One of the first projects that most people do on an Arduino is to light up or flash an LED. It seems ultra-simple because it ...

There are extremely high powered LEDs out there, and most of the ‘creative’ uses of these are extremely high-powered flashlights, complete with heatsinks, forced air cooling, and beefy power supplies.

A few years ago, the highest power LEDs you could buy capped out around three watts. Now, LED manufacturers are taking things to ridiculous power ratings with 30, 40, and even 90 watt LEDs. Getting ...

This article describes a rainbow flashlight I designed for a personal project. The intended application compels a multimode, multicolor, compact flashlight/tent light to be driven by a small built-in ...

Fig 1. Single 1-W LEDs can serve as high-power, high-brightness devices. Fig 2. Certain LED applications fall into a gray area where low-power and high-power components both can fit the bill. However, ...

Loosely defined as LEDs with at least a 1-W capacity, high-power LEDs are a hot technology. Before you can apply them effectively, it helps to refresh your knowledge about these versatile lighting ...

In high-power lighting, needs are emerging for LED luminaires rated to 100, 200 or even 600 watts (over 60,000 lumens), to cover wide areas. The higher-power heat sinks increase in size and weight ...
