Lamp adjustment

Warning! Adjust the lamp with the fixture cool. The fixture may become hot during adjustment, so

wear heat-resistant safety gloves.

As well as giving uneven projection, a significant hot-spot in the beam will focus extra heat onto optical

components and may cause damage that is not covered by the product warranty.

After fitting a new lamp, adjustment may be required to obtain an even beam.

To adjust the lamp:

1. If the fixture has been in use, douse the lamp but leave power applied. Allow the fixture to cool for at

least 30 minutes. If the fixture is powered off, apply power and allow the fixture to reset.

2. Set zoom to wide so

that it is easier to see

any unevenness in the

projection. Strike the

lamp and open the

shutter.

3. Aim the fixture at an

even surface and

make sure that no

further commands can

be sent by DMX.

4. See Figure 11. Turn

the three Torx 20 lamp

adjustment screws C,

D and E to obtain the

most even beam.
