ThinkGrow’s ICL-300 is a 4‑foot inner‑canopy LED bar intended as supplemental lighting to reach shaded mid and lower plant sites. It integrates a 120 W driver (100–277 VAC) and drives diodes on three sides for roughly 300‑degree emission. Output is rated above 314 µmol/s PPF, with an L90 lifetime over 54,000 hours and an IP56 moisture‑resistant build. Dimensions are 46.21 × 3.60 × 2.64 in (117.4 × 9.1 × 6.7 cm) and weight is 2.8 kg. The bar offers four spectrum channels (full‑spectrum white, deep red, far red, and UV) for flexible canopy supplementation. Typical deployment is one bar in a 2×4 ft area and one to two bars in a 4×4 ft area; the optional TSD‑1 stand simplifies in‑canopy placement and height adjustment.
