We recommend the Sleep Sanctuary so you can create a consistent light environment that your body can actually respond to — instead of a single bulb working against all the other lights in your environment.
Most people start with their bedroom environment or wind-down space – the difference is immediate.
Some go further — and change their entire home, transforming how they live.
Why has nothing else worked for your sleep so far?
Most sleep solutions focus on you "doing more".
The Better Sleep Bulb transforms the environment your biology responds to.
That’s why it works — even if nothing else has.
Very grateful this product is now available. We need it for better health. In a few years, and with proper education, these health bulbs will be standard in homes and officers.
Appreciate you sharing this Dan, we completely agree. We look forward to releasing other fixtures/fittings soon to make wide-spread adoption the reality.
I bought a 6-pack and installed them in all of my family's bedrooms. My two children, wife, and I are all sleeping better!
We're so glad to hear this Emanuel. We know that they work particularly well for young children!
I found this to be the perfect light for day and night. I've been testing it mainly in my daughters bedroom and will soon purchase more for the rest of the house!
Thanks Daniel. We look forward to supporting you in further spaces throughout your home!
I like these bulbs even more than I expected. They do seem expensive at first, but they make my nighttime circadian practice so convenient now. And what’s convenient for me is much easier to follow through with.
Thank you so much, Kendra. You've put your finger on exactly why we built the bulbs: a circadian practice only works if it's easy enough to actually keep up, night after night. So glad they've made yours feel effortless. Really appreciate you supporting our mission at In Rhythm! Best wishes, Dan (Co-Founder)
These bulbs are almost perfect… the evening and night settings are incredible and were exactly what i was hoping my other circadian bulbs would be… but the day time setting is so dim :( the daytime color is perfect, just not bright at all. My small bedroom is so dark during the day with 4 of these bulbs on daylight settings. I’ve had to use my plant light for extra light. The evening and night settings are fantastic though. Dim and a great color. My other circadian bulbs from a different company were like bright yellow and the same brightness level as the day setting. I wish i could combine their daylight setting with In Rhythm’s evening and night settings. These are soooo close to being perfect. Fingers crossed for a brighter daylight setting in the future
Thank you, Taylor, for such a thoughtful and detailed review. Insights like yours are exactly what help us make the bulbs better, so we really appreciate you taking the time to share them. It's wonderful to hear that the evening and night settings are just what you'd hoped for, and we completely understand the frustration with the daytime brightness, especially in a small bedroom that doesn't get much natural light.
The good news is that our 2nd generation bulb, launching by the end of October, introduces a new, brighter Day Plus mode designed for exactly the situation you describe, and we've also increased the brightness and functionality of the Evening mode.
Thank you again for sharing this so clearly. We hope the 2nd generation earns that fifth star from you very soon!
Really appreciate you supporting our mission at In Rhythm! Best wishes, Dan (Co-Founder)
Excellent product, used every day, got 5 of them in action. Looking forward to availability in other formats like E14.
Thank you Martin, this is brilliant — five of them going every day, we're so glad to hear you're making the most of them! Good news too: we've got more fixtures launching soon, so hang tight, as other formats are on the way. Really appreciate you and thanks for being part of In Rhythm! Best wishes, Dan (Co-Founder)
Love it...thank you so much
Aw, thank you so much Linda — this means a lot! So happy you're loving it, and thanks for being part of In Rhythm! Best wishes, Dan (Co-Founder)
These bulbs are great. I have them in my office and use full spectrum during the day and when I work into the evening I change the settings to reduce blue light so I have a better sleep. My son noticed them and asked for some for his room so I ordered some for his room as well. Highly recommend.
Love this so much, Nathan. Full spectrum by day and dialling down the blue light in the evening is exactly how we hoped people would use them, and the fact that your son wanted them for his room too just made my day. Thanks for the recommendation and for being part of In Rhythm! Best wishes, Dan (Co-Founder)
Great alternative to heinous LEDs, we use In Rhythms for reading actual books and they've been a game changer for optimizing circadian health.
Ha, 'heinous LEDs' — couldn't have said it better myself! So glad In Rhythms have earned a spot by your reading chair, and that you're feeling the circadian benefits. Thanks so much for the support and for being part of In Rhythm! Dan (Co-Founder)
Started feeling the difference after the first night...a sense of calm and quiet. Now I need all of my overhead lights replaced :)
This is amazing to hear. That sense of calm after the first night is exactly what it's all about, and yes, replacing those overheads next is a very good idea! Thanks so much for sharing this and for being part of In Rhythm! Dan (Co-Founder)
I just bought the light bulbs recently after learning all the ways it could impact my nervous system and I have to say I am quite delighted by the feeling of calm I have in the evening now!
Very glad that the bulbs are doing exactly as they should! Thanks for the feedback Karina.
What the world needs now—great sleep!
Thank you for this great product!
Thanks for your feedback and support!
Love it - have been using circadian aligned bulbs for years and this one is great! It's suitable for all human beings, which you can’t say for most bulbs!
Hey Mollie. Thank you for sharing this. It’s great to hear how the light is influencing your environment and how you feel. Small shifts like this can have a powerful effect over time. This feedback means a lot coming from you; we know you’re very experienced with these kinds of products! Thanks for the support. Best wishes, Dan (Co-founder)
My evenings feel noticeably calmer. When the sun goes down and I switch the bulb on, the warm light helps my body shift into wind-down mode. It’s easier to relax, read, and settle into sleep without feeling wired late at night. Before this I was using a red bulb at night because I was already trying to be mindful of circadian lighting. The Better Sleep Bulb feels more natural and comfortable though. It creates a softer environment that still supports winding down in the evening. I’d describe it as simple lighting that supports your natural rhythm and helps create a relaxed environment before bed.
Hey Kris. We appreciate this feedback! That sense of calm is what we were aiming for and it’s great to hear it's coming through in your experience. Thanks for the support. Best wishes, Dan (Co-founder)
It's a good bulb, but the instructions for using it are not that clear online.
Hey Tedd. Thank you for this feedback. we have now built out a how to page that will accompany all future orders to ensure that you and all other customers receive clear instructions on how the bulb works! Thanks for the support. Best wishes, Dan (Co-founder)
The better sleep bulb is a game changer, especially in the evening. I’m able to have enough light to actually see what I’m doing, but it’s dim enough to not disturb my sleep. The color it puts out is soooo much better than other “circadian friendly” bulbs on the market!!!
Hey Sydney. It’s great to hear your sleep is improving! Thanks for the support. Best wishes, Dan (Co-founder)
I notice that the Better Sleep Bulb is emitting a very soothing light spectrum. I'd recommend it to anyone looking to improve their sleep quality while still having sufficient light, without the potential negative health effects associated with blue light exposure.
Thanks for sharing this Pam! Better sleep is exactly what happens when light supports your natural rhythm. Thanks for the support. Best wishes, Dan (Co-founder)
I was already using circadian-friendly bulbs, but this better sleep bulb is excellent! I originally had two different lamps in my bedroom: one with an amber bulb and one with a red bulb and had to switch between the two depending on timing. Now, I only need this one bulb for all situations!
Hey Valerie, thanks so much for sharing this. Better sleep is exactly what happens when light supports your natural rhythm! Thanks for the support. Best wishes, Dan (Co-founder)
It has helped start a more consistent evening routine. Once the light is on it is a constant reminder to start to wind down for the evening, come off tech, and start to get ready for a great nights sleep.
Hey Adam. Great to hear your sleep is improving with the use of the bulb. Aligning your evening light with your biology can make a real difference. Thanks for the support. Best wishes, Dan (Co-founder)
Since switching to the Better Sleep Bulb I’ve noticed a significant difference in how relaxed I feel in the evenings. Using the Night setting 1–2 hours before bed has become a game changer for my wind-down routine — my body genuinely feels like it’s being signalled to slow down and prepare for sleep. It’s made my evenings feel so much calmer and much more intentional. I also don’t have anxiety about having my light on in the early hours of the morning when I’m up at 4:30am and getting ready for gym because I know my body isn’t being exposed to harsh blue light.
Emily, thank you so much for this feedback! Thanks for the support. Best wishes, Dan (Co-founder)
The house feels calmer overall using this bulb. I climb in bed and read to my two boys, and they can barely last longer than a page or two, then they fall asleep. We're all sleeping so deeply. I usually use blue blockers and some red lamps around the house, but I love the option to have different spectrums throughout the day. I also really appreciate the deep orange tone over red. It just feels more natural. I think everyone can use the Better Sleep Bulb, but especially those with insomnia or trouble falling asleep. Nothing has been more important on my health and healing journey than a good nights' rest.
Hey Sara. Wow, I loved reading this feedback! So glad that all the family are benefitting. Thanks for the support. Best wishes, Dan (Co-founder)
This bulb makes for a much calmer atmosphere.
That sense of calm is what we were aiming for Annelie. Great to hear it's coming through in your experience. Thanks for the support. Best wishes, Dan (Co-founder)
It's making evenings much calmer, and in the mornings I'm feeling more rested - it’s a game changer.
Hey Cam. That sense of calm is what we were aiming for — great to hear it's coming through in your experience brother. Thanks for the support. Best wishes, Dan (Co-founder)
I love the light and how simple it is. To be very honest I haven't noticed any changes per se as I was using smart lights before and my evenings are pretty calm and sleep is good, But i really love the colours of the bulb and that there's no flickerin g(I didn't notice the flickering with the smart lights, but i'm sure it's there). I'd recommend it to everyone who's using normal lights. I can see the difference it will bring to people still using normal lights and how calming it is and I can see the positive impact it will bring to their evenings and sleep.
Really glad you're feeling that shift Carolina. Creating a more calming evening environment is exactly the ethos behind our current and future products! Thanks for the support. Best wishes, Dan (Co-founder)
I'm experiencing more calm nights, better sleep quality and finding it easier to fall asleep.
That sense of calm is what we were aiming for Vanessa. Great to hear it's coming through in your experience. Thanks for the support. Best wishes, Dan (Co-founder)
