AC Infinity IONBOARD S33 Full-Spectrum LED Grow Light 260W

High-Efficiency Samsung LM301H Diodes (3×3 ft Coverage) with Algorithmically Positioned PAR Mapping & UIS™ Ecosystem Integration

The AC Infinity IONBOARD S33 (AC-IBS33) is a premium 260W full-spectrum LED grow light engineered to maximise crop yield and canopy penetration in 3×3 ft grow tents. Powered by 640 Samsung LM301H horticulture-grade diodes, the light delivers a high efficacy of 2.7 μmol/J and a peak output of 1788 PPFD. Diodes are algorithmically arranged across the unibody aluminium board to eliminate cold spots and provide edge-to-edge PAR distribution.

Built on a passive-cooling, fanless aluminium heat sink, the IONBOARD S33 operates completely silently while protecting diode longevity. All components are IP-65 sealed against high humidity, dust, and heat inside closed grow spaces. The included IB-240 driver features a manual 0–100% dimming knob (adjustable in 20% steps) and daisy-chain capability. As part of the AC Infinity UIS™ (Universal Infinity System) platform, it connects directly to smart controllers for automated light cycles, scheduling, and remote mobile app control over Wi-Fi.

Key Features & Benefits

• Samsung LM301H LED Diodes: Built with 640 premium Samsung white diodes (3000K and 6500K) supplemented with 660nm deep red and 730nm far-red LEDs for complete plant stage coverage.
• Algorithmically Positioned PAR Map: Diodes are spaced to ensure uniform light coverage across a full 3×3 ft canopy, driving light deeper into lower leaves without scorching central tops.
• UIS™ Smart Controller Ecosystem: Integrates seamlessly with AC Infinity smart controllers and expansion dongles to enable automated schedules, environmental triggers, and smartphone management.
• IP-65 Water & Heat Resistance: Encapsulated electronic board withstands high-humidity grow tent environments (35–85% RH) and operating temperatures up to 140°F.
• Fanless Unibody Aluminium Heat-sink: Heavy-duty, 0.43-inch aluminium substrate dissipates heat passively without noisy internal fans or moving parts.
• Integrated Step-Dimmer Knob: Manual brightness control (0%, 20%, 40%, 60%, 80%, 100%) permits easy output adjustments during seedling, vegetative, and bloom phases.
