If the driver is connected to the power first, electrical power is output at the secondary side, which leads to overvoltage and therefore damage to the lights if they are connected. Can LOOX lights be used in vehicles, for example? Yes, but an upstream voltage stabiliser must always be installed, since voltage fluctuations occur in on-board power supplies and voltage peaks (even slight overvoltage) can reduce the service life of the lights considerably or cause damage. Why does the light flash at regular intervals when it is switched off? This is caused by leakage current in the electrical installation which is charging the capacitor in the driver until it briefly gives off the power at regular intervals to discharge itself and the light therefore briefly flashes. Solution: Check the entire installation. Why is the door sensor switch not operating correctly? When sliding doors are being used, the door sensor switch cannot record the rapid movement and the movement of the door properly. Dark surfaces (e.g. jet black) have poor reflection. The optical sensor may therefore fail to detect the door panel. Solution: Use motion detectors Why does my LED light flash? Flashing is a sign of under or overloading. Use a driver with higher power or reduce the number of lights. What may be the cause if an RGB LED flexible strip light is only displaying individual colours? The clip connector has been connected the wrong way round or the strip has been connected to the wrong end or to the driver. Troubleshooting How can I compare the output of an LED light with a halogen light? Use the cone of light and compare the values at 500 mm. A 20W halogen light features approx. 600 lx at 500 mm.
