1000 watt metal halide ballast kit, Operating conditions, such as lamp burning position and normal variations in supply voltage or ballast characteristics, can affect lamp color and light output of MH lamps. Normally, at its end-of-life, an MH lamp won’t start because the mix of materials in the arc tube changes. Therefore, the ballast can no longer sustain an arc.
1000 watt metal halide ballast kit. An HID ballast typically steps up the incoming line voltage to a higher voltage to start the lamp. Thus, a common problem with a multiple-tap ballast can be an incorrect tap connection for the line voltage available. A defective core and coil ballast will usually show signs of its condition, such as darkening of the case or cracked or crumbling insulation, which definitely indicates excessive current flow or excessive heat buildup.
Because of 1000 watt metal halide ballast kit construction, an F-can or encapsulated ballast does not allow you to see the winding. However, these two types often give off a strong odor if they have burned or melted ballast windings. You can make voltage measurements on an HID ballast, similar to a fluorescent ballast, using a multimeter. When you replace a defective ballast, also consider replacing the capacitor, ignitor (if used), and lamp.
Pulse start metal halide is a new technology. The bulbs are brighter, last longer and have better maintenance of lumens, can be run 24/7 without having to shut down. It is hard to find ready made ballasts for pulse start, but the kit form is very cheap, and is available in huge numbers of different wattages. The 400w metal halide horizontal lamp from JAMES puts out 40,000 lumens initially, lasts 20,000+ hours
1000 watt metal halide ballast kit Capacitor. Generally, a capacitor fails by either shorting or opening. When a capacitor shorts, it can damage the ballast, lamp, and/or cause excessive current flow, which may cause a breaker to trip. This type of failure is more typical in the older oil-filled (metal oval can) capacitor type than with the dry metalized film (round plastic can) type or the non-PCB oil-filled capacitors, which typically have an integral interrupter. A metal can type capacitor may bulge when it fails, particularly if it doesn’t have an integral interrupter.
