How can I add a glass shield to a reflector?

This guide will show you how to add a glass shield to an HPS reflector, which can be adapted for various types of reflectors. Adding a glass shield can help protect the reflector and improve its performance.

Materials and Tools​

To complete this project, you will need:

  • Reflector with HPS
  • Pliers
  • Sidecutter
  • Philips screwdriver
  • 5mm drill bit
  • 4 bolts
  • 4 L-shaped brackets
  • Ruler
  • Electric drill
  • Isolating band (rubber/elastic tape)
  • Glass piece

Choosing the Right Glass​

Measure the dimensions of your reflector to determine the size of the glass piece you'll need. Hardware stores and window shops can usually cut any type of glass to your specifications. Choose between tempered glass (high heat resistance, thin, light, and more expensive) or regular plate glass (lower cost but may crack under high heat).

Step-by-Step Instructions​

1. Drill Holes in the Reflector​

Using the electric drill and a 5mm bit, drill four holes in each corner of the reflector.

2. Prepare the L-Shaped Brackets​

Cut the isolating band in half with scissors. Wrap the halved isolating band around each L-shaped bracket to create a soft surface that will protect the glass from scratches and vibrations.

3. Attach the Brackets and Bolts​

Use the Philips screwdriver to attach the L-shaped brackets and bolts to the reflector.

4. Insert the Glass​

Carefully slide the glass piece into the reflector, making sure it rests on the brackets. Maintain a 1.5-inch (4 cm) gap between the glass and the bulb.

Final Thoughts​

Once you've completed these steps, your glass-shielded HPS reflector should look polished and be ready to use. With proper preparation, this project can be completed in about an hour.
