China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

 Metal halide (MH) lamps are available in low, mid-range, and high wattages from 35 to 2000 watts (W). Mid-wattage MH lamps range from 175 to 400 W. All major lamp manufacturers offer MH lamps in this range, commonly in wattages of 175, 200, 225, 250, 300, 320, 350, 360, and 400.

MH lamps are a type of high-intensity discharge (HID) lamp that offers long lamp life, high efficacy, and good color rendering properties. In general, they are energy efficient and allow for good optical control. These qualities make them attractive for applications such as retail establishments, where both low operating cost and good light quality are important. Because of their long life, MH lamps are also appropriate for buildings with high ceilings and other facilities in which lighting is constantly in use for many hours at a time. They are popular choices for high-bay and low-bay industrial operations, warehouses, street lighting, and stadium and sports lighting. Like other gas-discharge lamps, all MH lamps require a ballast to operate. (See "Why do metal halide lamps require a ballast?")

MH lamps provide white light in a variety of correlated color temperatures (CCTs) ranging from 3200 to 5200 Kelvin, and are commonly available with a color rendering index (CRI) of 65 to 70, but can also have a CRI of 90 or above. They are superior in color characteristic to most high-pressure sodium (HPS) and mercury vapor (MV) lamps that have lower CRI values.

MH lamps compete with HPS lamps for outdoor applications such as streetlights, roadway lights, security lights, and pedestrian walkways. HPS lamps provide more photopic lumens per watt, but the whiter light of MH lamps provides better peripheral visibility at low illumination levels.

70,150,250,400,600,1000 Watt High Pressure Sodium ballast is U.L. Listed for safety and is manufactured by James Lighting, a leading manufacturer of horticultural lighting fixtures and bulbs.

The ballast is housed in a remote, core and coil ballasts enclosure and features an innovative "thermal chimney". The "thermal chimney" actually separates the box into two sections - one for the ballast and the other for the components - igniter and capacitor. The "thermal chimney" keeps the components cooler by not allowing heat from the ballast to reach them. It is a thermal protective barrier between the ballast and the components. The result is a cooler running unit with longer component and ballast lifespan. This ballast and housing are built to last. The innovative "thermal chimney" allows for effective cooling without the use of air vents and open ports inherent in other systems that allow for dirt, dust and water to contaminate the ballast system.
