The Phlizon PH-B8-D 640W Full-Spectrum Dimmable LED Grow Light delivers powerful output in a manageable size. Highly efficient, it’s equipped with Samsung LM301B diodes and a balanced full-spectrum layout — with added red and IR light to encourage denser flowering and enhanced resin production. Its bar design ensures even light distribution over a 5x5ft veg area and 4x4ft during flower. The dimmable driver offers smooth control over PPFD levels, meaning you can fine-tune intensity for different growth stages and plant types. Featuring passive cooling through a robust aluminum heat sink, it runs quietly and reliably — and it’s backed by Phlizon’s 3-year warranty. For a simpler model with similar coverage that doesn’t have dimming capability, the PH-B8 delivers exceptional full-spectrum illumination at a lower cost. For smaller grows, the 600W LED is a perfect entry point with on-point performance.
