High intensity discharge lamps contain compact arc tubes that enclose various gases and metal salts. They operate at relatively high pressures and temperatures. High intensity discharge (HID) is a ...

The tech behind the 2-year project, which includes lights installed on nearly a dozen buildings, all coordinated through a single controller.

The six-volt sealed beam produced a soft yellowish light, barely as much as a standard 25-watt lightbulb. Throughout my 50-year auto service career, I've seen headlights evolve from sealed beams to ...

Step 4: Remove the bulb. Most of today's halogen high-intensity-discharge (HID) or light-emitting-diode (LED) bulbs are held in place by thin wire clips or rotating bayonet-style retainers. Don't go ...

It is no mystery that light is essential to human life. Since the discovery of fire, humans have developed various artificial ...

Our last HID (high-intensity discharge) test was in 2018, when we assessed D1S lamps. Environmental concerns over the mercury they contained have seen the focus switch to D3S since then ...

The 2014 Lexus ES 350 gains LED fog lamps along with its high-intensity discharge headlamps. Along with other models in the 2014 Lexus lineup, the 2014 ES 350 integrates Siri Eyes Free Mode ...

Metal Halide Lamps A metal halide lamp is a high-intensity discharge light source in which light is produced by radiation from mercury and from halides of metals such as sodium, scandium, indium, and ...

In conventional light diffusers, optical characteristics such as diffusion angle and direction can only be tailored during ...
