The Spider Farmer SF-4000 LED Grow Light is a powerful full spectrum LED grow light engineered for growers who want maximum yields, high efficiency, and professional-level performance in indoor cultivation environments.

Powered by premium Samsung LM301H EVO diodes, the SF-4000 delivers intense, evenly distributed light across the canopy while maintaining exceptional energy efficiency. Its full spectrum output supports every stage of plant growth, from seedlings and vegetative development through to heavy flowering and fruiting.

With a powerful output of approximately 450W, the SF-4000 provides excellent canopy penetration and strong PPFD levels, making it ideal for larger grow tents and high-yield cultivation setups. The dimmable design allows growers to adjust light intensity depending on plant stage and environmental conditions.

Built with a fanless passive cooling system and detachable driver, the SF-4000 runs quietly while helping reduce grow room heat, creating a more stable growing environment.
