Replacing the lamp
Important! Do not touch the quartz bulb with bare fingers.
Replacement lamps are available from your Martin dealer.
Please order:
• OSRAM HMI 1200 W/S
• Philips MSI 1200
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 replace the lamp:
1 Disconnect the fixture from power and allow it to cool. Lock
the head horizontally with the top up.
2 See Figure 8. Release the 4 quarter-turn fasteners marked
with arrows on the rear plate. Pull the lamp assembly
straight back as far as it goes and let it rest on its retaining
pins.
3 See Figure 9. Pull the retention spring on the left end up
and then swing the end of the lamp out. Pull the other end out of the socket.
4 See Figure 10. With the nipple on the bulb facing the back,
insert the right end of the new lamp in the socket. Pull up
on the left spring and snap the other end into place.
5 Lift the lamp assembly so that the lamp is level with the
center of the reflector. Push the assembly straight in until it
seats, making sure the lamp passes through the reflector
opening. Lock the 4 quarter-turn fasteners.
6 When installing a new lamp, reset the lamp hour and lamp
strike counters as described in "Time" on page 13.
