{"product_id":"ac-infinity-ionboard-s44-430w-led-grow-light","title":"AC Infinity IONBOARD S44 430W LED Grow Light","description":"\u003cp\u003eThe AC Infinity IONBOARD S44 is a 430W full spectrum LED grow light designed for complete 4' x 4' grow coverage. Built around horticulture series Samsung LM301H diodes, the S44 combines optimized full spectrum output, algorithmically positioned LEDs, passive cooling, and smart control compatibility in a compact board style fixture.\u003c\/p\u003e\n\u003cp\u003eThe current generation S44 has been updated from the older 400W LM301B version still shown by some retailers. AC Infinity's current manufacturer listing specifies 430W output and Samsung LM301H diodes, so those are the specifications used for this product page.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower: 430W Full Spectrum LED\u003c\/li\u003e\n\u003cli\u003eCoverage: 4' x 4' Grow Area\u003c\/li\u003e\n\u003cli\u003eDiodes: Samsung LM301H\u003c\/li\u003e\n\u003cli\u003eControls: 0–100% Dimming + UIS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWith integrated 0 to 100% dimming, IP65 protection, fanless aluminum construction, and UIS smart controller compatibility, the S44 is designed for growers who want full cycle lighting and automation across a standard 4' x 4' tent.\u003c\/p\u003e\n\u003ch3\u003e430W High Output Design\u003c\/h3\u003e\n\u003cp\u003eThe current IONBOARD S44 operates at 430 watts, providing the intensity required for a complete 4' x 4' grow footprint.\u003c\/p\u003e\n\u003cp\u003eThis updated power level gives the current S44 more output than the previous 400W version while retaining the same compact board style form factor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e the current 430W manufacturer specification is used here rather than older 400W retailer data.\u003c\/p\u003e\n\u003ch3\u003eSamsung LM301H Diodes\u003c\/h3\u003e\n\u003cp\u003eThe current S44 uses Samsung LM301H horticulture series LEDs.\u003c\/p\u003e\n\u003cp\u003eThese diodes are designed specifically for plant lighting applications and provide efficient full spectrum output suitable for germination, vegetative development, and flowering.\u003c\/p\u003e\n\u003cp\u003eThe current fixture combines 3000K and 6500K white diodes to provide broad spectrum coverage throughout the complete growth cycle.\u003c\/p\u003e\n\u003ch3\u003eFull 4' x 4' Coverage\u003c\/h3\u003e\n\u003cp\u003eThe IONBOARD S44 is designed for a 4' x 4' grow footprint.\u003c\/p\u003e\n\u003cp\u003eIts square format aligns closely with one of the most common indoor tent sizes, allowing one fixture to serve as the primary light source for the entire canopy.\u003c\/p\u003e\n\u003cp\u003eThe optimized diode placement is intended to provide useful edge to edge intensity rather than concentrating excessive light only at the center.\u003c\/p\u003e\n\u003ch3\u003eOptimized Full Spectrum\u003c\/h3\u003e\n\u003cp\u003eThe S44 uses a horticultural full spectrum designed for use through all major plant stages.\u003c\/p\u003e\n\u003cp\u003eIts warm and cool white output supports germination, seedlings, vegetative growth, and flowering.\u003c\/p\u003e\n\u003cp\u003eThis allows growers to keep one fixture installed throughout the complete cycle rather than switching between separate veg and bloom lights.\u003c\/p\u003e\n\u003ch3\u003eAlgorithmically Positioned LEDs\u003c\/h3\u003e\n\u003cp\u003eAC Infinity positions the S44's LEDs according to an optimized layout rather than a simple evenly spaced grid.\u003c\/p\u003e\n\u003cp\u003eThe arrangement is designed to improve PAR uniformity, edge to edge coverage, canopy penetration, and overall light distribution.\u003c\/p\u003e\n\u003cp\u003eThis helps reduce center hot spots and improve usable light levels around the perimeter of the 4' x 4' canopy.\u003c\/p\u003e\n\u003ch3\u003e0–100% Dimming\u003c\/h3\u003e\n\u003cp\u003eThe proprietary LED driver allows 0 to 100% brightness control.\u003c\/p\u003e\n\u003cp\u003eThe integrated control knob adjusts output in 20% increments, making it easy to lower intensity during early growth and increase power as plants mature.\u003c\/p\u003e\n\u003cp\u003eThis allows the same fixture to serve different growth stages without changing hanging equipment or replacing the light.\u003c\/p\u003e\n\u003ch3\u003eUIS Smart Controller Compatible\u003c\/h3\u003e\n\u003cp\u003eThe IONBOARD S44 is part of AC Infinity's UIS platform.\u003c\/p\u003e\n\u003cp\u003eWhen connected to a compatible controller, growers can access additional automation features including lighting schedules, automated grow cycles, environmental triggers, app control, remote monitoring, and advanced programming.\u003c\/p\u003e\n\u003cp\u003eCompatible options include the Controller 69 Pro, Controller 69 Pro+, and Controller AI+.\u003c\/p\u003e\n\u003ch3\u003eAC Infinity App Control\u003c\/h3\u003e\n\u003cp\u003eWith a compatible UIS controller, the S44 can be managed through the AC Infinity app.\u003c\/p\u003e\n\u003cp\u003eGrowers can adjust schedules, automation, and lighting behavior remotely while coordinating the fixture with compatible inline fans, circulation fans, and other UIS equipment.\u003c\/p\u003e\n\u003cp\u003eThis allows the grow light to function as part of a larger environmental automation system.\u003c\/p\u003e\n\u003ch3\u003eDaisy Chain Support\u003c\/h3\u003e\n\u003cp\u003eThe S44's proprietary driver includes connectivity for expanding the lighting setup.\u003c\/p\u003e\n\u003cp\u003eAdditional compatible LED fixtures can be linked using AC Infinity expansion accessories, allowing growers to scale beyond one 4' x 4' area while maintaining centralized control.\u003c\/p\u003e\n\u003cp\u003eExpansion dongles may be required depending on the configuration.\u003c\/p\u003e\n\u003ch3\u003eFanless Thermal Management\u003c\/h3\u003e\n\u003cp\u003eThe IONBOARD S44 uses a fanless unibody aluminum board to dissipate heat.\u003c\/p\u003e\n\u003cp\u003eThe fixture body acts as a passive heatsink, spreading heat across the aluminum surface without relying on active cooling fans.\u003c\/p\u003e\n\u003cp\u003eThis reduces operating noise, moving parts, fan maintenance, and potential fan failure.\u003c\/p\u003e\n\u003ch3\u003eIP65 Construction\u003c\/h3\u003e\n\u003cp\u003eThe fixture is built to IP65 standards.\u003c\/p\u003e\n\u003cp\u003eThis helps protect internal components against dust and moisture exposure commonly found in humid indoor grow environments.\u003c\/p\u003e\n\u003cp\u003eThe sealed design makes the S44 better suited to tents and grow rooms than unsealed household lighting equipment.\u003c\/p\u003e\n\u003ch3\u003eCompact Board Design\u003c\/h3\u003e\n\u003cp\u003eOlder published specifications list the S44 fixture at approximately 23.62\" x 23.62\", giving it a relatively compact physical footprint compared with the 4' x 4' canopy it is designed to illuminate.\u003c\/p\u003e\n\u003cp\u003eThis leaves room around the fixture for air circulation, ducting, and other grow tent equipment.\u003c\/p\u003e\n\u003ch3\u003eOptional Smart Controllers\u003c\/h3\u003e\n\u003cp\u003eThe S44 can be purchased on its own or bundled with a compatible AC Infinity UIS smart controller for added automation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eController 69 Pro\u003c\/strong\u003e — Independent programming UIS
