Boost Photosynthetic Efficiency with the Photontek 50W FAR-RED LED Bar for Next-Level Growth

Built for serious growers using the Photontek X or XT Series, this 50W FAR-RED LED Bar adds a powerful 701–750 nm spike that takes your spectrum from full to full-throttle. Whether you're running CO₂-rich commercial rooms or dialing in stretch during veg, this bar unlocks the Emerson Enhancement Effect—meaning faster growth, better light penetration, and fuller canopy development when you need it most.

Designed to fit seamlessly onto your existing fixture frames, it's independently powered, daisy-chainable, and engineered to deliver precise far-red exposure without frying your crop. Use it in veg to stretch, early flower to bulk up spacing, or late bloom to push photosynthesis over the finish line. Just follow the application guide and install 2–3 bars based on your fixture and footprint size.

Is the Photontek 50W FAR-RED LED Bar energy-efficient?

This bar delivers 148 µmol/s in the 701–750 nm range with a 13 µmol/s contribution in 600–700 nm, giving it a total output efficiency of ~3.2 µmol/J. That’s miles ahead of old HPS setups (1.3–1.7 µmol/J) and a clear upgrade even from premium DE HPS units. You get more usable light per watt, right where your plants can use it.
