Viparspectra XS4000 LED Grow Light

The ViparSpectra XS4000 is an affordable 480 watt LED grow light that delivers up to 70% higher output than other traditional LED grow lights on the market. The XS4000 features high-quality Samsung LM301B diodes to provide wallet-saving efficiency while generating more usable light per watt.

Efficiency and Yields: The XS4000 LED grow light utilizes high-quality Samsung LM301B diodes that offer high energy efficiency with 2.9 umol/J while generating more usable light per watt and better light canopy penetration.

Optimal Spectrum and Dimming: The XS2000's 3000k warm white, 5000k white, 660nm deep red, and 730nm IR light give your plants the full spectrum light they desire. The red and IR light are especially useful during the flowering stage, which can speed up bloom time and increase yields so you get the best harvest you can. The added dimmer knob lets the grower adjust the light intensity to accommodate plants in all stages of growth - from veg to flower.

Noiseless Operation: No fans means no noise and large, solid aluminum heat sinks help you to achieve the ideal cooling scenario for your system. High performance MeanWell drivers achieve higher par output and longer lifespan to speed up your plant's grow processes and boost yields while saving big on your electric bill.

Viparspectra's XS4000 produces 70% higher output than other traditional grow lights available on the market. The fixture is water-resistant as it has a silicone sealant coating and uses only 480 watts of real power to achieve up to 94% efficiency.
