AC Infinity IONFRAME EVO4 Bar-Style Commercial LED Grow Light 300W

Next-Gen Samsung LM301H EVO Diodes (3.14 μmol/J) with Removable Driver & Integrated Sunrise/Sunset Scheduling Controls

The AC Infinity IONFRAME EVO4 (AC-IF4K) is a 300W bar-style LED grow light engineered for high-density 3×3 ft flowering footprints (4×4 ft vegetative coverage). Outfitted with 896 total diodes, headlined by genuine Samsung LM301H EVO chips rated at an efficiency of 3.14 μmol/J, the IONFRAME EVO4 outperforms previous-generation LM301B, LM301H, and Bridgelux 3030 chips by emitting a higher blue-spectrum ratio and greater photon output per watt.

Featuring an open bar architecture, the IONFRAME EVO4 algorithmically spaces diodes along parallel light bars to eliminate centre hotspots while maximising uniform edge-to-edge PAR coverage up to 1819 PPFD. For optimal environmental thermal management, the heavy-duty SOSEN-320W driver can be detached and mounted remotely outside the grow tent. The included Schedule Controller provides 10 dimming levels, daily cycle timers, and a gradual sunrise/sunset mode that mimics natural solar progression. As part of the UIS™ platform, it links via daisy-chaining (up to 80 lights) or connects to smart controllers for remote Wi-Fi app automation.

Key Architectural Differences: IONFRAME EVO4 vs. IONBOARD S-Series

• Bar-Style Form Factor vs. Single Unibody Board: Uses spaced parallel light bars instead of a solid aluminium panel, improving passive airflow and heat dissipation while reducing canopy centre hot spots.
• Samsung LM301H EVO Diodes (3.14 μmol/J): Upgrades standard LM301H chips to the EVO series, delivering higher PPE efficiency and enriched blue light for tighter node spacing.
• Targeted UV & Specialised Red Array: Integrates (4) 395nm UV diodes, (28) OSRAM 660nm deep red, and (4) OSRAM 730nm far-red chips alongside 3000K/5000K white diodes for enhanced resin and flower development.
• Removable SOSEN Driver: Allows the high-wattage power supply to be detached and hung outside the grow enclosure, directly mitigating ambient temperature build-up inside the tent.
• Built-In Digital Schedule Controller: Features a digital controller with 10-step brightness control, cyclic timers, and sunrise/sunset ramping straight out of the box.

Key Product Features

• Samsung LM301H EVO Performance: Emits intense PAR spectrums with diode efficiency reaching 3.14 μmol/J to accelerate growth rates during all developmental phases.
• Full-Spectrum UV-to-Far-Red Mix: Combines 3000K and 5000K white light with 395nm UV, 660nm deep red, and 730nm far-red OSRAM LEDs for a complete natural sunlight spectrum.
• Removable Remote-Mount Driver: Modular SOSEN 320W power driver detaches easily from the frame to reduce grow tent heat load.
• Smart Sunrise & Sunset Dimming: Built-in scheduler simulates natural dawn and dusk transitions, gradually ramping light intensity to reduce plant stress.
• Commercial Scale Daisy-Chaining: Connects with up to 80 grow fixtures using RJ11/RJ12 splitter dongles for centralised multi-light scheduling.
• IP-65 Waterproof Construction: Steel and aluminium framework with sealed electronics resists moisture, high humidity (35–85% RH), and dust.

Comprehensive Technical Specifications

Real-World Applications

• 3×3 Flower Canopy Lighting: Delivers high PPFD and deep penetration across a dense 3×3 ft flowering space.
• Temperature-Sensitive Grow Rooms: Ideal for setups where reducing ambient heat is critical by placing the removable SOSEN driver outside the room.
• UIS Ecosystem Automation: Pairs directly with CONTROLLER 69 PRO to sync lighting schedules with inline fan speed, humidity levels, and VPD targets via the AC Infinity app.
