Purchase of LED streetlights – Part 2

The contracting authority intends to carry out a modernization of public lighting in the Budapest area with innovative, integrated LED light sources, suitable for luminous flux control via DALI protocol, based on a framework agreement. The framework quantity for the second part is: 1700 units. The contracting authority commits to ordering 70% of the framework quantity. Types and lengths of connecting cables: Types: - NYY-J (3 x 2.5 mm2) - MBCU (3 x 1.5 mm2) Typical cable length: 4 m for NYY-J (3 x 2.5 mm2) 10 m for MBCu (3x1.5 mm2) Maximum cable length: 10 m for NYY-J (3 x 2.5 mm2) 20 m for MBCu (3x1.5 mm2) • Mounting method: on Ø42-60 mm pole arm General technical requirements for luminaires: - The offered luminaires must have ESD protection system from the manufacturer, based on standard EN 61340-5-1. - The offered luminaires must comply with the requirements of Regulation (EU) No 1194/2012 on ecodesign requirements for directional lamps, light sources and control gears. - The specified value for LED L90B50 lifetime: min. 80,000 hours - The stabilized total luminous flux value must not be less than 95% of the initial total luminous flux value up to a nominal power of 150 W, and 90% of the initial total luminous flux for powers of 150 W or more. - Specified requirements for the colorimetric data of the luminaire: o 2850 K ≤ CCT (LM-79) ≤ 3150 K o CRI (Ra) ≥ 70 o -0.0050 ≤ Δuv ≤ +0.0050 - Electrical parameters: the luminaire's operability in the voltage range of 210 V-250 V – at a constant AC voltage of 50 Hz. Power factor and total harmonic distortion for luminaires with a nominal power of more than 25 W (in the 210 – 250 V supply voltage range): PF ≥ 0.90; THDi ≤ 20% Power factor and total harmonic distortion for luminaires with a nominal power of 25 W or less (in the 210 – 250 V supply voltage range): PF ≥ 0.80; THDi ≤ 30% The harmonic values of the absorbed current must comply with the requirements of standard MSZ EN 61000-3-2. The harmonic values of the absorbed current must comply with the requirements of standard MSZ EN 61000-3-2. The total luminous flux values measured in the 210 V – 250 V voltage range must fall within ±1% of the steady-state total luminous flux measured at nominal voltage. - Compliance with the EMC standard for wireless interference (MSZ EN 55015). - Protection and impact resistance: the offered luminaires must comply with the protection rating according to standard EN 60529. The offered luminaires must comply with the impact resistance according to standard EN 62262. Light source: • The contracting authority emphasizes that only High Power LEDs are accepted. The contracting authority considers LEDs with a power of more than 0.75 W per LED and a driving current exceeding 150 mA as High Power LEDs. • The contracting authority does not accept the use of so-called "retrofit" light sources (interchangeable with non-LED light sources, replaceable individually in a socket). • The light source is an integral part of the entire luminaire structure, so the warranty requirements also apply to the light source. Photometric parameters • The luminous efficacy of the offered luminaires must not be less than 130 lm/W. Surge protection: • The luminaire's surge protection – using a separately replaceable component – must be designed to protect downstream components from both network disturbances and secondary effects of lightning strikes. Minimum requirements for surge protection against atmospheric or switching surges for the luminaire: Impulse voltage withstand: min. 10 kV; 1.2/50 µs Impulse current withstand: min. 5 kA; 8/20 µs Impact resistance: • The minimum impact resistance value is IK 08. Sealing of optical and gear compartments: • The protection rating of both the optical and gear compartments must be at least IP 66. The expected minimum warranty period is 14 years. During the execution, the offered and supplied luminaires...
