ENERGY EFFICIENT LIGHTING:
The selection of the light source should be based upon its efficiency,
maintenance, and cost of the desired appearance of the environment.
Incandescent Lamps: Low efficiency, short life lamps that
produce a warm white color which is excellent for people and fair for landscapes.
Mercury Vapor Lamps: High efficiency, long life lamps that produce
a blue-white color which is good for people and landscapes.
Metal Halide Lamps: Very high efficiency, medium life lamps
that are good for people and
landscapes.
High Pressure Sodium Lamps: Very high efficiency, long life
lamps that produce a yellow white color which is poor for people and landscapes,
but good for security and safety lighting applications.
