The Electric Sky 180 V2 (ES180 V2) is a compact 180-watt grow light that flowers up to a 2'x4′ area. It features a wideband spectrum with a color ratio tuned for rapid vegetative growth and heavy flower yield. Light is projected in two directions from the linear lenses to form a rectangle. The distributed design allows for maximum headroom. Version 2 builds upon the original Electric Sky 180's success, with greater brightness for intense light output in the smallest grow spaces.
