Due to their low energy usage, low heat output, good colour rendering, and exceptional luminous efficiency, LED lights have become the main form of artificial lighting in care units today. For our lights, we have selected high-performance LEDs (130–140 lumens/Watt) with colour temperatures (4500 Kelvin or “neutral white”) that are visually comfortable and do not alter tones under their light.
We do not use ordinary LED light bulbs, whose specifications render them inadequate for technical uses such as for surgery or dermatology. The LEDs we use are soldered onto a printed circuit board that is efficiently cooled by a heat sink. Like this a minimum working life of 50,000 hours, or around 25 years of intensive use is achievable.
