How to Test for LED Flicker at Home
While spending time indoors, at one point or another you’ve likely encountered a flickering light. Flashing on and off like a strobe or disco ball, it can be supremely annoying, but it can also even be dangerous. Why does flicker occur? To some degree, flicker happens in all light sources with an AC power supply […]
5 Scientific Facts You Need to Know About Blue Light
We know that blue light impacts our sleep, but to what extent? Blue light disrupts the circadian cycle by suppressing the production of melatonin at bedtime, for example, but it can also help mitigate sleep deprivation in the morning. The studies listed below are just a few examples of the vast literature available in the […]
The Blue & Black Dress Effect: Lighting & Apparel
Selecting the right lighting for a retail store is important. Whether it’s accent, ambient, or general lighting, the lights and fixtures you choose can change how customers perceive the paint color of a room, the tint of an item in a store window, or the color of a striped dress—from blue and black to white […]

As it turns out, the blue light filter that turns your iPhone screen an orange hue isn’t actually helping […]
Part 3: Picking the Brain of a SORAA Scientist Aurelien David
In the final section on LED design, learn about the difference between lumens and lux, the introduction of Wi-Fi and Bluetooth technologies into LED, what exactly “efficiency droop” means, and some insight into the future of LED. We spoke about color previously, but what is color temperature? Color temperature describes whether the light “feels” warm […]
Why Understanding R9, not Just CRI, Matters to You
How do you explain color, and more precisely how do you explain correct color versus incorrect color, because doing so matters when it comes to understanding light and your objectives. For example, retailers have a lot to consider when choosing the right type of light for showcasing their products – they want the products to […]
Blue Free Light: What You Need To Know
There’s been a lot of discussion in technology and health news about how blue light, the light from your mobile phones and TVs and LED lighting, wreaks havoc with our circadian rhythm and makes it difficult to fall asleep at night.

Chronobiology and the Fascinating Science that Drives Our Lighting Design
Light—especially daylight—is incredibly important to our health. It helps regulate our natural 24-hour diurnal clock, or our circadian rhythm, which tells us to wake with the rising sun and to get ready for sleep when the sun sets. When we lack enough sunlight—or if we’re exposed to too much—some health problems could arise, primarily in […]
Part 1: Picking the Brain of a SORAA Scientist Aurelien David
LEDs are the way of the future. There’s no denying that. They’re affordable, they lower your energy costs, they last longer than other types of bulbs, and they’re more environmentally safe. But if you’re ever wondered about the technology behind LEDs and how they work, this article is for you. We’ve thought up every detailed […]
Part 2: Picking the Brain of a SORAA Scientist Aurelien David
This section is all about colors and crystals. We’ll find out how LEDs create certain colors, what goes into the creation of crystals, and learn all about GaN-on-GaN. Can you explain how LEDs use crystals? What’s the process behind creating them? When they hear crystal, most people may think of shiny diamonds. Actually, a lot […]
