800W top light with 2400 µmol/s output, 3.0 µmol/J efficiency, and S5 spectrum. Built for greenhouse and single-level commercial grows.

The PHOTOBIO TX2 isn’t just a top light—it’s a top performer. Designed for greenhouses and single-tier grows, this 800W fixture pushes 2400 µmol/s of balanced, full-spectrum output using the brand new S5 spectrum. With a lean profile that minimizes sun interference and a rugged POFF aluminum heatsink, the TX2 delivers 38% more light than its predecessor, without the bulk.

Running at 3.0 µmol/J efficacy and compatible with 208V–480V power systems, this fixture is ready to scale with your facility. Whether you’re upgrading a greenhouse or building out a single-level indoor run, TX2 gives you deep canopy penetration, high PPFD uniformity, and premium build quality designed for daily use in commercial conditions.

Is the PHOTOBIO TX2 energy-efficient?

Absolutely. With an efficacy of 3.0 µmol/J, the TX2 outpaces even top-tier HPS systems (which peak at 2.1 µmol/J). You’re getting more usable light per watt, less heat output, and a fixture optimized for long-term energy savings in professional grow operations.
