Easily align lighting with the time of day:
🔹 Morning Shine: 6500K | EML >1500 lux
🔹 Daytime transition 4000K | EML >500 lux
🔹 Evening Calm: 3000K | EML <50 lux
🔹 Deep Sleep: 3000K | EML <10 lux
Activity-Based Presets (Place horizontally on the working plane)
Simplify commissioning with ready-to-use targets:
🔹 Gathering: 350 lux | 4000K | EML >150 lux
🔹 Reading: 400 lux | 3500K | EML >200 lux
🔹 Working: 500 lux | 4000K | EML >200 lux
🔹 Meditation: 150 lux | 3000K | EML >50 lux
🔹 Education: 500 lux | 4500K | EML >200lux
🔹 Meeting: 400 lux | 4000K | EML >200 lux
🔹 Relax: 250 lux | 3000K| EML >100 lux
🔹 Greeting: 600lux | 5000K | EML >150 lux
Uniformity Made Easy
Automatically generates lux, CCT, and contrast uniformity — ensuring balanced lighting across spaces.
Continuous Monitoring and Smart Integration
Track min, max, and average lux with adjustable scan times, and connect seamlessly to building automation systems.
Lighting designers can also use In. Licht Pro for fast, reliable on-site measurements. Paired with In. Licht Well, it provides complete environmental monitoring.
If you’re a Lighting Designer, Manufacturer, WELL AP Consultant, or Quality Control/Inspection professional, In. Licht Ultra is the right tool for you.
It measures light across the spectrum, illuminance, and frequency—providing all the essential parameters your project requires:
Key Measurements
Illuminance, CCT, CRI (including R1–R15 values, Ra or Re), CIE (x, y), Duv, Spectrum, Dominant Wavelength, Peak Wavelength, Peak Intensity, TM-30 (Rf and Rg), SDCM
Complete Human-Centric Lighting Parameters
Circadian Action Factor, Equivalent Melanopic Lux (EML), Melanopic Equivalent Daylight Illuminance (M-EDI), S/P Ratio, Blue Hazard Ranking, Circadian Stimulus
Flicker Risk Measurement
Percent flicker, flicker index, frequency, and SVM—plus a visual flicker indicator light for easier flicker detection
Spectrum Comparison
Compare the spectra of different fixtures to evaluate light sources side by side
Step-Shot Measurement Function
Capture multiple points with a single click. Lux, CCT, CRI, EML, and M-EDI are recorded on one page and downloadable as a CSV report—ideal for design verification
Certified “Works with WELL”
Supports WELL Certification and Performance Verification.
🔹 Can be handheld, placed flat, or mounted on a panoramic tripod at 45 cm above table height—specifically designed for WELL performance verification.
🔹 Generates Quality of Light reports (PDF) and spectrum data (CSV) for documentation and verification.
New Companion App – Ultra Color Quality
Performs light quality assessments based on China’s New National Standard for White Light Color Quality, including Color Preference (MCPIr), Color Discrimination (CDMr), and CIE-Rf values and levels
One Device, Three Applications
🔹 Fixture Quality: Position the spectrometer close to the light source in a dark, controlled environment.
🔹 Ambient or Task Lighting: Place the spectrometer horizontally on the working plane.
🔹 Light Environment / Human-Centric Lighting: Position vertically at 1.4 m from the floor (~45 cm above tables).
In. Licht Ultra – New Companion App for Light Quality Assessment
China’s New National Standard for White Light Color Quality
Color Fidelity Index (CIE-Rf)
🔹 Ensures that the appearance of objects under artificial lighting closely resembles their true colors under natural light.
🔹 Similar in purpose to TM-30 Rf.
🔹 A comprehensive metric that compares the color appearance of 99 standard test color samples under the test light source and a reference illuminant.
Color Preference
Reflects perceptual preference—how pleasing colors appear under the light, such as making fruit look fresher or skin tones appear more natural.
🔹 Absolute Colour Preference Index (MCPI) : Indicates overall color preference under the test light source, derived through meta-analysis. Evaluates across different correlated color temperatures (CCTs).
🔹 Relative Colour Preference Index (MCPIᵣ) : The percentage ratio of the absolute MCPI of the test source to that of the reference source. Used for comparison under the same CCT.
Color Discrimination
Indicates the eye’s ability to distinguish subtle color differences—critical for applications like artifact restoration or medical diagnostics.
🔹 Absolute Colour Discrimination Metric (CDM) : Measures discrimination ability under the test light source across various CCTs.
🔹 Relative Colour Discrimination Index (CDMᵣ) : The percentage ratio between the CDM of the test light source and the reference illuminant. Useful under the same CCT.
The standard classifies performance into grades for easier understanding and specification.
➡️ Use relative indices (CIE-Rf, MCPIᵣ, CDMᵣ) for comparisons under the same CCT.
Whether you are preparing for WELL certification or simply care about creating a healthy living environment, In. Licht Well is a device worth considering. It transforms environmental health from a subjective feeling into scientific, measurable, and trackable data.
In. Licht Well provides continuous monitoring, data logging, and long-term tracking to support a healthier and happier environment, with visible indicator lights for quick and intuitive feedback.
