What is retrofitting?Make the existing fixture durable/more energy efficient!
Historical DecorativeStreet lighting
Why retrofitting existing fixtures? Most luminaires are often still in good condition, but the inefficient light source does not meet the requirements.
Important issues with currently installed light sources:- Energy inefficient- EU regulation (2015) white light instead of yellow light- High maintenance costs through lamp replacements
Why choose QL induction as retrofit solution?
Advantages QL induction lighting:- Made in Holland!- Reduce energy costs up to 50%- ROI between 2-4 years realistic- Field proven lifetime (100,000hrs and virtually no
maintenance)- High Color rendering index (RA > 80)- Dimmable to 50% - Trend to white light (QL available in 4000K and
5000K)
Trend to white lightReplacement of yellow light sources to white light is a trend that is already going on for many years. Studies have shown that the human eye is more sensitive to white light at night.
QL has a high SP ratio of 1.6The S/P ratio indicates how many times more the QL lamp generatesvisual effective light to the human eye at night (compared to the eyesensitivity during daytime).

Why choose QL induction and not LED?
Economics:Return on investment fromQL induction is only half of LED.
Technology and life:LED is an emerging technology. QL Induction is a proven technology and 100.000 hours life is proven since 1991.
