Report on a computer-randomized double blind clinical trial to determine the effectiveness of the gaalas (830 nm) diode laser for pain attenuation in selected pain groups

What the authors concluded

82% of those who received real treatment in the total population reported effective pain relief, compared with 42% of those who were assigned to receive sham treatment.

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 900 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
