The Maxsisun PB4000 Pro is a commercial-grade LED grow light crafted for full-cycle indoor gardening, especially well-suited to 4 x 4 ft flowering areas or slightly larger vegetative spaces. It delivers a full-spectrum output to support every stage of plant growth from seedling to harvest. Equipped with 1,400 high-performance Samsung diodes and powered by a Mean Well XLG‑240‑H‑AB driver, the PB4000 Pro pulls a true 400 W from the wall, while offering an efficient photon efficacy that rivals 800 W HID systems with significantly lower heat output and energy consumption. A thoughtful addition is the included remote control, which allows for dimming anywhere from 0–100% and supports grouping multiple lights together for synchronized settings. Maxsisun 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 MU1200 or PB1000 Pro systems.
