The GembaRed UltraBright is our fantastic Cyan light for Bright Light Therapy!

We have finally gone off the rails on this one, our first non-red light product! We wanted a sturdy, simple, safe, and effective bright light to use indoors!

- Bright Lights help anchor circadian rhythm and sleep cycles.

- Cyan light (505nm) is safer than blue and gives great stimulation!

- 3rd Party tested high Lux light to be used in line with the science.

- Runs off of Direct Current (DC) adapter for low Flicker and Low EMF performance.

- 60 degree lenses and frosted diffuser to be gentle on the eyes.

- Sturdy floodlight style design!

The GembaRed UltraBright LED light finally delivers a high lux light in a simple and affordable design. Too often we see "bright light therapy" lamps that are under-powered and fail to deliver sufficient brightness at a meaningful distance away.

We choose to use Cyan light centered at 505nm. This wavelength is ideal to offer strong bright light while minimizing the potentially hazardous short-wavelength blue light.

In Red Light Therapy we usually discuss intensity. For Bright Light Therapy, we need to know the Lux - which is a measure of brightness. We had our 3rd party measure Lux accurately so it can be used properly and effectively. Similar to most Red Light Panels improperly measuring intensity and falsely claiming 100mW/cm^2, we feared that most "bright light therapy" lights aren't reporting Lux properly and are just saying 10,000 Lux just for marketing reasons.
