Experience infrared therapy the way nature intended with our proprietary FireLight® bulbs (formerly known as ThermaLight®). We spent years perfecting a spectrum that delivers near, mid, and far infrared, plus red light just like the sun—but with none of the harmful UV.

The bottom line: you get the best heat and light therapy in less time. Sweat faster, feel better.

• No harmful UV light
• No blue light
• No flicker stress
• Delivers 2–4x more red and near infrared wavelengths than competitors
• Mouth-blown stained glass made using ancient techniques

Note: Our stained glass bulbs are handmade and unique, which means they may have slight color variations that in no way affect performance. Each bulb goes through a strict quality control process to ensure your satisfaction.
