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).

How It Works

1

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.

2

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.

3

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.

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.

Frequently Asked Questions

What is lux level testing and why is it required?
Lux level testing measures illuminance (light intensity on a surface) using calibrated digital lux meters. The Factories Act 1948 mandates adequate lighting in workplaces to prevent accidents and eye strain. IS 3646 (Part 1) specifies recommended illumination levels for different work areas — 300 lux for general offices, 500 lux for detailed work, 150 lux for corridors. The National Building Code of India 2016 (NBC 2016) and green building certifications (IGBC, GRIHA, LEED) also specify minimum daylight and artificial-lighting requirements.
Is illumination testing done on-site, and which Auriga lab performs it?
Illumination testing is performed on-site at your premises by the Bahadurgarh lab team — our Bahadurgarh Environmental & Industrial Monitoring Laboratory holds NABL accreditation (TC-7710) whose scope explicitly includes Site Testing for noise and illumination levels. This is a direct, named accreditation for on-site lux measurement, not a lab-bench test extended to the field. Trained technicians bring calibrated lux meters to your facility, take grid-based measurements at working-plane height, and the accredited report is issued from the Bahadurgarh lab.
Which standards and lighting levels apply — IS 3646, NBC 2016, and the Factories Act?
Three references apply together in India. IS 3646 (Part 1) — Code of Practice for Interior Illumination — gives the recommended lux levels by task and area. The Factories Act 1948 makes adequate workplace lighting a statutory requirement, enforced by the State factory inspectorate. The National Building Code of India 2016 (NBC 2016, the current edition that superseded NBC 2005) sets daylight and artificial-lighting provisions for the building as a whole, and is referenced for occupancy certification. Auriga reports the measured levels against all the references applicable to your facility and use case.
Where is illumination testing typically conducted?
Illumination testing is conducted on factory production floors, in warehouses, offices, hospitals, laboratories, cleanrooms, educational institutions, retail spaces, and outdoor areas including parking lots and pathways. Measurements are taken at working-plane height (typically 0.85 m for desks, floor level for circulation areas) on a grid pattern to calculate average, minimum, and uniformity ratios across the space, with separate task-area readings where higher levels are required.
How often should illumination surveys be performed?
The Factories Act requires periodic illumination surveys as part of workplace safety audits — typically annually. Green building certifications (IGBC, GRIHA, LEED) require lux measurements during commissioning and recertification. It is advisable to retest after any lighting retrofit, after a significant layout or partition change, after lamp ageing / fitting replacement, or whenever occupants report visual discomfort or glare.
What is the regulatory consequence of inadequate workplace illumination?
Inadequate lighting is a recognised workplace-safety non-compliance. Under the Factories Act 1948, the factory inspector can issue an improvement notice or initiate prosecution for inadequate illumination, which contributes to accident risk and occupational eye strain. For building occupancy, an NBC 2016 lighting shortfall can hold up the occupancy / completion certificate. For green-building projects, failing the lux / daylight criteria delays IGBC / GRIHA / LEED certification. A periodic NABL-accredited illumination survey is the simplest way to evidence compliance to inspectors and certification bodies.
Are Auriga illumination reports accepted by factory inspectors and certification bodies?
Yes. Because the survey is performed under the Bahadurgarh lab's NABL TC-7710 site-testing accreditation for illumination, the reports are accepted by State factory inspectorates for Factories Act compliance, by building authorities for occupancy certification against NBC 2016, and by green-building assessors (IGBC, GRIHA, LEED) during commissioning and recertification. Reports include lux contour maps, uniformity analysis, the IS 3646 comparison, and the accreditation reference, formatted for direct submission.
