About the HMI 1200 W/S lamp

The MAC 2000 Performance comes with a double-ended
OSRAM HMI 1200 W/S discharge lamp installed. This
highly-efficient short-arc source provides an exceptionally stable
6000K color temperature, a color rendering index greater than 90,
and an average life of 750 hours.
The lamp is capable of hot restrike. This feature, however, is only
supported by the MAC 2000 Performance with electronic ballast.
The ends of the lamp have specially-developed keys, shown in
Figure 6, to ensure proper installation. Do not use HMI 1200 W/S
lamps with the non-keyed SFc 10-4 base.
Warning! Installing any other lamp may create a safety
hazard or damage the fixture!
The lamp has an average life of 750 hours. To reduce the risk of
explosion, replace the lamp before usage exceeds 125% of the
average life, i.e., before it exceeds 940 hours. To read lamp hours
from the control panel, please refer to "Readouts" on page 15.
For optimum performance, avoid turning off the lamp before it
has warmed up fully.

Lamp replacement

Important! Do not touch the quartz bulb with bare fingers.
Replacement lamps are available from your Martin dealer. Please
order Martin P/N 97010304.
The clear quartz bulb must be clean and free of any oils from
your fingers. Clean the lamp with an alcohol wipe and polish it
with a dry cloth, particularly if you accidentally touch the bulb.
To repl ace the lamp
1 Disconnect the fixture from power and allow it to cool. Lock
