2. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   HID lamps are used in high-performance bicycle headlamps, as well as flashlights and other portable lights, because they produce a great amount of light per unit of power. As the HID lights use less than half the power of an equivalent tungsten-halogen light, a significantly smaller and lighter-weight power supply can be used. HID lamps have ...

3. Metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Metal-halide_lamp

   It is a type of high-intensity discharge (HID) gas discharge lamp. [1] Developed in the 1960s, they are similar to mercury vapor lamps, [1] but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc ...

4. Ceramic metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

   Streetlamp with a ceramic metal halide bulb Ceramic metal halide bulb with G12 socket. A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI).

5. U-HID - Wikipedia

   en.wikipedia.org/wiki/U-HID

   Comparatively, the intensity of light from a U-HID lamp is at least three times stronger than a metal halide HID lamp in a color range of 4200K (cold light). U-HID is an abbreviation for a commercial USB circuit board meant to replace a USB keyboard on a PC. It is called a Universal Human Interface Device.

6. Hydrargyrum quartz iodide - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_quartz_iodide

   Like all HID lamps, HQI lamps operate under high pressure and temperature, and require special light fixtures for safe use. HQI lamps can produce different color temperatures when manufactured with different metal halides. They are relatively efficient light sources producing a high lumen per watt ratio (approximately 6x that of incandescent ...

9. Light-emitting diode therapy - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_therapy

   Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights. Following NASA's innovation in the 1990s with Light Emitting Diodes (LEDs) that emit a specific narrow light spectrum, LED Therapy (LEDT) showed significant potential. [ 1 ]
