Mercury Vapor 400W Mog
ED37 CO
Product family description
Mercury Vapor lamps feature low initial cost, but have
higher operating costs than HPS or Metal Halide due to its
lower efficiency. The clear mercury bulb has a bluish green
appearance and the Deluxe White has a higher color
rendering. Mercury lamps get dimmer over time and rarely
burn out, so it is wise to replace them and restore light
level.

Rated average life is the life obtained, on the average,
from large representative groups of lamps in laboratory
tests under controlled conditions at 10 or more
operating hours per start. It is based on survival of at
least 50% of the lamps and allows for individual lamps
or groups of lamps to vary considerably from the
average. For lamps with a rated average life of 24,000
hours, life is based on survival of 67% of the lamps. (351)
