High Pressure Sodium Bulb Illumination Vs. Quartz
Both high-pressure sodium and quartz halogen light bulbs offer increased life over standard incandescent light bulbs. Both produce a white light and operate at high temperatures. Does this Spark an idea?

Illumination
-
To produce light, a high-pressure sodium light bulb uses an electric arc that produces an extremely high temperature controlled by an electric ballast. Quartz halogen bulbs operate by heating a filament contained within a quartz-coated capsule containing bromine.
Brightness
-
High-pressure sodium bulbs emit a brighter light than standard incandescent bulbs, the brightness of the bulbs means they are often used for commercial lighting, including stadiums and arenas. Quartz halogen lighting is brighter than standard tungsten filament lighting and is used in indoor and outdoor residential lighting systems.

Lighting
-
The brightness of a type of lighting is measured in lumens per watt, with high-pressure sodium bulbs offering 50 to 140 lumens/watt compared to quartz halogen's 12 to 22 lumens/watt. In lifetime hours, a high-pressure sodium bulb lasts an average of between 16,000 and 24,000 hours, compared to a quartz halogen bulb's 2,000 to 3,000 hours.
