AC Infinity IONBOARD S22 115W LED Grow Light

The AC Infinity IONBOARD S22 is a compact 115W full spectrum LED grow light designed for 2' x 2' grow spaces. It uses horticulture series Samsung LM301H LEDs with algorithmically positioned diodes to deliver uniform PAR coverage and strong canopy penetration throughout the plant growth cycle.

A fanless unibody aluminum construction passively dissipates heat, while IP65 sealed components help protect the fixture in warm, humid grow environments. Built in dimming provides straightforward intensity control, or the S22 can connect to compatible AC Infinity UIS controllers for automated schedules, grow cycles, and app based control.

Samsung LM301H LEDs

The current IONBOARD S22 uses Samsung LM301H horticulture LEDs selected for efficient full spectrum plant lighting.

The fixture combines 3000K and 6500K white diodes to provide light suitable for germination, vegetative growth, and flowering.

Algorithmically Positioned Diodes

AC Infinity doesn't simply arrange the LEDs in an evenly spaced grid.

The diode layout is algorithmically positioned across the board to create a more uniform PAR map and improve light penetration into the canopy.

This helps reduce excessive intensity in the center of the footprint while providing more usable light toward the edges.

2' x 2' Coverage

The IONBOARD S22 is designed around a compact 2' x 2' grow footprint, making it particularly well suited for smaller grow tents and indoor gardens.

Its approximately 12" square fixture dimensions also leave room around the light for ventilation and other tent equipment.

115W Power

The current S22 is rated at 115 watts, providing a compact lighting solution without the power requirements of larger fixtures.

Important: Some older retailer listings identify the IONBOARD S22 as a 100W fixture using LM301B diodes. AC Infinity's current manufacturer listing specifies 115W and Samsung LM301H diodes, so those current manufacturer specifications are used for this product page.

Full Spectrum Output

The S22 is designed to support plants throughout the complete growth cycle rather than requiring separate vegetative and flowering fixtures.

Its full spectrum output supports seedlings and germination through vegetative development and flowering.

0–100% Dimming

The proprietary AC Infinity LED driver provides 0 to 100% brightness control.

The onboard control knob adjusts intensity in 20% increments, allowing growers to reduce output for younger plants and increase intensity as their lighting requirements develop.

UIS Smart Controller Compatible

The IONBOARD S22 is part of AC Infinity's UIS ecosystem.

Connecting the fixture to a compatible AC Infinity smart controller unlocks additional automation capabilities such as lighting schedules, automated grow cycles, app control, and coordinated environmental equipment control.

Compatible controller options include the Controller 69 Pro, Controller 69 Pro+, and Controller AI+.

Daisy Chain Ready

The S22's driver includes connectivity for linking lighting equipment and integrating additional fixtures into a larger control system.

Expansion accessories may be required depending on the configuration.

This provides an upgrade path for growers who begin with a single S22 and later expand their lighting setup.

Fanless Unibody Design

Instead of relying on active cooling fans, the S22 uses its unibody aluminum board as a passive heatsink.

Heat is dissipated across the fixture body, eliminating cooling fan noise and reducing the number of moving components that can wear out over time.

IP65 Rated

The fixture's components are sealed to IP65 standards.

This construction is designed to maintain performance in the elevated humidity and temperatures commonly encountered inside grow tents and indoor cultivation environments.

Optional Smart Controllers

The S22 can be purchased on its own or bundled with a compatible AC Infinity UIS smart controller for added automation.

Controller 69 Pro — Independent programming UIS controller.

Controller 69 Pro+ — Independent programming UIS controller with 8-port connectivity for larger setups.

Controller AI+ — Environmental controller with AI powered learning and dynamic level adjusting.
