Do LED Lights Emit Infrared? Here’s What You Need to Know

Standard LED lights emit little to no infrared (IR) radiation — and that’s a major advantage for salons.

Why LEDs Don’t Emit IR:

1. How LEDs Work:
LEDs generate light through electroluminescence — a highly efficient process where electricity passes through a semiconductor to produce visible light. Unlike incandescent or halogen bulbs, which rely on heating a filament (and emit both visible and infrared light), LEDs focus almost entirely on the visible spectrum.

2. Minimal Heat Emission:
While LEDs can feel warm during use, that warmth comes from the internal electronics — not from radiated heat or infrared light. High-quality LED fixtures use heat sinks to dissipate this internal heat, preventing it from affecting the surrounding environment.

3. Specialized IR LEDs Are Different:
Yes, there are infrared LEDs used in remote controls or security systems, but these are specially designed for that purpose. The LED lights used in salons and general illumination are engineered not to emit infrared.

Why This Matters for Salons:

• No Heat-Driven Color Distortion:
  Infrared radiation from older lighting technologies can skew hair color — often adding a reddish cast. LEDs avoid this issue, ensuring true, accurate color rendering indoors.

• Cooler, More Comfortable Workspaces:
  Without IR emissions, LED-lit salons stay cooler — reducing stylist fatigue and creating a more pleasant experience for clients.

In short:
Standard LED lights are virtually free of infrared emissions, making them the smart choice for beauty salons where color accuracy, comfort, and consistency matter most.
