AC Infinity IONBOARD S24 220W LED Grow Light

The AC Infinity IONBOARD S24 is a 220W full spectrum LED grow light designed for complete 2' x 4' coverage. Built around a fanless aluminum board, algorithmically positioned LEDs, and an optimized horticultural spectrum, the S24 is designed to deliver uniform light distribution and strong canopy penetration throughout the full growth cycle.

The current generation S24 uses AC Infinity's newer proprietary diode platform rather than the older Samsung LM301B configuration found in previous retailer listings. The current manufacturer version also increases fixture power from 200W to 220W, while retaining the same 2' x 4' coverage class.

• Power: 220W Full Spectrum LED
• Coverage: 2' x 4' Grow Area
• Spectrum: 3000K + 6500K
• Controls: 0–100% Dimming + UIS

Integrated dimming provides manual control from 0 to 100%, while compatibility with AC Infinity's UIS smart controllers unlocks automated schedules, grow cycles, advanced programming, and app based control.

220W High Output Design

The current IONBOARD S24 operates at 220 watts, providing high intensity full spectrum lighting for 2' x 4' growing areas.

This updated power level gives the S24 additional output compared with earlier 200W versions while keeping the fixture in the same compact board style format.

Important: the current 220W manufacturer specification is used here rather than the older 200W retailer listing.

Full 2' x 4' Coverage

The S24 is designed specifically for a 2' x 4' grow footprint.

Its rectangular layout closely matches one of the most common grow tent sizes, making it well suited to smaller flowering tents, propagation rooms, and compact indoor gardens.

The fixture's diode layout is engineered to provide useful light across the entire footprint rather than concentrating excessive intensity only in the center.

Optimized Full Spectrum

The current IONBOARD S24 uses a combination of 3000K and 6500K white diodes.

This broad spectrum is designed to support germination, seedlings, vegetative growth, and flowering.

Using one fixture through the full growth cycle eliminates the need to change lighting systems between vegetative and flowering stages.

Algorithmically Positioned Diodes

AC Infinity arranges the LEDs according to an optimized distribution pattern rather than a simple uniform grid.

The goal is more uniform PAR distribution, better edge to edge coverage, reduced center hot spots, and deeper canopy penetration.

This helps more of the 2' x 4' canopy receive useful light at comparable intensity levels.

Maximum Efficiency Diode Platform

The current S24 uses AC Infinity's proprietary high efficiency diode design.

These LEDs are engineered to maximize light output and electrical efficiency while maintaining the fixture's compact dimensions.

This is an important update from older S24 product information that listed Samsung LM301B LEDs. The manufacturer now describes the current generation simply as proprietary optimized diodes, so the newer specification is reflected here.

Advanced Thermal Management

The S24 uses a fanless unibody aluminum board as its primary heat sink.

The current generation also incorporates an enhanced thermal design intended to improve heat dissipation across the fixture.

By moving heat away from the LEDs without active cooling fans, the fixture reduces moving parts, operating noise, fan maintenance, and localized heat buildup.

0–100% Dimming

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

The integrated control knob adjusts output in 20% increments, allowing growers to match intensity to plant development.

Lower levels can be used for younger plants, while full output can be applied once the canopy requires higher light intensity.

UIS Smart Controller Compatible

The IONBOARD S24 is part of AC Infinity's UIS ecosystem.

When connected to a compatible controller, growers can access features such as automated light schedules, grow cycle programming, environmental triggers, app control, remote monitoring, and advanced automation.

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

AC Infinity App Integration

With a compatible UIS smart controller, the S24 can be managed through the AC Infinity app.

This allows lighting schedules, intensity settings, and other automation features to be controlled remotely over WiFi.

The grow light can also be coordinated with compatible fans and other UIS equipment as part of a broader environmental control system.

Daisy Chain Ready

The S24's driver includes connectivity for expanding the lighting system.

Multiple fixtures can be paired through compatible expansion accessories, allowing growers to scale beyond a single 2' x 4' fixture while maintaining centralized control.

Expansion dongles may be required depending on the chosen configuration.

IP65 Protection

The fixture is built to IP65 standards.

This helps protect its internal components from dust and moisture exposure commonly encountered inside humid growing environments.

The IP65 construction makes the S24 better suited to grow tents and controlled horticultural environments than unsealed consumer lighting products.

Unibody Aluminum Construction

The light is built around a rigid aluminum board that functions as both the structural body and passive heatsink.

This design keeps the fixture relatively thin while helping distribute heat evenly across its surface.

It also eliminates the need for a separate fan housing or bulky active cooling assembly.

Optional Smart Controllers

The S24 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.
