Instructions For Use Protective-tube lights
ENG
Fundamentals
Waldmann protective-tube lights
are available with and without
ballast unit.
Lights without built-in ballast
unit must be operated with a
separate ballast unit.
There is a difference between
conventional and electronic bal-
last units.
The ballast unit installed must cor-
respond to the lamp.
A selection of suitable ballast
units are found in the Appendix on
page 19.
Lights with built-in ballast unit
can usually be operated directly
from a power source.
Conventional or electronic ballast
units are built in, depending on the
type of light.
Lights without ballast unit
When using conventional bal-
last units, a starter is required
additionally. It can be built into the
light itself or possibly be mounted
externally.
In some lamps, the starter is incor-
porated inside the lamp.
When using electronic ballast
units, no starter is required.
Lights with ballast unit
Lights with a built-in conventional
ballast unit usually have likewise
a built in starter.
When using electronic ballast
units, no starter is required.
