Independent, 3rd Party Testing by LightLab International

Helio Glow emits six wavelengths: 630, 660, 810, 830, 850, and 1064 nm. LightLab measured the peaks at 633, 660, 809, 828, 852, and 1066 nm. To the body that is the same light and few nanometers either side makes no difference. Researchers treat anything within about 3 to 5 nm as bioequivalent wavelengths.

Measured 6 inches from the panel, the red channels deliver 68.60 watts of light, and the near-infrared channels deliver 81.26 watts.

The 1064 nm wavelength reaches the deepest. It is where Helio Cure puts more output than most panels in this category.

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. The highest readings were:

• 6 inches: 98.87 mW/cm²
• 12 inches: 93.25 mW/cm²
• 24 inches: 81.89 mW/cm²
• 36 inches: 61.59 mW/cm²

Total light power captured 6 inches from the panel: 141.11 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. IEEE 1789 classified the panel as "Low Risk", its safest category, with modulation at 0.64%. Under NEMA 77, measured flicker was 0.3%. 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 16.9 degrees and field angle at 27.5 to 27.7 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 40.0 decibels at full output facing the panel. That is around the level of a quiet library or a refrigerator across the room.
