The Spider Farmer SF4000 LED Grow Light has been upgraded with advanced Bridgelux 3030 high-efficiency LEDs, delivering the same trusted output, uniformity, and performance growers expect, while enhancing durability and thermal stability. Designed for serious indoor cultivators, this 450W full-spectrum LED is ideal for 4x4 ft grow tents and compatible with 6-inch ventilation systems.

With an impressive PPF of up to 1171 umol/s and 2.7 umol/J efficiency, the SF4000 delivers strong canopy penetration and even PPFD distribution across the entire grow area. The upgraded diode arrangement increases uniformity while reducing LED stress by operating each diode under lower load, extending lifespan and improving overall system reliability.

The full-spectrum configuration includes 3000K, 5000K, 660nm red, and 730nm IR, supporting all plant growth stages from vegetative development to flowering. The additional red and IR wavelengths enhance bloom development, accelerate flowering time, and help maximise yield potential.

Featuring a dimming knob with 0-10V control capability, the SF4000 allows flexible intensity adjustment and supports multi-light connection with unified dimming, making it suitable for both home growers and commercial cultivation.

Built with thick aluminium heat sinks, a high-safety performance driver, and waterproof cable protection, the SF4000 operates quietly with no fan noise while maintaining excellent thermal management.

Whether used in a 120 x 120 cm grow tent or a larger setup, the Spider Farmer SF4000 offers professional-grade lighting performance backed by a 5 year warranty.
