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 ...

Four New Jersey cities have begun testing new street lamps powered by light-emitting diodes. The new LED lamps are expected to reduce energy consumption significantly, have a longer life expectancy ...

Heat, in particular, can cause these components to quickly break, so installing an LED bulb in a hot corner of your home or in a deep-set socket with poor ventilation can cause the lights to go out ...

The lighting industry has been buzzing with news of solid-state light source advancements for several years. As one light-emitting diode (LED) lighting fixture manufacturer puts it, flat printed ...

When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component to identifying the ...

Over on YouTube our hacker [VIP Love Secretary] shows us how to make a simple MOSFET tester. This is a really neat, useful, elegant, and simple hack, but the video is kind of terrible. We found ...

Needless to say, we’re fascinated by LEDs, laser diodes, and other blinkies. Although we can get just about any light emitting thing, the data sheets aren’t always accurate or available. For his ...

If you're operating your truck in Canada, know that the nation's National Safety Code 11B in fact "does put a percentage" on the number of diodes that can be out before an LED lamp is in violation.

Paul Crump, head of the High-Power Diode Laser Lab at the Ferdinand-Braun-Institut (FBH) in Berlin, will lead the newly ...
