Maximize sunlight & supplement it with LED lighting.
It’s a fact — everyone loves to get out into the sun every once and a while. And as the weather continues to warm, we find staying inside harder than ever. But what if you could make the lighting in your office possess some of the health and feel-good benefits of sunlight? You can, with high-CRI LED Lighting and by designing a floor plan to include several sunroofs.
According to studies published in Lighting Research & Technology and Energy and Buildings, spaces featuring daylight-sensing controls can reduce the energy used for electric lights by 20–60 percent when utilized correctly.
But, natural lighting has more benefits than just conserving energy. According to Architectural Lighting Magazine, daylighting offers many aesthetic and health benefits, including increasing occupant productivity and comfort while providing the stimulation needed to regulate human circadian rhythms – or the internal body clock. According to Psychology Today, those who are exposed to natural light during work hours sleep an average of 46 minutes more per night than those who do not.
It’s well-known that LED bulbs boast long lifespans and consume less power than incandescent bulbs — sometimes as much as 90 percent less. And while LED bulbs come in a variety of brightness levels, including a daylight variation, multiple studies have shown natural light improves the mood and productivity amongst employees and high (90+) CRI LED Lighting with color temperatures ranging from 5200K – 6400K is the closest artificial lighting can come to natural sunlight.
The Similarities Between LEDs and Sunlight
Believe it or not, LED lights have a lot in common with sunlight. LEDs can mimic the hue and intensity of natural sunlight and help to maintain the human body’s natural circadian rhythm. This is because LED components allow for finer adjustments of color, brightness and intensity.
According to a recent article in The Wall Street Journal, some homes are being equipped with LED lighting that automatically mimics sunlight by changing from soft, warm amber in the morning to bright, cool white during the day and then back to amber in the evening. Researchers said this helps counteract the disruptive effect of conventional artificial lighting on the body’s circadian rhythms.
To execute daylighting correctly, excessive glare and temperature increases due to solar heat gain must be taken into consideration. Both of these factors can be detrimental to occupants if not handled correctly. Installing automated shades or dynamic glazing, which automatically tints to maximize natural light while reducing heat and glare, can curb these issues.

Talieh Ghane researches the interaction between light and health at the California Lighting Technology Center. We talked about the biological vs. visual system of light, how to synchronize your circadian clock for better health, how light is like a drug, and why you shouldn’t be on your phone right before bed (guilty).
A color rendering index (CRI) is a quantitative metric of the ability of an artificial light source (i.e. LED, Fluorescent, Halogen, Incandescent, etc.) to accurately reveal the colors of a subject in comparison to a natural light source. A CRI of 90 means that the artificial light source is replicating roughly 90% of the visible color spectrum that the sun would produce on the same color.
It is a truth universally acknowledged that store dressing rooms are every woman’s worst nightmare. The number one complaint voiced by women and men everywhere is that the lighting is harsh, glaring and reminiscent of the dentist’s chair or perhaps a police interrogation room (“No, officer, I did not realize that pairing Converse with Versace was a crime against fashion”).
Unlike wireless lighting systems like Wi-Fi, Bluetooth Mesh is designed for large collections of devices, numbering into the thousands. Switches, HVAC, sensors, light fixtures, and shades can communicate with each other by forwarding a message, or command, across all the devices in that Bluetooth chain until reaching the destination to perform said operation, (i.e. turn ON the 3rd floor office lights). The communication, instead of passing through your WiFi router, comes from the originating device and travels from light fixture to sensor, to AC unit, to any other chain of Bluetooth Mesh enabled devices, like a Bluetooth highway or a body’s central nervous system, until the command reaches the lights on the 3rd floor.
As architectural designs have digressed from symmetrical and parallel mirroring patterns that align with vaulted ceilings, grid axis, and more, linear lighting allows architects to highlight asymmetrical architectural features and lines (which is where the term “architectural lighting” comes from). The lighting design pattern of 2019 is no design pattern.
