Illumination & Lux Level Testing
Inadequate workplace lighting is a Factories Act non-compliance and a recognised accident and eye-strain risk — and it can hold up an occupancy certificate or a green-building rating. Auriga Research provides NABL-accredited illumination and lux level testing for factories, offices, hospitals, warehouses, cleanrooms, and commercial buildings across India, verifying compliance with IS 3646, NBC 2016, and the Factories Act 1948.
Illumination testing is performed on-site at client premises by the Bahadurgarh lab team — our NABL TC-7710 accreditation explicitly includes Site Testing for noise and illumination levels. This is a direct, named accreditation for on-site lux measurement. Trained technicians bring calibrated lux meters to your facility and take grid-based readings at working-plane height to calculate average illuminance, uniformity ratio, daylight factor, and glare.
Backed by the Arbro Group's analytical heritage — Arbro Lab since 1990, Auriga Research since 2007 — with NABL ISO/IEC 17025 accreditation, our reports include lux contour maps, uniformity analysis, and the IS 3646 / NBC 2016 comparison — accepted by State factory inspectorates, building authorities for occupancy certification, and green-building assessors (IGBC, GRIHA, LEED).
Illumination Testing Scope
Each measurement is mapped to its standard or assessment type so EHS, facility, and certification teams can match scope to the compliance requirement at a glance.
Workplace Lux Levels
Illuminance per IS 3646 (Part 1) Code of Practice — e.g. 300 lux general offices, 500 lux detailed work, 150 lux corridors.
Average & Uniformity Ratio
Average, minimum, and maximum illuminance with uniformity ratio (min/avg) across the measurement grid.
Building Code Lighting
Daylight and artificial-lighting requirements per the National Building Code of India 2016.
Statutory Compliance
Workplace illumination adequacy verification under the Factories Act 1948.
Green-Building Daylight
Daylight factor assessment for IGBC, GRIHA, and LEED certification.
Emergency Lighting
Emergency and egress lighting level verification.
Outdoor / Perimeter
Parking, pathway, and perimeter area illumination measurement.
Glare & Luminance
Glare assessment and luminance (cd/m²) measurement for visual-comfort evaluation.
Grid-Based Survey
Working-plane grid measurement (0.85 m for desks, floor level for circulation) for avg / min / uniformity.
Post-Retrofit Verification
Lighting performance verification after a lighting retrofit or layout change.
How It Works
Get a Quote & Site Plan
Share your facility type, floor area, number of zones / task areas, and the purpose (Factories Act compliance, NBC 2016 occupancy, or green-building certification). Your dedicated SPOC confirms the survey grid, the applicable IS 3646 levels, and the on-site schedule before the visit.
On-Site Survey
The Bahadurgarh lab team visits your premises with calibrated lux meters and takes grid-based readings at working-plane height across every zone, plus task-area, emergency, outdoor, and glare measurements as scoped. The survey is conducted under the NABL TC-7710 site-testing accreditation, and the measurement records are registered in YLIMS on return.
Analysis & QA Review
Measured values are analysed for average illuminance, minimum, and uniformity ratio, mapped to lux contours, and compared against IS 3646, NBC 2016, and the Factories Act requirement. Every result passes through a formal internal QA review and sign-off before the report is generated.
Receive Your NABL Report
Your NABL-accredited illumination report is delivered digitally within the committed turnaround time. Reports carry Auriga's NABL accreditation under ISO/IEC 17025:2017, include lux contour maps and the standards comparison, and are accepted by factory inspectorates, building authorities, and green-building assessors. Track status in real time through YLIMS.

Who Needs Illumination Testing
- Factories under the Factories Act 1948 needing periodic workplace illumination compliance checks.
- Pharmaceutical and food manufacturers needing controlled-environment and cleanroom lighting verification.
- Construction and real estate developers needing NBC 2016 lighting compliance for occupancy certificates.
- Green building projects pursuing IGBC, GRIHA, or LEED certification (daylight and lux criteria).
- Hospitals, diagnostic labs, and operation theatres with task-specific illumination requirements.
- Warehouses and logistics facilities verifying aisle and dock lighting for safety.
- Facility and EHS managers validating lighting retrofit or LED-conversion performance.
- Architects and MEP consultants verifying lighting design during building commissioning.
- Educational institutions and offices documenting workplace lighting for safety audits.
- Corporates building the illumination dataset for ESG / workplace-wellbeing disclosure.
Why Auriga for Illumination Testing
NABL TC-7710 site-testing accreditation for illumination
Our Bahadurgarh lab's NABL scope explicitly names Site Testing for noise and illumination — a direct, verifiable accreditation for on-site lux measurement, not a bench method stretched to the field.
On-site survey by the Bahadurgarh lab team
Trained technicians conduct the survey at your premises with calibrated lux meters under the accreditation — no third-party sub-contracting of the field measurement.
Reports against IS 3646, NBC 2016 & Factories Act
Measured values compared against all the references applicable to your facility, with lux contour maps and uniformity analysis built for inspector and certifier review.
Green-building ready (IGBC / GRIHA / LEED)
Daylight factor and lux measurement packages formatted for green-building commissioning and recertification submissions.
Pairs with noise and IAQ site testing
Illumination, noise, and indoor air quality can be surveyed in a single coordinated site visit — one mobilisation, one consolidated workplace-environment report.
Arbro Group analytical heritage
Established analytical heritage through the Arbro Group (Arbro Lab since 1990, Auriga Research since 2007), with NABL ISO/IEC 17025 accreditation — the audit trail EHS managers, facility teams, and MEP consultants look for in a site-testing partner.
