We replaced the 36 existing 400-W reflectors with 32 180-W H LUM lamps with wide optics 010, cutting the system’s input power to a third.
We upgraded the lighting with the DALI smart management system, which supports automatic adjustments of illumination levels based on requirements. The system, designed in collaboration with IKU, supports pre-setting illumination levels on individual buttons (300 lx for PE, 500 lx for matches and 750+ lx for televised matches), and remote management through a mobile app. The app can be used to manage every light individually, or to manage lighting in each of the thirds separately.
The light switch panel makes it possible to switch lights on and off and control the illumination by thirds of the hall, as well as to change the lighting levels between 300 lx, 500 lx or the highest level. Motion sensors ensure that the lights automatically switch off after 30 minutes, if nobody is in the hall. If a sensor detects motion, the lights switch back on to the last used setting.
Most of the time the gym is used for PE, so the basic lighting setting is fixed to 300 lx across the whole hall, and locked for security.
Even though the system’s input power has decreased to a third, the illumination of the hall has increased by 60%. The smart management system brings even more power savings, so the investor will recover the cost of the investment in less than 4 years. The new lighting improved the visibility, as well as the appearance of the hall, providing users with better conditions for their activities, and improving their wellbeing.
One of the main reasons why the client selected our solution is zero maintenance costs during the 5-year warranty period, with the estimated lifespan of the lights at 60,000 hours.
We have used the H LUM LED lights in several similar projects in the past: in Podbočje, Vodice and Radeče, as well as in 5 halls in Karlovac.
