Since the commercialisation of the fluorescent tube, flicker has been a major cause of discomfort in people, particularly those working under them for long periods, during winter months. Fluorescent lighting has been documented to induce tiredness, fatigue and migraines.
LED technology has reduced flicker from fluorescent typically by a half. This is insufficient to improve crucial human-centric elements. Good quality lighting with low flicker improves mood, motivation and productivity in staff regardless of their surroundings, for example in office or industrial environments, or in leisure and retail centres.
Under-driving the LED (at 10%) and optimising the performance of the driver (96%) results in Waveguides fixtures delivering extremely low flicker of just 3%. The feedback from Waveguide clients of this has proven the impact that such low flicker does have. The images below, taken from a basic mobile phone, show the evidence of flicker from a fluorescent, an LED panel and a Waveguide WaveStar fitting. Whilst we can stare at a fluorescent or LED panel and not witness this by eye, the retina is picking up the flicker and this is indeed the cause of the human-centric impacts.
