AC Infinity IONFRAME EVO4 300W LED Grow Light – Full Spectrum Bar Light for 3x3 Coverage (AC-IF4K)

The AC Infinity IONFRAME EVO4 is a 300W full-spectrum bar-style LED grow light engineered for indoor cultivation environments. Built around Samsung LM301H EVO diodes — the latest generation in horticultural lighting — it delivers high-intensity, energy-efficient light output across a 3 x 3 ft canopy with exceptional uniformity and deep penetration.

Algorithmically spaced diodes across the bar-style fixture eliminate hotspots and ensure consistent light distribution from edge to edge, supporting more uniform plant development throughout the canopy.

Samsung LM301H EVO Diodes

At 3.14 µmol/J per diode, the LM301H EVO outperforms previous-generation LM301H, LM301B, and Bridgelux 3030 chips. The full spectrum is completed by Seoul 395nm UV, OSRAM 660nm red, and OSRAM 730nm far-red diodes, supporting all stages of the plant growth cycle from seedling through to late-stage development.

Bar-Style Design for Even Coverage

The multi-bar form factor distributes light more evenly across the canopy compared to traditional single-source LED fixtures. This improves edge-to-edge coverage, increases canopy penetration, and reduces uneven development across the grow space. The open design also supports passive heat dissipation, helping maintain lower fixture temperatures.

Removable Driver & Passive Cooling

The passive cooling LED driver is fully removable, allowing remote mounting away from the fixture to better manage heat distribution within the grow environment. The steel and aluminium build supports magnetic mounting and carries an IP-65 waterproof rating for use in humid conditions.

Smart Control & UIS Ecosystem Integration

Includes a schedule controller with 10 brightness levels, sunrise/sunset dimming, and daily cycle programming. As part of the AC Infinity UIS platform, the IONFRAME EVO4 integrates with compatible UIS controllers (such as the CONTROLLER 69 PRO) for WiFi app control, automation, and grow recipes. Supports daisy-chaining of up to 80 units via splitter dongles (sold separately).
