Photontek FAR-RED 50W Bar LED Grow Light – Daisy Chain 5ft

The PHOTONTEK 50W Far-Red LED Bar is a highly specialized supplemental light designed to extend the full spectrum of PHOTONTEK's main X / XT series fixtures by adding crucial far-red photons in the 701–750 nm range. This targeted spectral addition is engineered to harness the Emerson Enhancement Effect, which significantly boosts overall photosynthetic efficiency and the plant's light energy conversion rate, leading to improved growth. With a total output of 155 µmol/s PPF and high efficacy of 3.1 µmol/J, this 50W bar promotes desirable plant morphology, encouraging stem elongation and leaf expansion during the vegetative stage, and can be used in the later stages to accelerate the final bloom phase. Far-Red Optimization: Specifically outputs light in the 701–750 nm range, peaking at 730 nm. Emerson Effect: Leverages this principle to significantly boost photosynthetic efficiency and overall plant growth rate. Targeted Plant Response: Promotes desirable stem elongation and leaf expansion in veg and enhances final stages of bloom. Seamless Integration: Designed to magnetically attach to PHOTONTEK X / XT series fixture frames for easy supplemental use. High Efficiency & Scalable: Delivers 155 µmol/s at 3.1 µmol/J and is daisy-chainable up to 18 units. The bar is designed for seamless, plug-and-play integration, featuring an integrated 50W driver and the ability to magnetically attach directly onto the frames of PHOTONTEK X / XT fixtures. It boasts a passive cooling design for silent operation and an IP65 rating for use in high-humidity environments. For commercial and large-scale grows, the fixture offers daisy-chain connectivity, allowing up to 18 units to be linked in series. It is recommended to integrate a minimum of two to three bars depending on the size of the main fixture (e.g., 2 bars for X 465W PRO, 3 bars for X 1000W PRO) to ensure the ideal 10–20% far-red ratio when mixed with the full-spectrum output.
