Targeted Red Light + Heat — Knee
Solbasium Optix Red Light Knee Pad
The Optix Knee Pad combines three therapies in one wearable device — red light (633nm), near-infrared light (830nm), and adjustable heat (105°F, 109°F, 117°F) — designed to conform around the knee joint. The dual-wavelength pair targets tissue at two different depths: 633nm for skin and surface tissue, 830nm for deeper muscle and connective tissue penetration. Heat layers on top for circulation and joint relief.
Built for sore knees from training, general inflammation, or daily aches. Irradiance hits 20 mW/cm² for joint-specific dosing — calibrated for the smaller surface area of the knee compared to the Back Pad’s lumbar coverage. Three adjustable intensity levels let you customize each session. A built-in 15-minute timer handles session length automatically. The compression-style strap holds the pad snugly in place during use.
10,000 mAh rechargeable battery means no cord, no outlet, no tether — use it at home, at the gym, or wherever the knee needs work.

Triple Relief Technology
Three therapies, calibrated for the knee.
Red light, near-infrared light, and adjustable heat — running together through a single 15-minute session, with form factor and dose tuned specifically for the knee joint.
?Dual-Wavelength Red + NIR LightTwo therapeutic wavelengths — 633nm ± 5nm in the red range and 830nm ± 5nm in the near-infrared range. The 633nm targets surface tissue; 830nm penetrates deeper into muscle and connective tissue around the joint. Irradiance is 20 mW/cm², calibrated for the smaller surface area of the knee.633 + 830 nm · 20 mW/cm²?Three-Setting Adjustable HeatHeat layers on top of the light therapy with three adjustable intensity levels — 105°F, 109°F, and 117°F. Heat drives circulation around the joint and softens tight surrounding musculature. The combination of heat plus dual-wavelength light is the “triple relief” architecture shared across the Optix line.105°F · 109°F · 117°F

Inside the Pad
What the Knee Pad does differently.
Knee-Specific Fit
Designed to conform to the knee.
The Knee Pad is shaped to wrap the knee joint specifically — front, sides, and around the back of the patella — rather than sitting as a flat panel against the leg. The compression-style strap holds the pad snugly in place through movement or while sitting/lying. The form factor is what distinguishes it from the Universal Pad: same wavelengths, same heat settings, same battery size, but the shape is purpose-built for the joint contour.
- Conforms to the knee joint — front, sides, around the patella
- Compression-style strap — secure fit through movement
- Use sitting, lying, or moving — strap holds the pad in place
Knee-Conforming Compression StrapTriple Relief
Light + heat in one 15-minute session.
Two therapeutic wavelengths run simultaneously with adjustable heat for the full 15-minute session. The 633nm wavelength works on surface tissue and skin; 830nm penetrates deeper into the muscle and connective tissue around the joint. Heat selection (105°F, 109°F, or 117°F) lets you match intensity to the session — gentle warmth for daily maintenance, stronger heat for tight, sore knees after training.
- Dual wavelengths: 633nm ± 5nm (red) and 830nm ± 5nm (near-infrared)
- Irradiance: 20 mW/cm² — calibrated for joint-area dosing
- Three heat settings: 105°F, 109°F, 117°F
- 15-minute auto shut-off — no manual session tracking

The Knee Pad runs three therapies simultaneously through a 15-minute session. Red light (633nm) targets surface tissue, near-infrared light (830nm) penetrates deeper into the muscle and connective tissue around the joint, and adjustable heat (105°F, 109°F, or 117°F) drives circulation and softens tight surrounding musculature. The compression strap holds the pad snugly around the knee, and the device shuts off automatically after 15 minutes.The Knee Pad is shaped specifically to conform to the knee joint — wrapping front, sides, and around the patella. The Universal Pad is a flatter form factor designed to conform to any body part. Both share the same 633 + 830 nm wavelengths, the same three heat settings, and the same 10,000 mAh battery. The Universal Pad has higher irradiance (30 mW/cm² vs 20 mW/cm²). Pick the Knee Pad for joint-specific fit; the Universal for flexibility.15 minutes. The pad has a built-in 15-minute timer that automatically shuts the device off — no need to track time manually.No. The Knee Pad runs on a 10,000 mAh rechargeable battery — cordless operation, use it anywhere. Charge with the included charging cord.Yes. Three adjustable heat settings: 105°F, 109°F, and 117°F.
