However, mercury-vapor lamps are falling out of favor and being replaced by sodium-vapor and metal-halide lamps. Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive ...
Cycling: LEDs are ideal for uses subject to frequent on-off cycling, unlike incandescent and fluorescent lamps that fail faster when cycled often, or high-intensity discharge lamps (HID lamps) that require a long time to warm up to full output and to cool down before they can be lighted again if they are being restarted.
Metal-halide lamps, which produce light by an arc between two electrodes in an atmosphere of argon, mercury and other metals, and iodine or bromine. These were among the most efficient white electric lights before LEDs, having a luminous efficacy of 75–100 lm/W and a relatively long bulb lifetime of 6,000–15,000 hours; because they require ...
A front view of a Stagebar LED striplight. LED stage lighting is a stage lighting technology that uses light-emitting diodes (LEDs) as a light source. LED instruments are an alternative to traditional stage lights which use halogen lamp or high-intensity discharge lamps. Like other LED instruments, they have high light output with lower power ...
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 ...
Automotive HID lamps emit considerable near-UV light, despite the shield. 2014 Toyota Corolla The low beam features LED lighting, halogen high beams, and LED daytime running lights that also illuminate at a lower intensity to provide the front position light function
