High Intensity Discharge (HID) bulbs produce very bright light by creating an electric arc between tungsten electrodes housed inside a translucent or transparent arc tube. Common types include metal halide, high-pressure sodium, and mercury vapor lamps. HID bulbs are ideal for large-scale lighting in stadiums, warehouses, and street lighting due to their high lumen output and long lifespan.
Though less energy-efficient than LEDs, HID lamps are still widely used in applications that require intense, broad-area illumination. They are best suited for situations where light quality, brightness, and longevity outweigh the need for instant-on functionality or maximum efficiency.
