Circadian Rhythm Lighting in Orange County
Lighting that follows the sun indoors — warm at sunrise, crisp daylight-white at midday, and warm again by evening — automatically, every day of the year.
Your body keeps time by light. Over the course of a day, natural daylight changes color: warm and amber at sunrise, cool and bright at midday, warm again toward sunset. The body's internal clock — the circadian rhythm — takes its cues from that shift, which is why a bright blue-white screen at midnight feels so wrong.
Most homes ignore it completely. A conventional LED is one fixed color from morning to midnight, so the kitchen at 9 PM is lit exactly like the kitchen at noon. Circadian rhythm lighting — also called human-centric or tunable-white lighting — brings the daylight curve indoors.
The fixtures change both color temperature and brightness through the day, on a schedule tied to the real sunrise and sunset at your address. Nobody presses anything. The house simply looks right, and feels right, at every hour.

The daylight curve, brought indoors
Color temperature is measured in Kelvin. Low numbers are warm — 2700K is the golden tone of sunrise or a classic incandescent bulb. High numbers are cool — 6500K is the crisp, slightly blue white of open sky at midday.
We program your lighting to follow that curve: 2700K at 6 AM, rising to 4600K by 9 AM and a crisp 6500K at midday, then easing back through 4600K at 3 PM to a warm 2700K by 6 PM. After sunset the light keeps warming and dimming into a low, comfortable evening glow.
Because the schedule follows the actual sun rather than a fixed clock, it moves with the seasons on its own — later sunrises in December, longer days in June — without anyone ever adjusting it.
How we accomplish circadian rhythm lighting
Circadian rhythm lighting is a system, not a light bulb. It takes the right fixtures, a control platform that can drive them, and a design built around how your household actually lives.
1. Tunable-white fixtures
It starts with the fixture. Circadian rhythm lighting needs tunable-white LEDs — fixtures with warm and cool emitters that blend anywhere across the range. A standard LED can't do it, no matter what controls it. We specify recessed, accent, and decorative fixtures built for tunable white, with strong color rendering at every point on the curve.
2. A control system that speaks color
The fixtures are driven by a lighting control system that commands color temperature as well as brightness, running on an astronomic clock that calculates sunrise and sunset for your exact location every day of the year.
3. A curve designed room by room
Not every room should run the same curve. Kitchens, offices, and baths get the full daylight range. Bedrooms warm earlier and stay dimmer. Theaters and media rooms step outside the curve entirely while a movie is playing.
4. Night modes
After bedtime, motion-triggered pathway lighting comes up at a low, warm amber — enough to see the hallway or the bathroom at 2 AM without a blast of full-brightness white.
5. On-site tuning
After installation we tune the curve on site at morning, midday, and evening, then adjust it to your routine — early risers, late nights, work-from-home offices, and kids' bedtimes.
6. Overrides that behave
Keypads still work exactly the way you expect. Press a scene and the room does what you ask. Return it to automatic and it rejoins the curve wherever the day happens to be.
What a properly engineered system gets you
Mornings that feel like mornings
Cool, bright light through the morning and midday supports daytime alertness — the same signal natural daylight gives you outdoors.
Calmer evenings
Warmer, dimmer light after sunset is widely understood to be easier on your natural sleep-wake rhythm, and it makes a home feel calmer after dark.
Night light without the glare
Low amber pathway lighting for late-night trips, instead of switching on full-brightness overheads.
Rooms that look their best
Warm evening light flatters wood, stone, fabric, and skin tones; crisp daylight-white shows true color when you need it.
Completely automatic
Tied to sunrise and sunset at your address, so it follows the seasons without anyone touching a keypad or an app.
Efficient by design
Tunable-white fixtures are LED, and the curve runs lower brightness through the evening when you need less light anyway.
From first walkthrough to a system you actually use
High-ticket work goes wrong when nobody explains what happens next. Here is exactly how a project runs, start to finish.
- 01
Consultation
We walk the property with you, listen to how you actually live in it, and look at what's already there. No pitch — we're establishing scope, constraints, and what's realistic.
- 02
Design & proposal
You get a designed system with a written proposal: what goes where, what it does, what it costs. Theaters include a 3D model so you see the finished room before anything is built.
- 03
Installation
We coordinate with your builder, electrician, and designer, and we work clean. Cable is run properly, racks are built to be serviced, and the site is left tidy every day.
- 04
Programming & calibration
Scenes are built around your routine and tuned on site, after dark where it matters. Video is calibrated, audio is measured. This is the step that separates a system from a pile of equipment.
- 05
Training & support
We sit down with the household and make sure everyone can drive it — not just whoever ordered it. Then we stay reachable, with remote monitoring on supported systems.
Circadian Rhythm Lighting, answered
Straight answers to what people actually ask before starting a project like this.
What do 2700K and 6500K actually mean?
They're color temperatures, measured in Kelvin. 2700K is warm and golden, like sunrise or a traditional incandescent bulb. 4600K is a neutral white. 6500K is the crisp, cool white of midday daylight. Circadian rhythm lighting moves smoothly between them over the course of the day.
Can I use my existing light fixtures?
Only if they're already tunable white, and most aren't. Standard LEDs are one fixed color, so circadian rhythm lighting usually means new fixtures in the rooms where it matters most. It doesn't have to be every room.
Can I add it to just a few rooms?
Yes, and that's where most clients start — typically the kitchen, the home office, and the primary suite. The rest of the house can stay on standard lighting control and be added later.
Will it work with the lighting control system I already have?
It depends on whether your platform can control color temperature, not just brightness. Many current systems can; older ones often can't. We'll check what you have before recommending anything.
Can I turn it off or override it?
Always. Any keypad scene overrides the curve for that room, and you can set a room to stay at a fixed color temperature permanently if you prefer.
Is circadian rhythm lighting a medical treatment?
No. It's a lighting design approach that follows the natural pattern of daylight, and many people find it makes their home more comfortable. It isn't a treatment for sleep or health conditions — for those, talk to your doctor.
What clients say
“I had the pleasure of working with Ashkan on multiple AV installations in the past 10+ years. His team performed a complete update of the media room which includes a multi-screen projection home theater, music server, whole house audio, dedicated 2Ch HiFi system, as well as Crestron automation for AV, lighting & shades. The most recent project is a second HT AV system for the family room/kitchen remodel. It's a complex installation & we're very happy with the job. Ashkan is always professional, responsive & reliable with excellent after sales/installation supports. Highly recommended.”David NgOrange County · Home theater & whole-house audioVerified Google review
“I have worked with Ashkan Baghaee for over seven years. He and his team installed and since have maintained the AV, WiFi, and camera systems at our house. They at all times have been effective, professional, and responsive. I have recommended Ashkan to numerous neighbors, friends, and relatives, and those who have worked with him have provided very positive reports. I will continue to recommend Ashkan to anyone in need of his services.”Don DickersonOrange County · AV, WiFi & camerasVerified Google review
“I have worked with Ashkan for 3-4 years. He did a extensive AV job on our Newport Beach home. He did a great job. In addition, as with any extensive AV job/project they'll be a need for follow up. Ashkan has always made himself available and been quick to help with any AV issues. A Pro from start to finish and he will stay with you to make sure your happy. Highly recommend”Mike MNewport Beach · Whole-home AVVerified Google review
