Maximize greenhouse and indoor growth with high-efficiency slim top light featuring advanced heat dissipation.

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.
