Early versions of our devices used LEDs of a single wavelength. Different wavelengths were tried over time, but in the early cases each device featured LEDs of a single type (and therefore wavelength).
John’s research planted the idea that multiple wavelengths could improve the outcomes being achieved, so we started making devices with two or more types of LED.
