temperatures exceed the ignition temperature of the
hazardous atmospheres.
• Do not operate in ambient temperatures above those
indicated on the luminaire nameplate.
• Install with lamp base up within 25 degrees of
vertical position.
• Use only the lamp type and wattage as specified on
the luminaire nameplate.
