We measure blue light, flicker and daylight throughout your home.
Then we tune it to your body's natural rhythm.
Light is the strongest signal that sets your body clock. A home light analysis measures the brightness, color temperature, blue-light content and flicker of your main light sources, plus how much daylight reaches the rooms you use most. We compare the results to circadian lighting research and the WELL Building Standard, then give you a room-by-room plan for brighter days and calmer, darker nights.
Spectral, brightness and flicker readings in the rooms where you live, work and sleep.
Spectral readings show how much melatonin-suppressing blue light your bulbs and screens give off.
Invisible LED flicker can cause eye strain and headaches. We measure it against IEEE 1789 guidance.
We map how much natural light reaches the rooms where you spend your mornings.
Bedroom and living-room brightness after dark, where the right changes help sleep the most.

Of daylight on Seattle's shortest day of the year.
Shorter melatonin duration measured after evening exposure to ordinary room light.
US adults don't regularly get enough sleep.
Of our time is spent indoors, mostly under artificial light.
Small, targeted changes to light can make a noticeable difference.
Bright, cool-white light in the evening can delay your body's release of melatonin.
Short Seattle days leave many people short on the bright morning light they need.
Often linked to glare, poor contrast or LED flicker you can't consciously see.
Home offices are rarely lit for focus during the day or for winding down at night.
Circadian lighting matches your indoor light to your body clock: bright, blue-enriched light in the morning and daytime, and dim, warm light in the evening. It supports alertness during the day and better sleep at night.
Yes. Research shows that evening exposure to ordinary room light can suppress melatonin and delay its release. Blue-enriched light has the strongest effect, which is why the color and brightness of your evening lighting matter.
Many LED bulbs and dimmers rapidly pulse their light output. Even when you can't see it, flicker has been linked to eye strain, headaches and reduced visual comfort. We measure it so you can replace the worst offenders.
Getting bright light early in the day is one of the most effective ways to support energy and mood when daylight is short. We show you where to add light and when. For seasonal affective disorder, talk with your doctor about light therapy.
Pricing depends on the size of your home and how many rooms and tests you need. Request an assessment and we will send you a clear, fixed quote before anything is scheduled. No surprises.
Usually not. Most homes get the biggest improvement from a few targeted changes: different bulbs in key rooms, smart scheduling and better use of daylight. We rank every change by impact.
Light analysis is launching across the Greater Seattle area. Join the priority list and we will reach out to schedule, or book a mold inspection today.
