Infinity Lights

AJ Guptill from Crosspoint Church in Fredericton, NB, Canada, brings us these cool lights inspired by infinity mirrors.

AJ came across a picture of an infinity mirror and thought it would be awesome to try making some for their stage. AJ realized that they only look good if you are standing directly in front of them and about 2ft away (not ideal for church situations). They had all these LED strips cut and glued to boards (seen in one of the pictures), so they had to figure out something to do with them that could be done in only a couple of days. While assembling one of the infinity mirrors, AJ realized that by changing the angle of the mirrors, he could make it seem like there were multiple LED strips, but still only using one. They decided to use that idea and ended up with a really cool result for a very small price.

For each “light”, they used a single 2ft+/- RGB LED strip, one piece of 1×2 (same length as strips), 2 pieces of mirror approximately 6-8 inches deep by the same length as your strips, silicone, hot glue, 4 channel wiring.

They already had the DMX decoders and power supplies to run the LED strips, so they did not have to buy those this time.

They found the spacing they wanted and framed everything up with 2x4s.

Understanding Infinity Mirror Stage Lighting

Infinity mirrors create a mesmerizing visual effect using two parallel mirrors with lights between them, producing the illusion of infinite depth. While traditional infinity mirrors work best for individual viewing, this innovative adaptation from Crosspoint Church demonstrates how the concept can be modified for stage environments where the audience views from multiple angles and distances.

The breakthrough insight came from adjusting the mirror angles rather than keeping them perfectly parallel. By tilting the mirrors slightly, the infinite reflection pattern becomes visible from a wider viewing cone, making it practical for church sanctuaries. This modification sacrifices some of the pure infinity effect for dramatically improved visibility across your entire congregation.

The materials used in this build are remarkably accessible. Standard RGB LED strips provide the illumination source, while simple 1×2 lumber creates the structural frame. The mirrors can be acrylic mirror sheets, which are lighter and safer than glass for overhead stage installations. Silicone adhesive provides durable bonding that withstands temperature changes from the LED heat, while hot glue offers quick initial positioning during assembly.

Construction Tips for DIY LED Light Fixtures

Building custom LED fixtures requires attention to both electrical safety and structural integrity. When working with LED strips, always calculate your total power draw and use appropriate gauge wiring. RGB strips typically draw around 4-6 watts per foot at full brightness, so plan your power supply accordingly with a 20% safety margin.

The mirror mounting technique shown here uses silicone adhesive for permanent attachment. Apply silicone in a zigzag pattern across the back of the mirror sheet, then press firmly onto the wooden frame. Use clamps or weights during curing to ensure full contact. For additional security, consider adding small L-brackets at the corners, especially if your fixtures will be hung overhead.

Wiring management makes the difference between professional-looking fixtures and amateur results. Channel your wires through the 1×2 frame to hide them from view. Use wire clips or staples designed for low-voltage wiring to secure cables without damaging insulation. Label your wires during assembly to simplify DMX addressing and troubleshooting later.

Pro Tips for LED Stage Lighting Projects

Power Supply Planning: Always use a power supply rated for at least 20% more wattage than your calculated maximum draw. LED strips can spike in current draw when displaying white at full brightness. Mount power supplies in accessible locations for maintenance, and ensure adequate ventilation to prevent overheating during long services.

DMX Control Basics: If you are new to DMX lighting control, start with simple 3-channel RGB controllers before advancing to complex addressing. Test each fixture individually before connecting the entire system. Document your DMX channel assignments for future reference, and always terminate your DMX chain with a terminator resistor to prevent signal reflections.

Safety First: When hanging fixtures overhead, use appropriate safety cables rated for the weight of your fixtures. Never rely solely on adhesive bonds for overhead mounting. Have a licensed electrician review your power distribution if you are unsure about electrical codes. LED strips operate at low voltage, but your power supplies connect to mains voltage, requiring proper grounding and protection.

Maintenance and Longevity: LED strips can last 50,000+ hours with proper care. Dust your fixtures regularly to prevent heat buildup, and check connections annually for corrosion or looseness. Keep spare strips on hand for quick replacement if sections fail. Store any spare strips in a cool, dry place away from direct sunlight to preserve the adhesive backing.
