Spider Farmer SE4500 320W LED Grow Light – 2x4ft Coverage, App Control, Full Spectrum

Meet the Spider Farmer SE4500, a 320W LED grow light crafted for serious indoor cultivation. Built with Bridgelux premium diodes, it delivers an impressive efficacy of 3.14 μmol/J and a steady 913 μmol/s photon output. The extended 3-bar design creates uniform, edge-to-edge illumination across a 2×4 ft canopy, supporting cycles from seedling through harvest with reliable consistency.

Performance you can feel in your growing space

• Efficient, high-precision light: Bridgelux diodes power a rich spectrum for robust plant responses.
• Uniform canopy coverage: A three-bar layout minimizes hot spots and ensures consistent intensity across the grow area.
• 2×4 ft target area: Ideal for compact tents and dedicated grow corners, helping you optimize space and yields.

Smart control and flexible grow planning

The SE4500 pairs powerful hardware with thoughtful software features. Use the Spider Farmer App to tailor light schedules, simulate natural day cycles, and adjust brightness remotely while you’re at home or away.

• Custom light schedules: Create day/night patterns that fit your plant stages.
• Sunrise/sunset simulation: Gentle transitions can reduce plant stress and simplify routine care.
• Remote brightness adjustments: Fine-tune output from anywhere to match plant needs and tent conditions.

Spectrum designed for plant-centric growth

The SE4500 uses a tuned full spectrum to support ongoing development: a plant-focused 437 nm blue component plus 50–55% deep red at 660–665 nm, paired with white light in the 2800–3000K and 4800–5000K ranges. This combination helps fuel healthy development from seedling to harvest while giving you flexibility in real-world setups.

Ease of use, scalability, and after-sales support

The fixture features a digital display for clear brightness readouts and easy adjustments. It also supports daisy chaining—up to 50 SE4500 units can be linked to a single master light for larger installs. Backed by a 5-year warranty, responsive service, and repair centers in the USA/Canada/UK/Germany, you can grow with confidence.

• Digital dimming with a clear display for precise settings.
• Daisy chain up to 50 units for scalable commercial or multi-tent setups.
• 5-year coverage with access to local repair centers for peace of mind.

Whether you’re cultivating a few thriving plants at home or managing a small commercial grow, the SE4500 offers a balanced mix of high efficiency, practical control, and reliable performance. It’s designed to support your lighting strategy without locking you into a single method, leaving room for growth and experimentation.
