Wind Down

Dimmable, warm Wind Down light bulbs simulate the soft glow of late afternoon light, minus the disruptive blue light that can interfere with restful sleep. You'll feel calmer and more relaxed as your body naturally unwinds and prepares for sleep.



Our exclusive Wind Down light spectrum is designed to help your body and mind naturally unwind in the evening. And, unlike regular LED's, our lighting is tuned to sync with your natural circadian rhythms.

  • For use in lamps and lighting fixtures
  • Ideal for rooms you use primarily during evening hours


Most modern lighting contains too much blue light which suppresses the sleep hormone, Melatonin. Or, it’s too bright and stimulating for evening use. The National Sleep Foundation recommends using the right type of light at sun down, to allow your body to unwind, relax, and naturally prepare for sleep.

            Wellness Specs
            • Melanopic/Photopic Ratio (M/P): 0.45
            • Circadian Stimulus (C/S): 0.167 @ 150 lux
            • Flicker Sensitivity (PST): Less than 0.7%
            • % of Blue Light: ≤ 0.83%
            • Energy Star Certified 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.

            THE RIGHT LIGHT <small> to help you naturally unwind</small>

            THE RIGHT LIGHT to help you naturally unwind

            Modern living has us surrounded by low-quality, stimulating indoor light. Receptors in our eyes ingest this light, which in turn disrupts our sleep cycles. And new research shows that people exposed to the wrong type of light after sundown tend to have a harder time falling asleep, have less REM sleep, and wake up feeling sleepier. That’s why we designed our Wind Down bulbs with a light spectrum tuned to reduce stress, promote relaxation, and help the body naturally unwind.

            Wind Down A19 LED Light Bulbs

            For Best Results

            Think of Brilli like a vitamin that supplements your sunlight exposure. You will notice some benefits immediately, and some over time. 

            • Wind Down bulbs should be used throughout the evening. You should begin to experience the benefits after 20 minutes.
            • Make sure you're within 10 feet of the light so it comes in contact with your eyes.
            • Use Wind Down bulbs at the dimmest setting for a more relaxing effect.
            • All lighting in the room should be the same. For example, don't use Charge Up and Wind Down lights together.

            Changing the world,
            ONE LIGHT AT A TIME

            Through our partnership with Watts of Love, every Brilli purchase brings light to a community that lacks access to resources
            like electricity, education and economic independence. Because we believe that light
            is vital to life, and that light should shine equally on all.
