How 200lm/W LED Fixtures Help You Save More Than You Think

In industrial lighting, the biggest challenge for facility managers and procurement teams isn’t just ensuring brightness — it’s doing it with the lowest long-term cost. And the secret often lies in one number: luminous efficacy, or lumens per watt (lm/W).

What Is Luminous Efficacy?

Luminous efficacy tells you how efficiently a light converts power into visible light.

Let’s compare two typical fixture types:

Type	Efficacy	Power	Output
Standard LED	120 lm/W	100W	12,000 lumens
High-Efficacy LED	200 lm/W	60W	12,000 lumens

Result: Same brightness, 40% less power consumption

Annual Energy Cost (per 100 lighting zones)

Type	Power/Zone	Annual Usage
Standard LED	2 × 50W = 100W	360kWh/year
High-Efficacy LED	1 × 60W = 60W	216kWh/year
Energy Cost (%)	100% (baseline)	60% (↓40%)

Energy saved: 40% per year
Each fixture saves 40W, resulting in substantial long-term energy savings.

Less Heat, Less Maintenance, Less Cooling Load

Higher luminous efficacy means less wasted energy as heat.
Fixtures run cooler, reducing failure rates and extending lifespan.

In temperature-sensitive environments like cleanrooms or offices, less heat also means lower HVAC loads — translating into additional operational savings.

---

Fewer Fixtures, Same Illumination

Thanks to professional optical designs (reflectors, secondary lenses), high-efficacy LEDs deliver higher useful light output — one fixture can often replace two old ones.

This reduces:

• Equipment investment

• Installation costs

• Space and structural constraints

Case Study: Food Processing Plant

A factory using 120lm/W fixtures had an annual energy cost of ¥180,000.
After switching to 200lm/W tri-proof lights:

• Total power usage dropped by 40%

• ROI achieved in just 1.5 years, with continuous savings for the rest of the service life

Summary

Indicator	Standard LED	High-Efficacy LED
Luminous Efficacy	120 lm/W	200 lm/W
Power Consumption	High	Low
Heat Output	More	Less
Energy Cost	High	↓40%
Maintenance	Frequent	Stable

The Real Value of 200lm/W:

It’s not just about energy savings — it’s about reducing visible costs and unlocking invisible long-term value for your business.
