LEDs have a lifetime of 50.000 hours, the equivalent of 8-10 years of daily plant lighting. After this period, LEDs will start to wear out. Instead of having to throw away your light module, PlantSpectrum’s unique circular design allows it to be used eternally. Simply slide in a new LED Board from the side. No soldering is needed, the board comes with a power cable and plug attached. Easy replacement: Use the Torx key that comes with PlantSpectrum to unscrew the thick end cap. Detach the strain relief from the end cap and slide out the LED Board and replace it. Attach the new strain relief and fix the end cap again. Warning: do not power on without using the housing.
