Metal Halide Ballast Information

 

Metal halide lamps, a member of the high-intensity discharge (HID) family of lamps, produce high light output for their size, making them a compact, powerful, and efficient light source. These lamps require electrical ballasts to regulate the arc current flow and deliver the proper voltage to the arc. The ballasts are available as CONVENTIONAL magnetic or ELECTRONIC.
Electronic Ballasts are more expensive than conventional ballasts but have the following significant advantages

Lamp color & lumen output regulation
Metal halide electronic ballast has less than ± 0.5% change in output power with a ±10% variation in input line voltage, and less than ± 2.0% change in output power over the full range of accepted ansi lamp voltages. the result is excellent color stability. A typical "magnetic-lag" ballast has more than ±15% variation in output power with a ±10% variation in input line voltage, and an additional ±20% change in
output power over the full range of accepted ANSI lamp voltages; resulting in very poor fixture to fixture color stability and consistency.

Energy savings
Metal halide electronic ballast uses approximately 10% to 17% less energy than a " magnetic" ballast.

Improved lumen maintenance
Typically, a Metal halide electronic ballast extends lamp lumen maintenance from 5% to 15% versus a "magnetically" ballasted lamp.

Small size & light weight
Metal halide electronic ballast is compact with extremely small and lightweight designs compared to large, heavy magnetic ballasts.

Heat losses
Metal halide electronic ballast has a higher efficiency and therefore much lower heat losses than magnetic ballasts.

One piece assembly
Metal halide electronic ballast replaces the ballast, capacitor, and the ignitor of the "magnetic" ballast systems in one integrated unit.

High power factor
Metal halide electronic ballast has a power factor greater than 0.95, much higher than that of a "magnetic" ballast.

Quiet operation
Metal halide electronic ballasts are sound rated "A" for quiet operation in interior commercial applications.

To summerise the advantages of Electronic vs Convention Gear
Compact and Lightweight / Fast Start / Same Ballast for Metal Halide and SON / Remote Operation to 25m / Safety features for all Lamp Faults
Heat Noise and Flicker Free / Energy Saving of up to 22% / Enhanced Lamp Life / Constant Colour and Power / Excellent Colour Rendering

Metal Halide Lamp Information

 

Whether choosing a fitting that requires the G12 or G8.5 capsule lamp, or the Rx7s double ended lamp, there is still another choice to be made: to buy a lamp with a quartz burner or a ceramic burner.

The principle benefits of ceramic metal halide are 3 fold, by using ceramic instead of quartz to contain the arc it allows the lamp engineer major opportunities to improve the performance of these lamp types.
1. The ceramic can run at a much higher temperature, usually about 1050°C, this higher temperature, gives a couple of benefits.
• The higher the temperature the higher the CRI (colour rendering index), so this drives some of the improvement and gives us CRI of between 80 & 95 dependent upon the colour temperature ie the ceramic gives excellent colour rendering.
• This ability to run at higher temperatures also makes the system much more efficient, the 15% improvement we see versus quartz made products is based on the ability of the ceramic to withstand this.
2. The additional benefit is the ceramic’s resistance to sodium loss through life, as mentioned earlier the quartz allows chemicals to disperse through the walls, ceramic being a more dense material is much more resistive to this and hence gives us excellent colour control through life.
3. Reproducibility is key to consistent product performance, this is another area that works well with ceramic products, the ceramic can be manufactured and assembled to very tight tolerances unlike the quartz equivalents which by the nature of their processing can have quite wide variation

To summerise Ceramic Metal Halide gives a higher efficiency, a quality white light with excellent colour reproduction, and exceedingly good reproducibility allowing very consistent colour, not just lamp to lamp but throughout the lifespan of each lamp.
The lamps also enjoy a much longer lamp life than those with a quartz burner lasting at least twice as long.
