Efficiency and cost effectiveness

Every one of our lighting concepts delivers measurable efficiency. They improve energy efficiency, reduce TCO and deliver a fast return on investment. We don’t just focus on developing lighting concepts that deliver maximum effect with as few luminaires as possible, but also on the use of very efficient lighting technology that we developed ourselves. Our patented reflector technology with 3D facets ensures that up to 20% more light lands on your products.

IEC62722-2-1 is regarded as an international standard for specifying the efficiency of an LED luminaire. Under standard conditions our own light laboratory determines the efficiency of the luminaires. All resulting measuring data are recognised by VDE. This means that we always give you realistic values that provide clear information on the cost effectiveness and the power consumption of the product. A close comparison of the measurement methods is worthwhile.

 

Measurement situation under standard conditions

Measurement of the system luminous flux and the electric system power of the luminaire in a thermally saturated condition (operating temperature of the LEDs of 80 °C, for example).

Measurement in a specified ambient temperature of 25 °C.

Measurement of the system luminous flux and the light distribution curve including all optical components (reflector, lenses or filters)

* The system luminous flux is the amount of light emitted by the luminaire in operation.

Ansorg's Comparison of efficiency

  • 3100 lm/25,5 W, 121 lm/W
  • Supposed efficiency increases compared with the measuring situation under standard conditions: 13,1%

 

  • 3681 lm/25,5 W, 144 lm/W
  • Supposed efficiency increases compared with the measuring situation under standard conditions: 34,6%

 

  • 4094 lm/26,2 W, 156 lm/W
  • Supposed efficiency increases compared with the measuring situation under standard conditions: 45,8%

 

Our example shows that luminaires only save operating and energy costs when the test situation does not differ from the real conditions. The luminaire Coray CMT 830 MFL has an efficiency value of 107 lm/W.
