The SolarSystem-series is a highly intelligent LED cultivation system by California Lightworks. This series can be entirely programmed using the SolarSystem Controller (which can be ordered separately). The SolarSystem grow lights are developed and manufactured in California Lightworks’ factory in Canoga Park, California. The LEDs in the SolarSystem 275 grow lights are made by Osram and are the most powerful LEDs on the market. The lights are watertight and, therefore, they are not damaged by splashing water or in humid environments. The fans have a lifecycle of 50,000 hours and can easily be replaced. The LEDs themselves have a minimum of 50,000 burning hours. California Lightworks gives a 5-year manufacturer warranty on the SolarSystem cultivation lights.
