Lighting is very nuanced, and even the smallest differences matter. 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.ħ) All Brilli lighting is designed with multiple types of LEDs to simulate the effects of sunrise and sunset. 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.)Ħ) All Brilli lighting contributes toward satisfying Features #53, #54, and #58 under the WELL Building Standard®. It encompasses a variety of aspects, such as aesthetic quality, ambience, luminosity and absence of glare. Visual comfort is a reaction to the quantity and quality of light within a given space.
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.ĥ) All Brilli lighting is designed for optimal visual comfort. Many individuals are sensitive to flicker, which can cause health risks like eyestrain and headaches.
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.Ĥ) All Brilli lighting has a Flicker Percent of less than 1% at 50Hz.įlicker is the visible change in brightness of a lamp due to rapid fluctuations in voltage and power supply. This light is good by day, as it promotes energy, focus and alertness. A lower M/P (below 0.5) score means the light is less stimulating and better for night time use.ģ) Brilli Wind Down bulbs have only 0.83% blue light, and Get in Sync fixtures (at the low setting) have 1.6% blue light.Ĭertain 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. Our A higher M/P score (above 0.8) means the light is more stimulating and better for daytime use. Photopic vision the amount of light we typically experience during the day in a well-lit space. Melanopic vision is the biological impact of light. Exposure to a 0.3+ C/S is effective for Melatonin Suppression, which is ideal for day time use.Ģ) All Brilli lighting is designed with the optimal Melanopic/Photopic (M/P) ratio depending on time of day. 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. Energy Star rated for energy efficiencyġ) All Brilli lighting is designed with the optimal Circadian Stimulus (C/S) depending on time of day.Ĭ/S was developed by the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute.Flicker Sensitivity (PST): Less than 0.7%.Circadian Stimulus (C/S): 0.53 760 lux.
