Why evening light matters

Most homes are lit for convenience, not biology.

After sunset, your body needs a different signal than what most lights produce. Our Circadian lighting fixes three problems at the source.

Blue lightStalls melatonin
Invisible flickerStrains the eyes
Dirty electricityElectrical noise

The benefits

What the right light gives back

Fall asleep easier

Blue-free evening light lets melatonin rise on schedule, so drifting off feels natural again.

Calms the nervous system

Warm, flicker-free light eases the low-grade stress that low quality, poorly designed LEDs put on your body.

More daytime energy

Blue-optimized Daylight in the morning sharpens your rhythm, so you wake clearer and stay alert.

Protects eye health

Zero visible flicker and no blue-light glare mean less eye strain, fatigue, and evening headaches.

The Solution

One light that follows the sun.

Flicker-free, low-EMF light with three settings you cycle with your existing light switch - clean Daylight by day, warm Sunset at dusk, and a blue-free Campfire glow at night.

Tap to change the setting

Blue-optimized • day

A bright, energizing setting for daytime tasks and getting ready.

Warm amber • evening

A warm amber glow that starts lowering blue light exposure as evening begins.

Zero blue • night

A fiery, candlelit glow that emits zero sleep-disrupting blue — lighting the room without breaking your rhythm after dark.

  • Flicker-free
  • No dirty electricity
  • Low EMF
  • No blue light

The science

The light frequency behind each setting

Spectrometer measured results of the spectral power distribution for our light settings. As the day winds down, the short blue and green wavelengths - the ones that suppress melatonin - drop toward zero.

Daylight

Blue-optimized for energy

Enough blue and green to stand up to midday sun - energizing, but warmer than a standard ceiling light.

Sunset

Reduced blue & green

A warm amber bridge to dusk - low enough in blue that it won't signal midday to your brain.

Campfire

Zero blue light

A fiery glow with no sleep-disrupting blue-light your room without disturbing your rhythm.

Specifications

A BR40 flood bulb with a standard E26 base, featuring our upgraded, revolutionary flicker-free and low-EMF LED technology.

Sync the lights on first install: Multiple lights operated by the same switch will need to be synchronized. Follow this procedure to do so: Make sure dimmer is at full brightness. Turn the lights off, wait 10 seconds, and then turn them on and off 3 times. On the 4th time turning the lights on, they should be synchronized.

Dimmer switches may vary in compatibility, potentially causing issues like unsynchronization. Please check compatibility before installation. For assistance, contact our support team or consult a qualified electrician.

Customer Reviews

Overall rating: 4.8 / 5 from 8 reviews.

I’m so happy with my purchase. The bulbs do exactly what they said they do. I wear a “Hume” band/tracker that tracks my sleep among other things. When looking at my REM sleep & deep sleep …..I seem to be hitting those areas more often and longer than light sleep I usually have. I have changed nothing but the bulbs throughout our house therefore it’s the bulbs that are working with me and I getting much more quality sleep. I will continue to purchase from this company. VERY happy with my purchase!

BR40 Circadian Lightbulb

We are using these for outside our garage shining on our driveway, it’s making our outside after dark experience sooo much calmer, especially when we let the dogs out and the motion sensed lights come on. This is much more gentle than normal lights! Thank you!!

BR40 Circadian Lightbulb

We like the warm glow of these bulbs. They set the mood for our family room. They remind me of a nice sunset.

BR40 Circadian Lightbulb

Bought the 8-pack of the 6 inch BR40 lights. They are awesome. Only downside is that one of the eight was faulty. As I screwed it in, the bulb fell off the base, seemed to sever some wires, and I had to use pliers to get the metal portion that screws into the housing out. The other 7 lights are fantastic, and actually pretty bright. Even with this one setback, I’d likely buy again.

BR40 Circadian Lightbulb

Much better We have 4 of these light fixtures in our living room but never turned on those lights because of the harsh blue light from the LEDs. These are a game changer. We did have a bit of an issue when we first put them in with two being one color setting and the other two being a different one, but they’ve finally synced back up. It’s nice to turn back on the overhead lights on occasion and not feel blinded.

BR40 Circadian Lightbulb

Love LOVE LOVE During a full-house remodel, I saw an Instagram ad for these health-focused LED bulbs and started digging into circadian rhythm research. The more I learned about how standard LEDs can disrupt melatonin production and sleep quality, the more concerned I became. Instead of sticking with the modern LEDs our builder originally planned, we made the decision to swap out all 33 fixtures in our home for these older-style, warmer, circadian-friendly bulbs. Yes, it was a significant extra expense and a bit of a hassle, but after living with them for a while, I can confidently say it was 100% worth it for my family’s sleep and overall health. No more harsh blue light in the evenings—everyone is sleeping better, waking up more refreshed, and the difference is noticeable. Highly recommend if you’re willing to invest in your long-term well-being.

BR40 Circadian Lightbulb

Worth every penny! These bulbs are absolutely perfect! I thought I would need a special light switch to access, the 3 different settings. I was willing to get them just to get rid of the flicker from the 16 overhead lights that light my living/dining/kitchen. I was happily surprised that I can get all 3 glows, and bonus that my family loves them too! Such a wonderful upgrade!

BR40 Circadian Lightbulb

Five stars! Love these light bulbs! I tested these with slow motion video and didn't see any visible flickering. Easy to switch between the settings. Still get plenty of light/brightness during the day and get the soft campfire tones for the evening hours. Will be purchasing more in the future to slowly transition the rest of our light fixtures over to circadian friendly lighting!

Frequently asked questions

What is Healthy Home circadian lighting and why do I need it?

Healthy Home circadian lighting is lighting designed to work with your body’s natural rhythm instead of against it.

Most standard bulbs are made to simply brighten a room, but they often contain harsh blue-heavy light, visible or invisible flicker, and low-quality internal components that can contribute to electrical noise. That may be fine during the day, but after sunset, your body needs a very different light signal.

Our Circadian Lightbulbs are made with upgraded LED technology that produces flicker-free light, has low-EMF output, and is designed to prevent dirty electricity. Each bulb has three color settings that can be cycled through using your existing light switch:

Daylight for bright, full-spectrum daytime light.

Sunset for a warm amber glow in the evening.

Campfire for a zero-blue, fiery glow at night.

The Circadian Night Light uses our signature Campfire setting in a standard plug-in design. It gives you a soft, warm light source for bathrooms, hallways, bedrooms, and children’s rooms, with 3 brightness levels and a darkness sensor that turns on automatically in the dark.

Together, they help you replace harsh nighttime lighting with warm, cozy, blue-free light that feels more like candlelight or firelight. The goal is simple: create a calmer home environment after sunset, support your natural wind-down routine, and avoid flooding your bedroom or hallway with bright overhead light at night.

How do I switch between the Daylight, Sunset, and Campfire settings?

Healthy Home lighting works with your existing light switch.

To change settings, turn the light off and back on within 8 seconds. Each quick off-and-on cycle moves the bulb to the next setting: Daylight, Sunset, or Campfire.

When the light is left off for more than 8 seconds, the bulb remembers the last setting used and turns back on to that same setting.

This makes it simple to use the same bulb throughout the day without needing an app, remote, smart home system, or separate fixture.

When should I use each light setting?

Use Daylight during the day when you want brighter, full-spectrum light for visibility, focus, cleaning, working, or getting ready.

Use Sunset in the evening when you want a warmer amber glow and less blue and green light exposure.

Use Campfire after sunset, before bed, or during nighttime wake-ups when you want the warmest, lowest-blue light possible.

A simple routine is: Daylight during the day, Sunset in the evening, and Campfire at night.

Can circadian lighting help with melatonin and falling asleep easier?

Light is one of the main signals your body uses to understand time of day.

Bright, blue-heavy light after sunset can interfere with the body’s natural melatonin rise, which is one of the signals that helps you feel sleepy and prepare for rest.

Healthy Home circadian lighting is designed to reduce the disruptive light signals commonly found in standard nighttime lighting. The Campfire setting removes blue light and creates a warmer, firelight-like glow that is better suited for evening and nighttime use.

This does not force sleep, and it is not a medical treatment. Instead, it helps create a calmer lighting environment that may support your body’s natural wind-down process and make it easier to transition toward sleep.

What makes Healthy Home lights different from regular bulbs, and other biohacker lighting?

Most standard bulbs are designed to brighten a room. They are not usually designed around circadian rhythm, evening biology, flicker, EMF, or dirty electricity.

Healthy Home Circadian Lightbulbs are different because they combine several features in one bulb:

Three light settings for different times of day: Daylight, Sunset, and Campfire.

Blue-light-free Campfire mode for nighttime wind-down.

Flicker-free light to avoid the rapid pulsing found in many standard LEDs.

Low-EMF output for a cleaner home lighting environment.

No dirty electricity design to reduce unwanted electrical noise from the bulb.

Standard screw-in design so you can use circadian-friendly lighting without installing tacky fixtures, red bulbs, strips, goggles, or complicated smart systems.

They are made to look and function like normal home lighting, while giving you a much healthier light environment.
