It's an evaluation of the lighting in your home using a professional spectrometer, which measures the full spectrum of each light source along with other key characteristics. Every assessment is performed by Jonathan Farrar, CRMI, Building Biologist, or a technician he has personally trained, and Jonathan reviews all findings.

Spectrum
We capture each light source's spectral profile to show how its output is distributed across the visible range, including the balance of blue and red wavelengths.

Color Temperature
We measure how warm or cool each light appears, which helps you match lighting to the time of day and how each room is used.

Color Rendering
We evaluate how naturally each light source shows colors compared with daylight.

Flicker
Many LED and fluorescent lights flicker at speeds you can't see. We measure flicker and identify which fixtures, bulbs, and dimmers perform best.

Light Levels
We measure brightness in key areas so you can plan for bright, functional daytime spaces and dimmer, warmer evenings.

A written report with:

1. Measurements for each light source evaluated

2. Comparisons between fixtures, bulbs, and dimmer settings

3. Prioritized recommendations for bulbs, fixtures, and controls

4. Guidance on daytime and evening lighting for bedrooms, nurseries, and living spaces

• Wanting healthier lighting in bedrooms and nurseries

• Eye strain or discomfort under certain lights

• Choosing bulbs and fixtures for a new build or remodel

• Evaluating screens, lamps, and specialty lighting

• Wanting data instead of marketing claims on packaging

Families, home offices, new construction and renovation projects, and anyone who wants their lighting to better support daily routines.

Light spectrometry is often added to an EMF assessment, since dimmers, LED drivers, and smart bulbs can affect both lighting quality and dirty electricity.
