The mathematics of light.
Reality, visualised.
We build physically accurate light distributions, engineering-grade lighting calculations and 3D GLDF digital prototypes that match lux meter readings on site.
From the mathematical model of the optics to genuine visual comfort in the finished building.
A standard calculation vs the KMK premium approach
Grab the divider in the middle and drag it with your mouse or finger to compare:
IES/LDT files with any beam angle (from 3° to 120°), including asymmetric beams, framing optics, oval distributions and louvres.
Illuminance checked on calculation surfaces and at individual points. Projects delivered to Russian GOST standards with a full documentation set.
GLDF digital prototypes with real spectra, multiple light sources, rotatable modules and gobo filters.
Everything the KMK-Photometry studio can do
Beyond calculations and 3D models we publish expert research, develop lighting engineering tools and consult on projects.
Lighting calculations and IES/LDT libraries
A carousel of 18 optical distribution models, GLDF digital prototypes with an interactive viewer and online questionnaires.
Completed case studies and lighting concepts
Museums, penthouses, architectural facades and industrial sites, each with a detailed breakdown of the photometric decisions.
A knowledge base on lighting design and photometry
In-house engineering articles on the mathematics of optics, illuminance formulas and the GLDF standard. Published in Russian.
A quick estimate for your project
Seven simple steps: type of space, floor area, available input data and the level of detail you need.
A philosophy of mathematical precision
Code compliance and detailed, high-quality visualisation are not mutually exclusive
