Beauty Angel Orange, Yellow, and Red Light Dose

This appears to be a study comparing the Beauty Angel “energizing light technology” (ELT) with red light therapy (RLT).

ELT uses a medium pressure bulb. RLT uses a low pressure bulb.

The only reference I can find to “Energizing Light Technology” is in Beauty Angel marketing material.

Beauty Angel is the brand of “red light therapy” found at Planet Fitness gyms.

“The effective active spectrums of Energizing Light Technology (= ELT) are created by the combination of newly developed high-pressure bulbs with specially coated filter glasses and unique glass reflectors. The combination optimizes the results of photo bio stimulation and creates a new light experience.” Sun Studio LA

Both ELT and RLT subjects experienced wrinkle reduction and collagen production compared to the controls.

ELT 1
611-650 nm, 8.5 J/cm^2 and 570-850 nm, 51.4 /cm^2

EL2 2
611-650 nm, 9.4 J/cm^2 and 570-850 nm, 49.3 J/cm^2

RLT 1
611-650 nm, 8.9 J/cm^2 and 570-850 nm, 15.5 J/cm^2

RLT 2
611-650 nm, 9.6 J/cm^2 and 570-850 nm, 16.8 J/cm^2

The study offers a chart that is compares ELT to RLT wavelength proportions, but I can’t understand it so I can’t report that here.

Simultaneous yellow, orange, and red irradiance achieved skin improvement whether with ELT or RLT type lamps.
