Metal Halide Ballast for 320 Watt Metal Halide Lamps.

Electronic HID, like electronic fluorescent systems, significantly improves the performance of HID lighting. Electronic UltraMax® eHID ballasts use solid-state components to start and operate HID pulse start and ceramic metal halide lamps, allowing the following benefits when compared to alternative magnetic core and coil ballasts: • Improved efficiency vs. magnetic ballast • Maintain higher lumens • Enhanced color control • Operate more quietly • Variable dimming to 50% power reduction.

Core & Coil The typical electromagnetic ballast is the exposed core & coil ballast, which is commonly used as a component in HID luminaires. This type of ballast is called a core and coil because it consists of one or two copper coils on a ‘core’ of high-grade electrical steel laminations which are welded together. The ballast is then vacuum impregnated with a specialized varnish chosen for its electrical, thermal, and sound attenuating properties. All GE Core & Coil ballasts have a UL Class H thermal rating (180°C).

Probe Start Quartz Metal Halide lamps between the wattages of 175W and 1500W utilize an additional electrode, or probe, at one end of the arc tube to facilitate lamp ignition. Probe Start fixtures rely on the Open Circuit voltage to initiate the arc. 

Pulse Start Metal Halide lamps 150W and below utilize Pulse Start technology. Additionally, newer Ceramic Metal Halide Lamps require Pulse Start technology to ignite properly. Quartz Metal Halide Lamps 150W and less also require the use of an igniter to provide a high voltage initial ‘pulse’ to ignite the lamp. In QMH applications, once the initial arc is established the igniter stops pulsing and the lamps ‘warm’ up to full lumen output. Metal Halide lamps 150W and below utilize Pulse Start technology. 

Pulse Start High Pressure Sodium (HPS) lamps utilize Pulse Start technology. HPS lamps have no starting electrodes; rather, they utilize an igniter to induce a high voltage initial starting ‘pulse’ (3-5kV) across the main electrodes in the lamp. All HPS Lamps require pulse start ignition. In HPS applications, once the initial arc is established the igniter stops pulsing and the lamps ‘warm’ up to full lumen output.

F-Can Fluorescent Can or F-Can ballasts are traditional core and coil ballasts enclosed within a can typically utilized for magnetic fluorescent or electronic fluorescent ballasts. The reduced noise levels of F-Can ballasts make them perfect for commercial and institutional applications like; retail stores, grocery stores, offices, schools, and hospitals. Probe Start F-Cans for QMH house a traditional, probe start metal halide ballast in the convenient format of a fluorescent or F-Can. Providing superior thermal properties and sound attenuation, the enclosed and potted F-Can is ideal for interior environments requiring quiet operation. Pulse Start High Pressure Sodium F-Cans function the exact same way as a typical core & coil pulse start ballast. All of the necessary components of an HPS Pulse Start ballast like capacitors and ignitors are housed within the fluorescent can.
