The Optic 4 Gen 3 405 W by Optic LED is a purpose-built flowering-phase COB LED fixture designed for serious indoor cultivators seeking maximum punch in bloom. It packs four high-output CREE XLamp CXB2540 COB chips with either a warm‑white 3000 K or a mixed 3000 K/5000 K configuration tuned for intense flowering performance. These COBs generate over 220 W of core light output, while a surrounding array of 64 supplemental 5 W Bridgelux and Epistar LEDs contribute an additional ~180 W of focused spectrum including deep red, royal blue, UV‑A, and far‑red diodes for enhanced resin production and photosynthesis. Optic LED provides many lighting solutions for growing environments. If you’d prefer to try out something different from them, don’t hesitate to check out their Optic 1 XL Dimmable 3500k COB or Phantom 1XL Dimmable systems.
