Photometric and electrical data
All lamp-specific electrical and photometric data is measured after 100 hours of operation under laboratory
conditions on reference equipment. For HCI
®
lamps the specified values relate to the horizontal burning
position for TS types and to the base-up burning position for other types, unless otherwise indicated. For
HQI
®
lamps the specified values apply to the horizontal burning position for -T and -TS types and for the
base-up burning position for -E and -TM types, unless otherwise indicated. NAV
®
lamps are all measured in
the horizontal burning position, and HQ and HW lamps in the base-up position. In other burning positions there
may be considerable differences in the measured values, particularly the luminous flux, color temperature and
life. With the exception of SOX, the luminous flux is virtually unaffected by the ambient temperature outside
the fixture. At low ambient temperatures down to around –50°C special igniters are needed.

Color shift
HCI
®
and HQI
®
lamps may show color shifts from lamp to lamp. These shifts may be due to external
influences such as the line voltage, control gear, burning position or fixture design.
End of life
High intensity discharge lamps (HCI
®
, HQI
®
, NAV
®
and HQL
®
) can be considered to have reached the end of
their life if:
• there is a marked change in their color or
• there is a significant loss of brightness or
• the lamp no longer ignites or
• the lamp periodically goes out and comes on again.
To protect the control gear and to avoid unnecessary radio interference, HCI
®
, HQI
®
, NAV
®
and HQL
®
lamps
must be replaced as soon as they reach the end of their life.
Guarantee
High intensity discharge lamps are only guaranteed if the prescribed operating conditions are observed; in
other words, in particular if the maximum permissible lamp temperatures are not exceeded and the lamps
are operated only on appropriate control gear. In addition, the lifetimes specified by OSRAM apply only to
operation in fixtures that do not reflect radiation onto the lamp (see Fixture design, page 6.50).
POWERTRONIC
®
control gear from OSRAM enables high intensity discharge lamps to be operated with
perfect results and a high degree of intelligence.
For system operation you get an extended guarantee on the POWERTRONIC
®
ECG and on the relevant
HCI

®
lamp.
