CHROMOPHARE^® Lighting Systems

Frequently Asked Questions

Q: My CHROMOPHARE Light is slowly moving from where I placed it. How do I prevent this from happening?

A: CHROMOPHARE Lights are equipped with friction brakes, located at each moveable joint, which can easily be tightened to prevent "drift" of the light. Note which joint is moving and adjust the brake screw as shown below.

Brake Adjustments (horizontal arm, spring arm, cardanic joint, light head)

Note: All brake adjustments (drift) are clockwise to tighten, counter-clockwise to loosen.

1. The movement of the horizontal arm can be adjusted using a slotted screwdriver (Fig. 1)

Q:The bulb in my CHROMOPHARE Light has burned out. How do I replace it?

A: BERCHTOLD CHROMOPHARE Lights are designed for ease of bulb replacement. Follow the instructions below. Bulb Replacement (Fig. 12)

1. Loosen the large knurled screws that hold the light handle assembly to the lighthead and pull the light handle assembly from the light head (Fig. 12)
2. Check the silver decal on the green circuit board located on the back of the light handle for the correct bulb part number
3. Pull the burned out bulb from the holder. (check for broken filament to determine which bulb is dead)
4. Install new bulb. The bulb can be installed in either direction. IMPORTANT: Do NOT touch bulb with fingers as skin oil will cause early bulb failure.
5. Re-install the light handle assembly and tighten knurled nuts with fingers.
