6.3 Starters
In magnetic operation, OSRAM DULUX ® L (18W, 24W and 36W only) and OSRAM DULUX ® F lamps
require a starter for ignition. There is a choice of conventional glow starters or such that are known
as safety starters, e.g. the OSRAM DEOS
® starters. Conventional glow starters should be replaced
whenever lamps are replaced to ensure trouble-free ignition. This is not necessary with safety
starters since they last four times longer than conventional starters. In addition, safety starters
reliably shut down burnt-out or defective lamps in inductive or capacitive operation, which not only
saves the magnetic ballast but prevents annoying flicker from these lamps as they reach the end of
their life.
OSRAM DULUX ® S, D, T and CFL SQUARE (with two-pin bases) have a specially adapted glow
starter integrated in the base which ensures reliable ignition. Therefore they do not require external
starters. OSRAM DULUX
® S/E, D/E and T/E (with four-pin bases) are designed for ECG operation
and do therefore not have an integrated glow starter.
OSRAM DULUX ® S/E, D/E and T/E (13, 18 and 26 W only) can be operated under normal conditions
with magnetic control gear and an external starter. However, there are no special optimised starters
available on the market for this application. See also 3.2.3. In this mode, considerable limitations
can therefore be expected, such as greatly reduced lamp life with electrode blackening and longer
ignition times. For this reason, this mode of operation is not recommended or supported by
OSRAM.
For the operation of the OSRAM CFL SQUARE 4-pin with magnetic control gear and external starter
the OSRAM ST 111 Longlife starter is suitable. For starters from different manufacturers the
following parameters have to be respected.
In general an external starter has to be replaced together with a failed 4-pin lamp. Exceptions are all
DEOS starter types.
