HQI lamps / Metal halide lamps (MH)
Why they are still so popular
Metal halide lamps, also known as HQI lamps, have been in use since the mid-1960s. They are still widely used today and belong to the group of high-pressure discharge lamps.
Their continuing high popularity is due in particular to their excellent photometric performance: They offer an extremely high luminous flux of up to 230,000 lm, a very economical luminous efficacy of up to 115 lm/watt, and an excellent colour rendering index (Ra / CRI) of up to 90 compared to other discharge lamps.
All this makes them a perfect alternative to LED lighting for sports facilities that, for example, have shorter switch-on times and do not exceed an annual lighting duration of approx. 400 – 500 hours. Or for clubs that need a high-quality lamp replacement for existing installations, or for whom the high investment costs in an LED floodlight system do not pay off.
Optimal and standard-compliant lighting and illumination of the sports facilities for pure sports use can still be achieved with conventional lighting – effectively and cost-saving!
