The 2026 Spider Farmer SF4000 has been upgraded with premium Bridgelux high-efficiency LEDs while maintaining the same light output, uniformity, and reliable performance as the previous version.

Designed for serious home growers and professional cultivation, the SF4000 delivers powerful full-spectrum lighting with excellent canopy penetration, high efficiency, and consistent coverage throughout the grow cycle.

Its upgraded diode layout increases the number of LEDs, allowing each diode to operate under a lower load for improved thermal stability, reduced stress, and a longer operating life.

Key Features

• 2026 model upgraded with premium Bridgelux high-efficiency LEDs
• PPE: 2.7 µmol/J
• Excellent canopy penetration with even light distribution
• High diode count for improved efficiency and thermal performance
• Dimmable output with integrated brightness control
• Supports multi-light connection with unified dimming

Full Spectrum Lighting

The SF4000 provides a full spectrum designed to support plants from seedling through to harvest.

• 3000K warm white LEDs
• 5000K cool white LEDs
• 660nm deep red LEDs
• 760nm infrared LEDs

The 3000K LEDs provide additional red wavelengths, while the 5000K LEDs increase blue light for vegetative growth. The 660nm deep red and 760nm infrared LEDs are particularly beneficial during flowering, helping to support bloom development.
