1.4 Lamp alignment
Every time a new lamp is installed in the fixture, it must be aligned with the optical system to ensure optimum even light output from the unit.
1. Install the new lamp (par. 1.3), close the fixture and switch it on
2. Connect the fixture to a lighting console.
3. Point the fixture at a flat surface (if possible white or light colored) at least three metres from the fixture.
4. Set the control channels to obtain a white beam. Then open the IRIS, set the DIMMER fully open, FOCUS correctly and do NOT
project GOBOS or COLORS.
6. Use screws 1, 2 and-3 to align the lamp until an evenly projected light beam is obtained, with no shadows or zones which are
brighter than others.
