higher supply voltage. If you do so, you should allow 2.7 V for each ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...

Loosely defined as LEDs with at least a 1-W capacity, high-power LEDs are a hot technology that’s very much in the market spotlight. Since their emergence, they have found themselves in a diverse ...
