ThermoLab A Series vs S Series: Which Red Light Panel Is Right for You?
A Series vs S Series: The Key Difference
ThermoLab makes two professional red light therapy panel ranges. Both deliver red and near-infrared light therapy, but they're built for different primary goals. A Series: clinical-grade, 5-wavelength therapy with pulse mode and Wi-Fi. S Series: maximum irradiance for full-body recovery at the highest power outputs available for home use.
The A Series: 5 Wavelengths, Pulse Mode, Wi-Fi App
The A Series (A60 to A320) uses five wavelengths simultaneously: 630nm, 660nm, 810nm, 830nm, and 850nm. This multi-frequency approach covers more biological targets than any standard dual-wavelength panel.
- 630nm — Surface skin renewal and collagen support
- 660nm — Core red light for skin and superficial tissue
- 810nm — Near-infrared penetrating to 5–10mm
- 830nm — Anti-inflammatory for joints and muscle
- 850nm — Deep near-infrared for circulation and deep tissue recovery
All A Series panels include pulse mode, Wi-Fi app control, and a free stand. From the A60 at £289.99 to the A320 at £899.99.
The S Series: Maximum Power, Dual Wavelength
The S Series (S1000 to S5000) uses 660nm and 850nm — the two wavelengths with the deepest clinical research base — at power outputs from 1000W to 5000W. The S Series optimises for irradiance intensity: the density of light energy per square centimetre. Higher irradiance means more photons reaching target tissue per second, critical for effective full-body sessions.
From the S1000 at £499.99 to the S5000 at £1,899.99.

Which Should You Choose?
Choose A Series if skin renewal, anti-ageing and clinical multi-wavelength therapy are your main goals — or if you want pulse mode and app-controlled sessions.
Choose S Series if athletic recovery, DOMS reduction and maximum irradiance across a large body area are your focus — or if you're setting up a home gym, studio, or clinic.
