How to Choose Industrial Lighting

Good quality lighting is essential for every manufacturing facility—both at night and during the day where natural light is insufficient. Proper lighting improves productivity, reduces errors, enhances safety, and creates a better working environment.

1. Lux Level (Illuminance) – The Most Critical Factor

Lux defines how much light reaches the working surface.

Recommended Lux Levels:

• Manufacturing / Assembly Areas: ≥ 500 lux
• Godowns / Warehouses: ≥ 250 lux
• Corridors / General Areas: 150–250 lux

A well-lit facility:

• Reduces worker fatigue
• Improves accuracy
• Enhances morale
• Makes the factory look professional and efficient

👉 It is always advisable to share:

• Factory layout
• Mounting height
• Required lux levels

with a lighting company. They typically provide lighting simulation (Dialux) showing:

• Fixture positions
• Mounting heights
• Achieved lux levels
• Uniformity

2. Light Uniformity (Often Ignored, Very Important)

Uniformity ensures there are no dark patches or harsh bright spots.

• Poor uniformity causes eye strain and errors
• Good design ensures shadow-free, evenly distributed light

3. Colour Rendering Index (CRI)

CRI measures how accurately colors appear under light.

• CRI 80 → Suitable for most industries
• CRI 90+ / 97 → Required for:
• Printing
• Textile inspection
• Paint & color-sensitive work

👉 Higher CRI = better color accuracy, but slightly lower efficiency and higher cost.

4. Colour Temperature (CCT)

This defines the color tone of light.

Recommended:

• 5000K – 5700K → Ideal for factories
• Natural white
• Comfortable for long working hours

Avoid:

• 6500K (Cool white/bluish)
• Causes eye fatigue over time
• Harsh for industrial environments

5. Fixture Quality – The Real Differentiator

After lux, CRI, and CCT, the fixture quality determines performance and lifespan.

5.1 Thermal Management (Most Critical for Longevity)

LEDs generate heat from the back side. Poor heat dissipation leads to:

• Faster lumen depreciation
• Color shift
• Shorter life

Best Practice:

• Use extruded aluminum heat sinks
• Avoid cheap die-cast aluminum

👉 Key fact:
Every 10°C reduction in LED temperature can double lifespan

5.2 LED Chip Quality & Quantity

• Use LEDs with ≥ 150–200 lumens per watt (chip level)
• Prefer over-designed fixtures:
• Example: 200W light using LEDs rated for 300–400W
• Leads to lower stress & longer life

5.3 LED Driver Quality

The driver converts AC to DC.

What to check:

• Efficiency ≥ 90%
• Good thermal design (metal housing)
• Surge protection (≥ 10kV)
• Warranty ≥ 3–5 years

👉 Poor drivers are the #1 failure point in LED lights.

6. Installation Best Practices

6.1 Mounting

• Always install lights vertically downward
• Proper spacing avoids shadows

6.2 Electrical Wiring

• Separate lighting circuits from heavy machinery
• Prevents voltage spikes damage

6.3 Cable Design

• Use proper cable sizing
• Industrial lighting is a significant load

7. Maintenance & Lifecycle Consideration

This is where many buyers make costly mistakes.

• Installation cost (using lifts) can be 20–25% of fixture cost
• Replacement is equally expensive and disruptive

👉 Therefore:

• Choose high-reliability fixtures
• Check real-life installations
• Ensure post-warranty serviceability

8. Warranty & Serviceability

• LED chips: 5–7 years
• Drivers: 3–5 years
• Confirm:
• Availability of spare drivers
• Replaceable LED modules
• On-site service support

Final Advice (Most Important Insight)

Don’t buy industrial lighting based only on:

• Wattage
• Price

Instead, evaluate:

✔ Lux delivered on floor
✔ Uniformity
✔ Thermal design
✔ Driver quality
✔ Serviceability

In One Line:

A good industrial lighting system is not about how bright the fixture is, but how effectively and reliably it delivers usable light on the workspace over time.
