Lamp fitting and adjustment
1.
Disconnect the fixture from AC power. Allow the fixture to cool down for at least 15 minutes. Put the Tilt lock-catch in
the horizontal position.
2.
Dismounting the lamp (see below): remove the top cover of the shell first, and then the bulb cooling fans. Press down
the springy retainer by one hand and push up the lamp by the other (see below 1 and 2). Then you can easily take out
the lamp.
3.
Installing the lamp (see above): press down the springy retainer against, then carefully insert the lamp inside (see above
1 and 2). Fasten the screws and install the cooling fans as well as the cover shell.
4.
Make sure the new bulb is installed in the right position on the holder and the mounting holes are fixed, and the midline
of the lamp is aligned with the center point of the effect assembly (consisting of the rotating gobo wheel, static gobo
wheel, color wheel, strobe, prism, and frost), focus module, and object lens.
Notes
The fixture uses OSRAM SIRIUS HRI 440W S featuring low power consumption and high performance with a stable 7000K(
±
300) color temperature. Its average life span is 1500 hours.
Warning
Fitting another type of lamp will cause potential damage to the fixture. Change the lamp before it reaches its lifespan. Read
the guidelines in the package carefully when fixing the lamp.
To avoid any impact on the beam, do not touch the bulb with your bare hands. The lamp must be kept clean with the use
of the clean paper contained in its package.
