Life cycle – Maintenance-freeELECTRO-TECHNOLOGY FOR INDUSTRYTechnologyLife cycleThe life cycle of Pfannenberg signaling devices is defi ned as follows:Xenon flashing lightsWhen the light emission from the fl ash tube has decreased by 30 % aftera certain number of fl ashes. The tube is still not defective, but has becomedarker (can only be measured with electronic measuring instruments). Onaccount of the special Pfannenberg capacitors and fl ash tubes, as well asmany years of experience in fl ashing light technology, Pfannenberg lightshave a very long life cycle (light emission still 70 % after up to 12 millionfl ashes).LED lightsLEDs have a very long life cycle of more than 50,000 hours. Like fl ashtubes, LEDs are not defective after reaching the end of their service life,but rather the light output is reduced by a certain proportion. Thanks tothe careful dimensioning of the LED lights, taking into account all environmentalinfl uences, Pfannenberg lights attain a much longer life cycle.Maintenance-freeWe guarantee a very long, completely maintenance-free service life forsounders. This is due to the fact that no mechanically wearing parts areused.17
