Spider Farmer SE4500 320W Full Spectrum LED Grow Light

The Spider Farmer SE4500 320W Full Spectrum LED Grow Light is a high-efficiency bar-style fixture engineered for growers using 2' × 4' grow tents who want professional light distribution, smart automation, and outstanding energy efficiency in a compact footprint.

Updated for 2026, the SE4500 now features Spider Farmer's advanced Bridgelux high-efficiency LED platform. While the diode supplier has changed, the fixture maintains the same proven light output, efficiency, and canopy uniformity that made the SE Series one of the industry's most trusted lighting systems.

Operating at just 320 watts, the SE4500 produces 913 µmol/s of PPF with an impressive fixture efficacy of 2.85 µmol/J. Its three-bar layout distributes light evenly across rectangular grow spaces, minimizing hotspots while improving edge-to-edge canopy development throughout every stage of growth.

The optimized full spectrum combines deep red 660–665nm wavelengths with balanced white light (2800–3000K and 4800–5000K), delivering a spectrum designed to support vigorous vegetative growth, explosive flowering, and consistent harvest quality.

Integrated Bluetooth and WiFi connectivity allows complete control through the Spider Farmer App. Growers can remotely adjust brightness, build custom schedules, automate sunrise and sunset transitions, and synchronize up to 50 fixtures for effortless lighting management.

Its open aluminum bar design provides excellent passive cooling without fans, allowing silent operation while reducing heat buildup inside the grow tent. The detachable driver can also be mounted outside the growing space to further lower canopy temperatures and improve long-term reliability.
