Smart Circadian Lighting
By Dr. Meg Christensen | Updated January 2026
Smart circadian lighting systems automatically adjust color temperature throughout the day to support your natural rhythms—bright blue-rich light in the morning for alertness, warm amber tones in the evening for melatonin production. Set it once and let your lighting work for your health.
Oasis Adaptive Lighting System
Oasis offers several different layers of bulbs— ambient lighting, standard bulbs, and candle bulbs, that all sync with the sun, changing brightness and warmth automatically throughout the day. I appreciate that they intentionally create atmospheric lighting, which helps your home feel a lot cozier than using “the big light,” especially in the evenings. This is a nice, full house set-up, and it’s one of the only ones that doesn’t require you to use a third party app to program on your own—it comes with its own app that you can set up once and then let run for years.
Dyson SolarCycle Circadian Rhythm Lamp
Dyson’s SolarCycle lamps regulate blue light by automatically adjusting their color temperature based on the time of day and your location, mimicking the sun. This is especially useful for your office, where you work over the course of 8 hours — it simulates a sunrise in the morning, giving you bright blue light for focus, and softens and warms as it gets closer to evening. Also has a boost mode that gives you 20 minutes of bright intense light for when you need to focus. Dyson also offers a floor lamp version that can be used for circadian lighting anywhere in the home.
TUO Smart Circadian Light Bulb
Created with the Neuroscience department at the University of Washington, this light bulb (and optional base) is really special— it mimics dawn in a way no other adaptive lightbulb does, with alternating violet and orange hues (that looks like regular light, don’t worry.) This wakes you up and regulates your circadian rhythm, even during the winter, much better rather than the standard blue-enriched high-intensity bulbs. I even made a short TikTok video about this in 2025, and am excited to see there’s a light bulb that supports this advanced research now! Controlled with an app, this helps you wake up, but also has active and calm modes for the rest of the day.
Healthy Home App-Free Circadian Light Bulbs
Healthy Home is unique for two reasons— first, it’s app-free, and second, the types of circadian bulbs it offers are advanced and include recessed lighting. You don’t even have to change any wiring to access all three modes (morning, afternoon, and evening)— the bulbs are cleverly designed to cycle through them with quick switches of your existing light switch, and come equipped with a memory function so you don’t have to do it every time you turn the lights off. Smart! They also have blue-free night lights, standard size circadian light bulbs, and are a good, app-free choice.
