CrimsonWrap Features

Dual Wavelengths

The belt pairs 660 nm red LEDs with 850 nm near-infrared LEDs. You can run either wavelength on its own or run both together, depending on the mode you select.

Wrap-Around Fit

An elastic adjustable strap secures the belt around the lower back, abdomen, thigh, knee or shoulder. Because it wraps in place, your hands stay free during a session.

CrimsonWrap

Auto-Off Timer

A built-in timer counts down during each session and shuts the belt off on its own when the session ends, so you do not need to watch the clock.

One-Button Control

A single button cycles through red-only, near-infrared-only and combined modes. There is no pairing screen, no firmware update and no app account to set up.

Frequently Asked Questions

One press turns on the 660 nm red LEDs. Two presses switch to the 850 nm near-infrared LEDs. Three presses run both wavelengths together. The single button handles every mode.

They differ in wavelength. The red LEDs on CrimsonWrap are 660 nm and the near-infrared LEDs are 850 nm. The belt lets you choose either one or run both together.

The elastic strap adjusts to fit the lower back, abdomen, thigh, knee or shoulder. Wrap the belt around the area you choose and secure the strap before you start.

Connect the plug controller, which is region-matched at checkout, to the belt and an outlet. Wrap the belt in place, then press the power button once to start in red mode.

The built-in timer counts down once a session starts. When the session ends, the belt shuts off by itself, so you can stay hands-free and focus on whatever else you are doing.

The LED array gives off a low, steady warmth as a byproduct of producing light. The belt has no separate heating element, so this warmth is part of normal operation.

Wipe the inner surface with a damp cloth between sessions. A cleaning microfiber cloth is included. Do not submerge the belt in water. Store it in the soft carry pouch.

No. The belt works with its single button. There is no pairing screen, firmware update or app account, and the printed quick-start guide covers the basic steps.

The red light belt is wrapped around the chosen area and secured with the elastic strap. One press of the power button selects red, two selects near-infrared, three runs both, and the auto-off timer ends the session.

This infrared light belt set includes the dual-wavelength belt, an elastic adjustable strap, a region-matched plug controller, a soft carry pouch, a printed quick-start guide and a microfiber cleaning cloth.

CrimsonWrap: A Red Light Belt for Lower Back, Knee and Shoulder

CrimsonWrap is a red light belt that wraps around the lower back, abdomen, thigh, knee or shoulder and is held by an elastic adjustable strap, which leaves the hands free.

The LED array uses two wavelengths, 660 nm red and 850 nm near-infrared. The belt can be worn as a red light waist belt or as an infrared light belt on a knee. A single button cycles through red-only, near-infrared-only and combined modes. No app or pairing is needed.

An auto-off timer ends each session on its own. The inner surface is wiped with a damp cloth between sessions and is not submerged. The set for this red light belt adds a region-matched plug controller, a soft carry pouch, a quick-start guide and a microfiber cloth.

  • 660 nm red and 850 nm near-infrared LEDs
  • Elastic strap for several body zones
  • Region-matched plug controller
