Whether it's a cleanroom, laboratory, manufacturing unit, or inspection area, the correct illumination ensures optimal visibility, reduces errors, and supports regulatory compliance.

What is Light Intensity?

Light intensity is the measure of how much light (illuminance) reaches a surface, usually expressed in lux (lx). It plays a key role in ensuring proper working conditions and product inspection accuracy.

Why is Measuring Light Intensity Important?

• Ensures visual comfort and precision for operators

• Supports GMP, ISO, and OSHA lighting standards

• Aids in quality control and defect detection

• Helps maintain consistent working conditions

• Reduces strain and errors in visually intensive tasks

Where Light Intensity is Measured:

Cleanrooms – To meet GMP/ISO Class lighting levels

Pharmaceutical Labs – For accurate sample handling

Manufacturing Lines – Ensures visibility during production

Inspection Areas – To detect product defects or inconsistencies

Healthcare Facilities – For patient safety and diagnostics

Warehouses – Enhances safety and efficient operations

Equipment Used: Lux Meter / Light Meter – A device used to measure the brightness (illuminance) of light falling on a surface, expressed in lux (lx).

Calibrated Sensors – For high-accuracy and traceable measurements

Data Loggers – For long-term monitoring of light conditions (if needed)

Recommended Light Levels (As per ISO/GMP Guidelines):

• Cleanroom ISO Class 5–7: Typically ≥ 500–750 lux

• General Work Areas: 300–500 lux

(Note: Exact values may vary depending on regulatory body or application.)

How the Test is Performed:

1️⃣ The lux meter is positioned at various locations within the room or work area to accurately assess light levels across the space.

2️⃣ Readings are recorded under normal operating conditions

3️⃣ Results are compared with relevant regulatory or client-specific standards

4️⃣ Recommendations are made if any areas fall below required levels

Ensure Compliance & Comfort with Light Audits

Routine light intensity audits are essential to maintain consistency, reduce operator fatigue, and ensure compliance with workplace and regulatory lighting standards.
