The ViparSpectra K5000 is a premium bar-style LED grow light designed to deliver powerful, uniform illumination over a 4’x4’ canopy, outperforming many other lights in its class. It employs high-quality Samsung LM301H and Osram 660 nm diodes - 1260 in total - biasing denser diode placement at the edges to ensure even coverage across the canopy. With a real-world usable light output of approximately 1200–1273 µmol/s PPF and a usable efficiency of 2.4–2.6 µmol/J, it rivals the output of a 1000 W HPS system while only drawing around 500 W. At a hanging height of 16″, the KS5000 achieves peak PPFD near 1000 µmol/m²/s, dipping to about 618 µmol/m²/s at the canopy edges, yielding a decent uniformity ratio of 1.62.
