Color Filter Wheel Overview
An FLI Color Filter Wheel provides the basis for uncompromised images night after night without fail.
Each traditional style FLI Color Filter Wheel is precision engineered with a highly accurate stepper
motor and chain drive. The large diameter pivot pin and bushing are precision ground and matched
for smooth, quiet no-fuss operation. FLI Color Filter Wheels use no internal lights for homing to
protect your images from stray light interference. Our traditional Color Filter Wheel line has six
different body styles that hold either round of square filters in various sizes as described in Table 1.
The Color Filter Wheel product number identifies the body type and the number of filter cups. Hence,
a CFW-3-10 has a body type 3 and holds 10 filters.

Product Safety
This FLI Color Filter Wheel is shipped with a 12-volt power supply. Do not use any other power supply
with this System or use the power supply in a way other than described in this Guide as it may cause
damage to the Color Filter Wheel that will not be covered under the warranty.
If you are concerned about lightning strikes in the area in which you use your Color Filter Wheel,
you may want to take safety precautions as electrical surges can damage electrical equipment. We
recommend that when your Color Filter Wheel is not in use that you unplug the Color Filter Wheel
from power and unplug the USB cable from the Color Filter Wheel.
