Germany – Lighting equipment and electric lamps – Construction and delivery of LED retrofit kits

Opportunity description

The Bundeskunsthalle plans to convert the general lighting in the Great Hall and the atrium hall on the ground floor and upper floor to LED lamps. The services are being tendered in 2 lots. Lot 1 - Construction and delivery of LED retrofit kits Lot 2 - Delivery and programming of the control systems Retrofit kit for replacing the existing lamps and ballasts LED replacement modules for one luminaire The replacement module must be designed in such a way that simple and quick installation is possible. It can be mounted, for example, in the old sockets, in the holder for the UV panes, or magnetically on the luminaire housing. Screw connections should only be made in existing holes. The module must be equipped with tunable-white LEDs between 3000 K or warmer and 5000 K or cooler. The color rendering in all light colors is at least Ra ≥ 90, R9 ≥ 50 The UV component of the total radiation is below 0.1% (highest protection level) The light output of the LED modules must be dimensioned so that the retrofitted luminaire provides a luminaire luminous flux of at least 5000 lm in every light color. The efficiency of the LEDs used should be at least 150 lm/W The color tolerance is ≤ 3 SDCM Service life of the LEDs L90/B10 ≥ 50,000 h, L70/B50 ≥ 100,000 h Luminaire luminous flux in every light color 5000 lm. The retrofit modules are pre-wired so that a simple connection from module to module is made via plug-in or terminal connections. The existing recessed luminaires of the Bundeskunsthalle for basic lighting will be converted to LED. The existing control lines of the 1-10V control system (2 per luminaire) will be used to control the ballasts. The ceiling will not be opened. The luminaires will be equipped with tunable-white LEDs and suitable ballasts (DALI DT8). A Casambi Bluetooth control system is planned for simple control of the luminaires. The tender relates to the delivery of the components required for this purpose and their on-site programming. The devices are installed via components. Procedure: open.
