Lighting is a magic wand for an onyx stone. If the lighting is uneven and you have expensive stone that looks patchy. Here are a few tips to achieve a flawless high-end glow:
A. Choose the Right Light Source
- LED Panels: For an even glow without any bright dots, always use an ultra-slim LED panel. They give uniform distribution across the complete slab design.
- LED Strips: A budget-friendly option is onyx. You need to install them in a dense grid pattern to avoid shadows.
- CCT Adjustable Lights: Always use LEDs that allow you to switch between warm white and cool white to highlight the intricate veins.
B. Maintain the “Golden Gap”
Do not stick the light directly to the back of the stone. Always leave a gap of 2 to 6 inches between the light and the onyx. The space allows the light to spread and diffuse, creating a soft, ethereal glow rather than harsh lines.
C. Use a Diffuser
If you are using LED strips, then place a milky acrylic sheet between the light and the stone. This acts as a diffuser and ensures the light hits the onyx evenly.
D. Accessibility is Key
Never seal the lights permanently. It should be serviced regularly. LEDs can last for years, but if a driver or a strip fails, you should be able to replace them without breaking the marble.
