Optimize Every Harvest with PHOTOBIO TX S4 Spectrum Designed for Both Human and Plant Health

Get to Know the PHOTOBIO TX 680 Watt S4 Full Spectrum LED Grow Light

The PHOTOBIO TX is a commercial-grade LED top light built for greenhouses and indoor cultivation, delivering 1768 µmol/s of photon output at 2.6 µmol/J efficiency. Its thin, linear design minimizes sun interference in greenhouses while providing better canopy access indoors, ensuring optimal light distribution without wasted space. The closed-loop heat pipe cooling system rapidly dissipates heat, keeping operating temperatures low and fixture longevity high. With DLC certification for rebate eligibility, this high-efficiency LED fixture is designed to maximize ROI while creating a better work and grow environment.

Is the PHOTOBIO TX Energy-Efficient?

Absolutely. At 2.6 µmol/J, the PHOTOBIO TX surpasses traditional HPS systems (1.3–2.1 µmol/J) in light efficiency, energy savings, and longevity. With optional AC and DC power distribution tree compatibility, growers can link multiple fixtures on a single power drop, significantly reducing electrical infrastructure costs while maximizing yield potential.

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.
