Energy controlled preheating
Depending on the available time for preheating, the ballasts should
give a preheating energy within the following limits:
E = Q + P x t

4.1.3 Lamp ignition
Ignition with preheating.
The following table includes values for the open-circuit voltages,
which an electronic ballast should generate for two different
ranges of ambient temperatures (indoors and outdoors).
Note: The open-circuit voltages are valid for:
- sinusoidal voltages (crest factor 1,4),frequency 20 - 26 kHz,
- applications with an earthed plate at a distance of 6 mm,
- properly preheated coils.
Ignition without preheating:cold ignition
The published lifetime of a lamp is based on a switching cycle of
165 minutes on and 15 minutes off with preheated coils,which is
considered as representative for general lighting applications.
However, the TL5 lamps can be ignited without preheating.This
will lead to more damage to the coil during the ignition phase.For
this reason,we do not recommend cold ignition with frequent
switching.However,cold ignition can be an option for not
frequently switched lamps,like lamps burning for at least 8 hours
per switch.More information on the dependency of lifetime on
preheating conditions and switching cycle can be found in the
separate brochure Life expectancy, lumen maintenance and service
life curves of Fluorescent lamps (TL and CFL-NI) 3222 635 18911.
