- The listing specifies 380 LEDs and wavelengths of 460nm, 660nm, and 850nm.

## Before you buy

- The listing describes the LED arrangement as 380 LEDs and gives 65W power output, but does not provide irradiance or other measured light-output data. Treat wavelength and output figures as listing claims, not verified measurements.

## A good fit for

- People seeking a home-use mat for targeted coverage across more than one body area.
- Buyers who want adjustable intensity, session timing, and pulse modes.

## Less suited to

- People seeking a mat explicitly sized for full-body coverage.
- Buyers who need published irradiance measurements or independently verified performance data.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the four- or five-star categories, but a smaller share is two- or three-star. With no written customer feedback supplied, the ratings do not establish what buyers liked or disliked. For buyers considering the stated 38 × 16-inch format and adjustable controls, the ratings alone cannot confirm coverage or light-output performance.
