iLuminar 780W iLogic 121 LED Grow Light. Full Spectrum, 120–277V

iLuminar 780W Full-Spectrum LED Grow Light for DE-HPS Retrofit The iLogic 121 runs 780W on a 120–277V input across a full-spectrum LED diode mix. PPF reaches 2,100 µmol/s at 2.7 µmol/J. It is a DE-HPS replacement engineered to match the footprint and hanging height of legacy 1000W DE-HPS fixtures. Energy consumption drops 32% with a 50,000-hour life rating. The 0–10V dimming integrates with standard commercial control gear. What the iLogic Brings When Swapping Out DE-HPS A 1-to-1 DE-HPS-to-LED swap looks simple on paper. The practical wins show up over the first 18 months: no monthly bulb degradation, no ballast warm-up, less radiant heat at the canopy. the fixture delivers 2,100 µmol/s PPF at lower wall draw than a 1000W HPS. Growers typically hang the fixture 24–36 inches above canopy in greenhouse retrofits. Dim via 0–10V to balance flux across multi-fixture rows. Key Features 780W Full-Spectrum LED: Drop-in 1-to-1 replacement for 1000W DE-HPS at 32% lower wall draw. 2,100 µmol/s PPF at 2.7 µmol/J: Solid commercial-grade flux for greenhouse and indoor flower rooms on a 120–277V input. 0–10V Dimming: Integrates with TrolMaster, GrowFlux, Autopilot, and standard commercial control gear without proprietary dimmers. DE-HPS Footprint Match: Hangs in the same place a legacy DE-HPS occupied — no truss redesign or fixture re-spacing for retrofit installs. 50,000-Hour Lifespan: Replaces five to seven 1000W HPS bulb cycles, removing the monthly degradation curve from the cycle math. 32% Energy Savings vs HPS: Reduces wall draw and canopy heat load enough to shrink room AC sizing on retrofit projects.
