Framework agreement for the supply of LED luminaires 2023-2026, optional 2027

LED street and pedestrian crossing lights

The city of Essen intends to replace or rebuild around 2,000 outdated street lights with modern LED lights or to install new ones over a period of three years per year. For all Essen streets and pedestrian crossings (HVDC), LED luminaires with corresponding luminous fluxes for standard-compliant illumination are to be supplied, taking into account nature conservation conditions for insect friendliness. For a future-proof installation as part of Smart City, the luminaires must be equipped with a three-stage switch and up to two Zhaga bases. Particular attention is drawn to the realization of the power reduction during the night.

LED wall and ceiling lights

The city of Essen intends to replace or build around 150 LED ceiling lights or LED wall lights in underpasses over a period of three years per year. The LED luminaires are to be supplied with appropriate luminous fluxes for standard-compliant illumination, taking into account nature conservation conditions for insect friendliness. All components of the luminaires that are relevant for testing and maintenance must be accessible from below without dismantling them from the wall or ceiling. The LED luminaires are to be equipped with a three-stage changeover switch, which makes it possible to set different luminous flux gradations by simple operation without having to make any further intervention in the driver programming.

The contract will be awarded to the most economical tender. Energy consumption over 10 years is also taken into account. This means the acquisition costs per luminaire type (EP unit price) plus the cost of energy (energy consumption costs) per luminaire type over a period of 10 years.

The quantities listed in the bill of quantities have been roughly determined on the basis of empirical values and refer to the planned period of three years. They can be exceeded or undercut. No claims can be asserted if not all quantities used are accepted. At the same time, it is defined that the difference between the estimated quantity and the quantity of materials called up for each item in the specified period shall not exceed 100 %.
