36 MAC 2000 Performance II
Lamp replacement
Important! Do not touch the quartz bulb with bare fingers.
The lamp can be replaced with either a Philips MSR 1200
SA/DE GOLD (Martin P/N 97010310), or an OSRAM HMI
1200 W/S (Martin P/N 97010304). Both lamps are available
from your Martin dealer.
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 9. 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 in place.
3 See Figure 10. Pull the retention spring on the left-hand
end of the lamp socket up and then swing the end of the
lamp out. Pull the other end out of the socket.
4 Inspect the socket for corrosion (see “Replacing the lamp
socket” on page 36) and replace if necessary.
5 See Figure 11. 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.
6 Lift the lamp assembly so that 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.
7 When installing a new lamp, reset the lamp hour and lamp
strike counters as described in “Time” on page 14.
Replacing the lamp socket
The lamp holder used in the MAC 2000 Performance II
eventually wears out due to the high voltages that pass
through the contacts.
Wear begins to show up as discoloration at the contact
surfaces. When this happens, resistance increases and the
lamp becomes harder to strike. If this process is allowed to
continue, the lamp is likely to fail prematurely.
Each time the lamp is replaced, inspect the lamp holder
and have it replaced by a qualified technician as soon as
there are signs of discoloration or pitting at the contact
surfaces. We recommend routine replacement of the
socket after maximum 4000 hours of use (replace one
socket for every five lamps). Damage caused by failure to
replace a worn and/or discolored lamp holder is not
covered by the product warranty.
