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: bto 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 1050OC, 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 lose 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.
