Superior Heat Dissipation PHOTOBIO T Uses Advanced Cooling Tech to Keep LEDs Running Stronger for Longer

Get to Know the PHOTOBIO T 330 Watt S4 Full Spectrum LED Light

The PHOTOBIO T is a high-performance LED top light engineered for greenhouses and indoor grow operations. Its ultra-slim, linear design minimizes sun interference in greenhouses while providing better canopy access indoors. With 858 µmol/s photon flux and 2.6 µmol/J efficiency, this fixture maximizes light distribution while keeping energy costs low. The closed-loop heat pipe cooling system ensures superior heat dissipation, extending diode longevity and maintaining consistent performance.

Is the PHOTOBIO T Energy-Efficient?

Yes. With 2.6 µmol/J efficacy, the PHOTOBIO T outperforms traditional HPS lighting (1.3–2.1 µmol/J) while cutting operational costs. Its optional AC Power Distribution Tree allows multiple fixtures to run on a single power drop, further reducing infrastructure expenses for large-scale operations.

Features

  • 858 umol/s Photon Flux @ 277V
  • 2.6 µmol/J Efficacy @ 277V
  • Ideal for sole source indoor and supplemental greenhouse applications
  • Thin linear top light design minimizes sun interference in greenhouses while providing better canopy access when applied indoors
  • Highly effective heat pipe cooling system provides superior heat dissipation

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
