COMPATIBLE LAMPS
The MX-4 uses the Philips CDM-SA/T (short-arc, tubular) 150W discharge lamp.
If desired, the GE Arcstream 150 may be substituted. Installing any other lamp may
damage the fixture.
To replace the lamp
WARNING! Wear safety glasses and allow the lamp to cool for at least 5
minutes before removing the lamp.
1Disconnect the fixture from power and allow it to cool.
2Remove 2 screws from the lamp-socket assembly with a Pozidriv #2
screwdriver. Remove the lamp assembly.
3Remove the old lamp from the socket.
4Holding the new lamp by its base (do not touch the glass), insert the lamp pins
squarely into the socket.
5 If your fingers touched the glass bulb, clean it with a clean, lint-free cloth
wetted with alcohol.
6Insert the lamp assembly carefully so that the lamp wires are clear of the fan.
Replace the screws.
To align the lamp
Realignment when changing the lamp may improve performance.
1Strike the lamp and shine the light on a flat surface.
2 Center the hot-spot (the brightest part of the beam) horizontally with small
turns of the top-left adjustment screw using a 3 mm Allen wrench.
3Center the hot-spot vertically with the bottom adjustment screw.
4If there is no hot-spot, adjust the reflector until the light is even.
