Illumination & Lux Level Testing India | NABL Accredited

Auriga Research provides NABL-accredited illumination and lux level testing services for factories, offices, hospitals, warehouses, and commercial buildings across India. Our measurements use calibrated digital lux meters to verify compliance with IS 3646, NBC 2016, Factories Act requirements, and green building certification standards.

Proper illumination is a critical workplace safety parameter. Inadequate lighting contributes to accidents, eye strain, and reduced productivity. Our surveys measure average illuminance, uniformity ratios, and daylight factors — delivering reports that satisfy regulatory inspectors and certification bodies.

Illumination Testing Scope

Workplace lux level measurement per IS 3646 (Part 1)
Average illuminance and uniformity ratio calculations
Daylight factor assessment for green building certification
Emergency lighting verification
Outdoor area illumination — parking, pathways, perimeter
Glare assessment and luminance measurements
Post-retrofit lighting performance verification

Who Needs Illumination Testing

Factories complying with Factories Act workplace safety norms
Green building projects pursuing IGBC, GRIHA, or LEED certification
Hospitals and laboratories with specific illumination requirements
Facility managers validating lighting retrofit performance
Architects and MEP consultants during building commissioning

Turnaround Time

On-site illumination surveys for a single facility take 1-2 days. Reports with lux contour maps, uniformity analysis, and compliance assessment are delivered within 5-7 business days of field measurement.

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. Green building certifications and NBC 2016 also specify minimum daylight and artificial lighting requirements.

Where is illumination testing typically conducted?

Illumination testing is conducted in factory production floors, warehouses, offices, hospitals, laboratories, 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.

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, LEED) require lux measurements during commissioning and recertification. It is advisable to retest after lighting retrofit projects, after significant layout changes, or when occupants report visual discomfort.
