The explosion-protected pendant light fittings
of the EV series are for universal use
and offer, due to the different sizes and
usage of nearly all lamp types, solutions for
a wide variety of applications.
The following illuminant types can be used:
• Incandescent lamps with a rating of
150 W to 500 W
• Mixed light lamps with a rating of
160 W to 250 W
• Sodium, Mercury and Halogen metal vapour
lamps with a ration of
70 W to 250 W
• Induction lamps with a rating of
55 W to 165 W

Especially the new QL induction lamps
when used in the EVQ light fitting types offers
a remarkable advantage against normal
lamps when life span and their abitlity to
cope with the different environmental temperatures
(see the illustration below) are
taken into consideration.
