For ‘TL’5 HO 80W:

Regarding the figures and the preceding tables the following
remarks should be made:
1) The actual data given in this Product Information brochure is

also the subject of discussion in a working group of ELMAPS
(European Lamp Manufacturers Association for the Preparing of
Standards).This will result in due time in new data in the rele-
vant IEC standards.Therefore the data given here should be
considered as preliminary.

2) If the lamp current (I

D

) is varied between the limits given at

normal operation, additional heating is optional, but not strictly
required.

3) In addition to the relation between the lamp current and the

Lead-High current, the Lead-Low current (I

LL

) may have any

value < I

LL

max.The maximum allowed values for the Lead-Low

current are given in the tables. Lead-Low currents > I

LL

max.

will cause accelerated end-blackening.

4) It will be clear that practical lamp - ballast combinations will

have settings deviating from the ideal “target setting” curve.
The grey area in the graph indicates the “acceptable” range of
deviation. It is difficult to indicate quantitatively the effects on
lamp life for settings deviating from the “target setting”.
It is generally observed that higher values of the Lead High 
current (I

LH

) lead to strong end-blackening. If the Lead-High 

current is below the “target setting” the electrode becomes too
cold and sputtering of the emitter may occur. If the Lead High
current is reduced below the grey area, a short life of the lamp
will occur.
