Lamp Adjustment - Futurelight PHS-250 Pro-Head-Spot Manual Del Usuario

Before replacing the lamp, unplug mains lead and let the lamp cool down (approx. 10 minutes).
During the installation do not touch the glass-bulbs bare-handed! Please follow the lamp manufacturer's
notes!
Do not install lamps with a higher wattage! Lamps with a higher wattage generate temperatures the device
was not designed for. Damages caused by non-observance are not subject to warranty.

Step 2: Unscrew the knurled-head screws of the lamp holder and remove it.
Step 3: If replacing the lamp, remove the old lamp from the lamp holder.
Step 4: Insert the lamp into the lamp holder.
Step 5: Replace the lamp holder and tighten the knurled-head screws.
Step 6: Adjust the lamp as described under lamp adjustment.
Step 7: Replace the lamp cover and tighten the fixation screws.

Lamp adjustment

Do not operate this device with opened cover!
The lampholder is aligned at the factory. Due to differences
between lamps, fine adjustment may improve light performance.
Strike the lamp, open the shutter and the iris, set the dimmer
intensity onto 100 % and focus the light on a flat surface (wall).
Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws "A, B, C". Turn one screw at a time to drag
the hot-spot diagonally across the projected image. If you cannot
detect a hot-spot, adjust the lamp until the light is even.
To reduce a hot-spot, pull the lamp in by turning all three screws
"A, B, C" clockwise ¼-turn at a time until the light is evenly
distributed.
If the light is brighter around the edge than it is in the center, or if
light output is low, the lamp is too far back in the reflector. "Push"
the lamp out by turning the screws "A, B, C" counterclockwise
¼-turn at a time the light is bright and evenly distributed.
