Spider Farmer SE-4500 320W Smart LED Grow Light
Maximize your canopy potential with the Spider Farmer SE-4500 320W Smart LED Grow Light. Engineered specifically for rectangular 2'x4' (70x140cm) grow footprints, this professional-grade 3-bar fixture provides exceptional light uniformity without generating the devastating hotspots common in traditional setups. Driven by high-efficacy Bridgelux LEDs alongside premium 660nm Hyper Red diodes, the SE-4500 balances extreme energy savings with an intense full-spectrum output designed to push flowering and fruiting cycles to their absolute limits.
With newly integrated Bluetooth and Wi-Fi smart app controls, you can seamlessly manage your environmental schedules from anywhere.
Key Features
  • Smart App Eco-Control: Built-in Bluetooth & Wi-Fi let you program photoperiod schedules, automate sunrise/sunset dimming, and receive high-temperature alerts on the Spider Farmer App.
  • Uniform 3-Bar Footprint: Optimized multi-bar layout concentrates diodes along the edges to tackle edge drop-off, providing perfectly balanced PPFD across your entire 2x4ft workspace.
  • Advanced Bridgelux Platform: Outfitted with 1,005 high-performance diodes that deliver a blistering PPE of 2.85 μmol/J while pulling just 320 Watts from the wall.
  • Deeper Canopy Penetration: Includes dedicated 660nm deep red wavelengths to mimic late-summer sunlight, driving robust photosynthesis and explosive bud development.
  • Commercial Daisy-Chaining: Features a precise digital display dimmer box that lets you link and control up to 50 fixtures simultaneously.
  • Cool, Silent Operation: The open-bar design and heavy-duty aluminum heat sinks improve passive airflow, dropping tent heat down without the need for loud integrated fans.
Tailored Full Spectrum Output
The SE-4500 abandons generic "purple" spectrums for a highly precise, sun-like layout:
  • Warm White Light (2800K-3000K): Delivers essential red spectrum light to trigger strong bloom cycles and bulk up flower density.
  • Cool White Light (4800K-5000K): Rich in blue wavelengths to accelerate rapid vegetative growth, shorten internodal spacing, and reinforce root bases.
  • Hyper Red Light (660-665nm): Crucial light bands that supercharge plant metabolism during the peak flowering phase for heightened terpene production.

High-Efficiency Lighting for 2x4 Grows

Give your indoor plants powerful, even coverage with the Spider Farmer SE4500 320W LED Grow Light, a bar-style full-spectrum fixture designed around a 70x140cm growing area.

Delivering 913 µmol/s PPF at an efficiency of 2.85 µmol/J, the SE4500 combines strong light output with efficient power consumption. Its three-bar design spreads light more evenly across the canopy, helping reduce hotspots and shadowing while improving light penetration.

Bluetooth and Wi-Fi connectivity allow the SE4500 to work with the Spider Farmer app for smart lighting control, including schedules and sunrise and sunset simulation. Dimming and daisy-chain functionality also make it easy to adapt light intensity as plants progress through their growing cycle.
