Independent Testing

Helio Glow emits six wavelengths: 630, 660, 810, 830, 850, and 1064 nm, the values the body responds to. LightLab's spectrometer measured the corresponding peaks at 652, 669, 819, 841, 858, and 1078 nm, the expected 10-to-20 nm offset.

Total output divides almost evenly: 58.6 watts of red, 58.7 watts of near-infrared.

The 1064 nm wavelength reaches the deepest. It is where Helio Glow puts more output than most panels in this category, the wavelength that targets muscle, joint, and brain tissue.

Irradiance is how much light power reaches your skin, measured in milliwatts per square centimeter. It depends on how far you stand from the panel.

LightLab mapped Glow's irradiance across 231 measurement points at four distances. At the center of the panel, the readings were:

• 6 inches: 71.7 mW/cm²
• 12 inches: 75.0 mW/cm²
• 24 inches: 65.3 mW/cm²
• 36 inches: 49.4 mW/cm²

Total light power leaving the panel face: 125.8 watts.

Flicker is the rapid pulsing of an LED's light as the electronics convert wall current into the steady signal the chips need. You don't usually see it. Your eyes register it anyway, and high flicker is associated with eye strain and headaches.

LightLab measured Helio Glow's flicker against two independent standards, IEEE 1789-2015 and NEMA 77-2017. Both classified the panel as "Low Risk", with measured flicker at 0.8%. The light is, for practical purposes, steady.

Beam angle is how widely a panel spreads its light. Wide beams scatter into the room. Narrow beams concentrate the light where you stand.

LightLab measured Glow's beam angle at 18.7 degrees and field angle at 28.8 to 29.6 degrees. The light goes forward, toward the user, not sideways into the walls.

Helio Glow uses three internal cooling fans. Cooling extends LED life, but fans make sound.

In LightLab's noise-dampened chamber, Helio Glow measured a maximum of 43.3 decibels at full output. That is around the level of a quiet library or a refrigerator across the room.
