Understanding Lux and Lumens: How Aeron Luminaries Ensures Compliance with Both Standards

Visual Representation of Lumens and Lux

When it comes to evaluating lighting quality, two terms often come into play—lux and lumens. While many people use them interchangeably, they are not the same. Both are essential in determining how effective a lighting system will be in real-world applications, whether in industrial plants, commercial spaces, or outdoor installations.

At Aeron Luminaries, we focus on designing lighting solutions that comply with both lumens output (brightness) and lux levels (illuminance) to ensure optimum performance and safety across industries.

What Are Lumens?

Lumens (lm) measure the total amount of visible light emitted by a source.

• The higher the lumens, the brighter the light appears.

• Lumens tell you how much light a fixture produces, but not how that light spreads or where it falls.

For example, a 20,000-lumen floodlight might seem powerful on paper, but if the beam is scattered poorly, the actual illumination on the ground could still be insufficient.

What Is Lux?

Lux (lx) measures how much luminous flux (lumens) falls on a surface area.

• 1 lux = 1 lumen per square meter.

• Lux depends on distance, beam angle, and environment.

For instance:

• A 1,000-lumen bulb placed close to a desk might give 500 lux.

• The same bulb installed higher in a warehouse might give only 50 lux on the floor.

This makes lux a practical measure of usability—it tells us how well a space is lit for a specific activity.

Why Lux and Lumens Are Variable

• Distance from source: The farther the light source, the lower the lux on a surface.

• Beam angle: Narrow beams concentrate lumens into higher lux levels; wide beams spread them thinly.

• Application type: A stadium floodlight requires different lux levels compared to an office light.

This variability means lumens alone cannot guarantee adequate lighting—lux levels must be verified based on site requirements.

Recommended Lux Levels (as per industry guidelines)

• Office workstations – 300–500 lux

• Classrooms – 250–500 lux

• Industrial assembly areas – 500–750 lux

• Warehouse storage – 150–300 lux

• Roadways / Outdoor lighting – 10–50 lux
  

How to Determine Lux Levels

Lux can be measured using a lux meter at different points of the target area. In professional projects, we also use lighting design software (Dialux, Relux, etc.) to simulate layouts before installation.

Steps we follow at Aeron Luminaries:

1. Measure lumens of the LED source using certified photometric reports.

2. Calculate lux distribution through beam angle design and simulation.

3. On-site verification using lux meters after installation.

4. Adjust fixture orientation/quantity to achieve the required lux standard.
   

Aeron Luminaries’ Commitment to Standards

At Aeron Luminaries, we ensure that our products comply with both lumens output standards and lux level requirements:

• All products undergo LM-79 and LM-80 testing in NABL/ILAC accredited labs.

• We design optical lenses and reflectors to maximize lux efficiency, ensuring light is not wasted.

• Our in-house engineers simulate lighting layouts to confirm that clients achieve the required lux standards before installation.

• Regular photometric testing and field audits guarantee consistent performance over time.
  

Final Thoughts

Both lumens and lux are crucial for defining the quality of lighting. Lumens tell us how much light is produced, while lux tells us how well the light is applied. At Aeron Luminaries, we bridge this gap by creating lighting solutions that not only emit sufficient lumens but also deliver the required lux levels for safe, efficient, and reliable illumination.

By maintaining strict compliance with industry standards, we ensure that our customers receive lighting solutions that are not only powerful but also purposeful.
