Silk LED bulb mimics natural sunlight to help you live better

Silk by Saffron is a smart LED bulb that automatically adjusts its color temperature so you get light tailored to your circadian rhythm.

It goes without saying that our mood and general well-being are directly related with the light in our environment. Yet, the advent of artificial lighting and digital screens has wreaked havoc on our innate circadian rhythm throughout the years. With this in mind, the Saffron crew has developed an LED bulb that can actually sync to its users’ internal clocks to emulate the natural shifting color spectrum of the sun.


Called Silk, the smart LED is said to enhance performance and sleep patterns by providing users with the optimal kind of light over the course of a 24-hour period. Unlike other smart lights on the market today, this 800-lumen unit doesn’t require any management throughout the day. Once it’s turned on, Silk adjusts itself based on the sun and time, shifting from a midday’s cool blue intensity to a warmer, much more soothing tones for the evening.

“You’ve probably read up on the effects of late-night screen use, but the problem is much bigger than that since it extends to all the mundane everyday lights in our homes and offices too,” the Utah-based startup explains.

Each bulb has two banks of LEDs inside — one that contains cool colors and another with warmer hues — that mix together to create the right balance. Simply screw them into a lamp and overhead lights, then control them wirelessly from a central ZigBee bridge. Using Saffron’s unique nClick program, which allows for an existing light switch to control the bulb, a user can also toggle their Silk between dimmer/brighter and cooler/warmer settings with a single click, or via its accompanying app.


The Silk app, which is compatible with both iOS and Android devices, enables a user to create their own zone-based schedules and switch behaviors to meet the lighting needs of any given situation, whether that’s a morning yoga session or an afterwork dinner gathering.

Currently live on Kickstarter, Saffron is seeking $100,000 on Kickstarter. The only downside is that you’ll have to wait until January 2016 to get your hands on them.
