VL6C+ ™ SPOT LUMINAIRE USER MANUAL 45

Aligning the Lamp

The design of the VL6C+ optical system is based on an optimally flat field. A flat field is one where there is no

detectable hot spot.

After a new lamp is installed, it will be necessary to align the lamp to optimize the beam. Knobs located at the

luminaire’s backcap allow for adjustment.

Tools:

Screwdriver, #2 Phillips

To align lamp:

WARNING: Backcap and adjustment knobs will be HOT during lamp operation. Wear gloves and/or use

tools to prevent burns.

To align lamp:

Step 1. Power up luminaire and allow to warm up for at least ten minutes.

Step 2. Set intensity to 100%.

Step 3. Position beam on a white wall at a distance of 10' to 20'.

Step 4. Using control console, open beam size iris, set zoom for mid-range, and adjust for hard edge.

Step 5. At backcap, using vertical and horizontal knobs, adjust hot spot to center of beam

(Figure 4-2.)

Step 6. Using focus knob, adjust beam for flat field.
