Changing the lens tube
Four different lens tubes with varying beam angles are available for the fixture. To change the lens
tube, refer to the diagram below:
1. Hold the front of the lens assembly with one hand so it cannot fall out.
2. Remove the thumbwheel screws on the top and bottom of the lens tube. The top screw also
has the focusing knob attached.
3. Slide the lens tube forward out of the fixture.
4. Slide in the new lens tube (1).
5. Replace the thumbwheel screws (2) and (3). For the top screw (2), ensure the focusing knob is
in place on the screw with the gear teeth on the underside. Rotate the focusing knob until the
gear teeth mesh with the bar on the lens tube housing.
6. Tighten the screws.
