HID lamps have also become common on many aircraft as replacements for traditional landing and taxi lights. [citation needed] HID lamps are also used in lamps for underwater diving. The higher efficacy of HID lamps compared to halogen units means longer burn times for a given battery size and light output.
for e.g. dash lights, gauge cluster backlights. Similar in size to W3W if with a T10 base. PC74 T1-3/4 (if removable) or fixed to holder [9] 1 14 V / 1.4W Used on circuit boards for e.g. dash lights, gauge cluster backlights.
Some bulbs have a phosphor coating on the inner side of the outer bulb to improve the spectrum and diffuse the light. In the mid-1980s a new type of metal-halide lamp was developed, which, instead of a quartz (fused silica) arc tube as used in mercury vapor lamps and previous metal-halide lamp designs, use a sintered alumina arc tube similar to ...
Because of the increased amounts of light available from HID lamps relative to halogen bulbs, HID headlamps producing a given beam pattern can be made smaller than halogen headlamps producing a comparable beam pattern. Alternatively, the larger size can be retained, in which case the HID headlamp can produce a more robust beam pattern.
Of all the sizes, 600W HID lights are the most electrically efficient as far as light produced, followed by 1000W. A 600W HPS produces 7% more light (watt-for-watt) than a 1000W HPS. [22] A 600W High Pressure Sodium bulb. An HPS bulb produces 60-140 lumens/watt, depending on the wattage of the bulb. [28]
High-intensity discharge, or HID lights, sometimes referred to as "xenon lights", are modified metal halide lights employing xenon fill gas. Traditional HID lights, such as those used for general lighting, have a long warm-up time. Headlights must provide light very shortly after they are turned on, and the xenon gas serves to reduce warm-up ...

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).
