GrowPros 4ft 125W LED Under-Canopy Grow Light, Full Spectrum + IR, 2-Pack (Model 1)

4′ Under Canopy Grow Light | Full‑Spectrum + 5% IR | Model 1 (UCL‑125W) — Give your lower buds the light they deserve. Designed for racks and benches, these slim, durable bars drive even growth from top to bottom for bigger, higher‑quality harvests.

Unlock full-canopy performance: Target the shaded under-canopy to improve C & B-bud structure, density, and coloring. The optimized full spectrum with deep & far‑red supports veg through flower and can boost yields up to 60%.

Pro-grade light, effortless install: Each 4′ bar delivers 125W and 325 μmol/s through a wide 120° lens for uniform coverage. The built‑in driver, slim profile, and IP65 rating make it easy to mount, clean, and maintain in commercial environments.

Efficient, scalable control: Power and data daisy‑chain through a single IP65 connection (RJ12, 0–10V), minimizing cables and setup time. Run on 120–277V with passive thermal management for quiet, reliable operation.

Why Full‑Spectrum? It’s the go‑to choice for the entire growth cycle, delivering excellent density and color—especially alongside modern LEDs or HPS. Prefer a bloom push? Our Deep Red version specializes in flowering, but Full‑Spectrum is our best‑seller for balanced results.
