How to Focus Xenon HID Bulb for Non-Adjustable Focused Spotlights
***Spotlights Manufactured before August 2018***
Focusing a Spotlight is like concentrating the Sun’s Beam with a Magnifying Glass, like you did when you were a kid burning your name into a piece of wood. By moving the Globe in or out of the Globe Holder, you can broaden/tighten the Beam to the desired output. All of our Powa Beam HID and Quartz Halogen models are Hand Focused before they leave the Factory, so the only time you would need to focus a Globe would be during replacement of a blown Globe.
The best way to focus a Bulb is to shine the Spotlight on a wall about 10m away and look at the pattern of light that it is showing. The images below show different patterns that can occur, and how to fix them to get the optimum Spot.
Make sure to keep your fingers off the Globe by using a cloth or cardboard when moving it, if you accidently touch it during focusing then use Metho to clean it. Also be careful as the globe can get very hot.
To adjust the bulb position:
- Follow our directions on how to remove your reflector safely
- Use a 2mm Allen Key to wind in/out the grub screws on the side of the aluminium bulb holder to shift the bulb position
- Note that the longer grub screws are for adjusting left/right and the shorter screws are for adjusting up/down
WARNING: The Globes are Fragile. Gently ease them into the Globe Holder. Do not use any sideways force, otherwise the Globe might break. Do not over tighten screws.
