GrowPros 4ft 125W Under-Canopy Grow Light, Full Spectrum + IR, 8-Pack, Model 1

4′ Under-Canopy Grow Light | Full‑Spectrum + 5% IR | Model 1 (8‑pack) — Turn shaded lower growth into premium yield. These 4' interlighting bars flood the under-canopy with balanced spectrum and IR to awaken lower bud sites, drive even development from top to bottom, and elevate overall crop quality.

Why growers choose it: Up to 60% yield boost with improved C & B-bud structure, density, and color. An optimized full spectrum + deep/far red supports veg through flower and helps maximize cannabinoids and terpenes for potent, aromatic harvests.

Built for commercial reliability: Slim 1‑bar design with a 120° lens and built‑in driver for fast installs; IP65 for easy cleaning and protection from IPM sprays; compact and lightweight for easy work between trellis layers; passive cooling and a 5‑year limited warranty for long‑term performance.

Simple, scalable control: Power and data daisy‑chain on a single IP65 connection (RJ12 0–10V). Pair with Trolmaster, GrowPros, or AC Infinity controllers (adapter may be required). Note: a controller is required to dim—otherwise lights run at 100%.

What’s included: (8) 4′ under‑canopy bars. Optional add‑ons: 120V or 240V power cord with built‑in RJ12, pod stands, and 3′ interconnect cables (sold separately).

Full‑Spectrum vs. Deep Red: This Full‑Spectrum model is the go‑to for the entire growth cycle and pairs excellently with both LED and HPS. Deep Red is more specialized for flowering and older LED fixtures; over 70% of customers choose Full‑Spectrum for under‑canopy lighting.

Key specs (per bar): 125W, 325 μmol/s PPF; high PPFD performance at close range; 120–277V, PF 0.9; 48" x 2.6" x 3.2"; IP65; L90 > 36,000 hrs.
