There are several methods to assess the efficiency of a street lamp. Probably the most evidence give two of them:
- Comparative power in kW per 1 km street, assessed by fulfillment of pre-defined standard requirements (preferably EN Standards). This parameter gives evidence about operating cost of a lighting system
- Number of poles per 1 km street, assessed as above. This parameter gives evidence about capital cost of a system
There are two Benchmarking Tables following, referring to both assessment methods described above. Several optics from our portfolio is compared to products of anonymized renowned competitors for 2 Lighting Classes according EN 13201 Standard – CE4 and ME4b.
Statements to Terris design, resulting from Benchmarking Tables above:
- Terris DA Series HE Lamps have unique lamp efficacy, among the best lamps available on the market
- Terris DA Series HE Lamps match competitor´s products also in parameter of maximum pole distance. Only “old-fashioned” HPS (High Pressure Sodium) products could reach bigger pole distance, but at substantially lower efficacy – the Comparative Power is almost twice the Terris DA Series figures

Terris CityLED DA Series Street Lamps are currently available in 4 basic optic grades:
In each optic grade, fine tuning of optometrics is possible in order to adapt the lamp to the customers requirements. The two last digits in optics designation (marked xx above) define the tuning variety.
