Lighting Calculators
From early-stage concept work to final checks, these tools give you fast, accurate lighting data.
Explore energy use, carbon impact, lighting levels, and compliance details in a way that supports real-world commercial projects.
Smarter lighting starts with better data
Our lighting calculators and technical tools are designed for architects, lighting designers, engineers, and facilities managers who need fast, reliable data to support commercial lighting decisions.
Each tool is built around industry standards — including CIBSE, BS EN 12464-1, BS 5266, and TM65/TM66 — giving you the same level of clarity you’d expect from a leading lighting manufacturer.
Whether you’re validating emergency lighting coverage, estimating energy savings, specifying colour temperatures, or reviewing circularity data, these tools help you make defensible, compliance-ready decisions at speed.

Professional Lighting Resources
Professional lighting decisions rely on accurate data. These calculators and tools provide a quick way to validate light levels, estimate savings, review compliance, and benchmark sustainability before committing to a design or upgrade.
By combining CIBSE guidance, BS standards, and manufacturer-verified performance data, each tool simplifies a previously complex part of the specification process.
Whether you’re designing an office fit-out, auditing an industrial facility, reviewing circularity scores, or mapping emergency lighting coverage, the tools support you with clear, defensible outputs.
Use these tools to:
• Calculate required lux, lumens, and uniformity for common commercial applications
• Review CIBSE’s recommended lighting levels across a range of environments
• Verify emergency lighting spacing and compliance for BS 5266
• Check carbon reductions, energy savings and payback periods
• Compare colour temperatures and RAL finishes for design consistency
• Access TM65 and TM66 data for embodied carbon and circularity assessments
• Explore layout and performance considerations for office, warehouse, hotel, and industrial projects
Every tool has been developed by Lumenloop — a UK manufacturer specialising in commercial, architectural, and industrial luminaires.
Designed around real lighting design workflows, they allow specifiers and engineers to gather the insights they need without opening modelling software.
