Introduction
The F35 is a DLP projector by projectiondesign out of Norway.
These have 2 easy-to-replace lamps, interchangeable motorized lenses with horizontal and vertical shift, and are built well enough to run in 24/7 use in places like museums and restaurants. If a lamp fails during operation, the projector will light up an LED to indicate which lamp has failed.
Lamps last 2,000 hours (2,500 in eco mode) and can be run in single or dual-lamp mode. These are UHP sealed mercury-vapor bulbs, so some cautions should be kept in mind regarding these lamps:
[ ! ] Be careful not to touch the protective glass when replacing the lamp, oils or other contaminants will create hot spots, and may cause the protective glass to overheat and break while in use.
[ ! ] Be extremely careful when removing the lamp module. In the unlikely event that the bulb ruptures, small glass fragments may be generated. The lamp module is designed to contain these fragments, but use caution when removing the lamp module.
[ ! ] In the unlikely event of a lamp rupture, a limited amount of mercury vapor may be released into the room. To avoid inhaling this vapor the room should be exited and ventilated for a period of at least 30 minutes.
Tools
-
-
Each lamp has a separate door. Unscrew the captive Philips screw at the top of the door and open it.
-
-
-
Observe there are 3 plastic thumbscrews per lamp -- two on top and one at bottom.
-
Rotate them 1/4 turn (90 degrees) counter-clockwise to unlock.
-
If they are difficult to turn by hand, a large flat-head screwdriver may also be used.
-
Once all 3 screws are unlocked, grasp the lamp housing from the rear protrusion, and pull. If you feel a lot of resistance, try wiggling the screws to ensure they have released.
-
Lamp hours are recorded on a chip in the lamp itself, so there should not be a timer to reset manually when installing a new lamp.
Compatible part numbers are:
400-0300-00 (GP3 UHP lamp, 250W) or 400-0500-00 (GP3 UHP lamp, 300W).
OEM lamps may be hard to purchase since the projectors have been discontinued.
Installation of new lamps is performed in the reverse order: insert lamp, lock thumbscrews, close doors and tighten each screw.
