4" Slim Circadian LED Downlight

• Melanopic/Photopic Ratio (M/P): 0.43 to 0.90
• Circadian Stimulus (C/S): 0.16 @ 150 lux to 0.33 @ 300 lux
• Flicker Sensitivity (PST): Less than 0.7%
• % of Blue Light: 1.6% to 3.52% 
• Energy Star rated for energy efficiency

1) All Brilli lighting is designed with the optimal Circadian Stimulus (C/S) depending on time of day.
C/S was developed by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute. This metric indicates how well a one-hour exposure to a light source producing a certain light level and wavelength of light stimulates the circadian system, based on its ability to suppress the hormone Melatonin. Exposure to a 0.3+ C/S is effective for Melatonin Suppression, which is ideal for day time use.

2) All Brilli lighting is designed with the optimal Melanopic/Photopic (M/P) ratio depending on time of day.
Melanopic vision is the biological impact of light. Photopic vision the amount of light we typically experience during the day in a well-lit space. Our A higher M/P score (above 0.8) means the light is more stimulating and better for daytime use. A lower M/P (below 0.5) score means the light is less stimulating and better for night time use.

3) Brilli Wind Down bulbs have only 0.83% blue light, and Get in Sync fixtures (at the low setting) have 1.6% blue light.
Certain wavelengths of light suppress Melatonin in humans, with the strongest response occurring in the short-wavelength portion of the blue spectrum between 446 and 477 nm. This light is good by day, as it promotes energy, focus and alertness. However, there is consensus in the healthcare community that exposure to cool blue light should be minimized beginning 2 hours before bedtime, at a percentage of less than 2%, as anything higher inhibits Melatonin production.

4) All Brilli lighting has a Flicker Percent of less than 1% at 50Hz.
Flicker is the visible change in brightness of a lamp due to rapid fluctuations in voltage and power supply. Many individuals are sensitive to flicker, which can cause health risks like eyestrain and headaches. UL (the Global Safety Science organization) identifies “Low Flicker Risk” as a Flicker Percent of less than 8% at 50Hz and less than 10% at 60Hz.

5) All Brilli lighting is designed for optimal visual comfort.
Visual comfort is a reaction to the quantity and quality of light within a given space. It encompasses a variety of aspects, such as aesthetic quality, ambience, luminosity and absence of glare. The physiological aspect of visual comfort has three main factors – light source, distribution of light within a space (color, intensity) and how the light is perceived (harsh, soft, dull, sterile, etc.)

6) All Brilli lighting contributes toward satisfying Features #53, #54, and #58 under the WELL Building Standard®.
The WELL Building Standard® is a performance-based system for measuring features of the built environment that impact human health and well-being through air, water, nourishment, light, fitness, comfort, and mind.

7) All Brilli lighting is designed with multiple types of LEDs to simulate the effects of sunrise and sunset.
Lighting is very nuanced, and even the smallest differences matter. Multiple LED’s allow us to provide the right spectrum of light at the right time of day for well-being.

8) All Brilli lighting uses premium phosphors to deliver the most robust light spectrum to improve well-being.
Most LEDs use inexpensive phosphor to reduce costs, which decreases the quality of the light they produce.

9) All Brilli Get in Sync products offer patent-pending synchronized tuning, which changes both the color and intensity of the light when you move the dimmer.
Brilli follows the rules of natural sunlight – from bright, cool and crisp by day to soft, warm, and amber by night. The shift in color and intensity helps to ease our bodies into night mode, making the shift from go-go-go, to just go with the flow.
