150 watt metal-halide bulb in fixture, about halfway through warmup ... Electronic ballast for 35 W metal halide light bulbs. The electric arc in metal-halide lamps, ...
To power an HMI bulb, special ballasts act as an ignitor to start the arc, and then regulate it by acting as a choke. Two types of ballasts exist: magnetic and electronic (square-wave or flicker-free). Magnetic ballasts are generally much heavier and bulkier than electronic ballasts, as they consist primarily of a network of large inductors ...
Most newer generation electronic ballasts can operate both high pressure sodium (HPS) lamps as well as metal-halide lamps. The ballast initially works as a starter for the arc by its internal ignitor, supplying a high-voltage impulse and, later, it works as a limiter/regulator of the electric flow inside the circuit.
Example of a round 150 W magnetic induction fluorescent lamp. In 1967 and 1968, John Anderson [4] of General Electric [5] [6] applied for patents for electrodeless lamps. In 1971, Fusion UV Systems installed a 300-watt electrodeless microwave plasma UV lamp on a Coors can production line.
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 ...
Metal halide lamps produce almost white light, and attain 100 lumen per watt light output. Applications include indoor lighting of high buildings, parking lots, shops, sport terrains. High pressure sodium lamps, producing up to 150 lumens per watt
