The ViparSpectra XS4000 is a growing lighting fixture with an actual power draw of 450W. It’s designed to provide full-spectrum illumination for indoor plant cultivation. The unit incorporates Samsung LM301B LED diodes. This system works well for vegetative stages with a coverage area of 5x4 ft at 28’ and a flowering coverage of 5x3 at 24’. Light intensity can be adjusted from 0% to 100% via an integrated dimmer control. For thermal management, the XS4000 utilizes large aluminum heatsinks, enabling a fanless design that results in silent operation. The cooling system contributes to a rated lifespan exceeding 100,000 hours. A daisy chain function is included, allowing for the connection of multiple units for further optimization of the grow space.
