High Intensity Discharge
Ballast Data – Mercury Vapor
Mercury vapor lamps from 175 watts through
1000 watts will operate satisfactorily on equivalent-wattage
probe start metal halide ballasts.
For electrical characteristics of these wattages,
see metal halide ballast information.

HAZARD WARNING – USE OF MERCURY VAPOR LAMPS
These lamps can cause serious skin burns and eye inflammation
from ultraviolet radiation if the outer envelope
of the lamp is broken or punctured and the arc-tube
continues to operate. Do not use where people will
remain for more than a few minutes unless adequate
shielding or other safety precautions are used. Certain
types of lamps that will automatically extinguish when
the outer envelope is broken are commercially available.
