Samsung LM301H vs Osram — Commercial Horticulture LED Comparison

📌 Key Takeaway: The sweet spot for commercial grow lights in 2026 is 480-650W bar-style with Samsung LM301H EVO (3.14 μmol/J) + Osram 660nm reds, priced $0.55-0.75/W FOB. Full spectrum white (3000K + 5000K mix) with supplemental 660nm deep red and 730nm far red outperforms blurple-only and broad-spectrum-only. Bar lights with daisy-chain RJ12/RJ45 dimming dominate commercial installations for uniform canopy coverage.

🌱 Spectrum Formula: Optimal commercial spectrum for full-cycle (veg → flower): 70% white (3000K + 5000K mix, Samsung LM301H), 20% 660nm deep red (Osram), 5% 730nm far red (Emerson effect for flowering), 5% 450nm blue. Avoid "blurple" (pure red+blue) — lower yield, harder plant inspection. UV-A (385nm) supplementation gaining traction for trichome/terpene enhancement but adds $0.05-0.10/W.
