{"product_id":"ac-infinity-ionboard-s33-260w-led-grow-light","title":"AC Infinity IONBOARD S33 260W LED Grow Light","description":"\u003cp\u003eThe AC Infinity IONBOARD S33 is a 260W full spectrum LED grow light designed for complete 3' x 3' grow coverage. It uses horticulture series Samsung LM301H diodes with an optimized full spectrum and algorithmically positioned LED layout to deliver strong canopy penetration and more uniform PAR distribution across the growing area.\u003c\/p\u003e\n\u003cp\u003eThe current generation S33 has been updated from the older 240W LM301B configuration still shown by some retailers. AC Infinity's current manufacturer listing specifies 260W output and Samsung LM301H diodes, so those are the specifications used for this product page.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower: 260W Full Spectrum LED\u003c\/li\u003e\n\u003cli\u003eCoverage: 3' x 3' 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\u003eThe fixture also includes integrated 0 to 100% dimming, fanless aluminum thermal management, IP65 protection, and compatibility with AC Infinity's UIS smart control ecosystem for scheduling, automated grow cycles, and app based control.\u003c\/p\u003e\n\u003ch3\u003e260W High Output Design\u003c\/h3\u003e\n\u003cp\u003eThe current IONBOARD S33 operates at 260 watts, providing the intensity needed for a complete 3' x 3' grow footprint.\u003c\/p\u003e\n\u003cp\u003eThis updated output gives the current S33 more power than the earlier 240W version while keeping the same compact square board format.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e the 260W current manufacturer specification is used here rather than the older 240W retailer data.\u003c\/p\u003e\n\u003ch3\u003eSamsung LM301H Diodes\u003c\/h3\u003e\n\u003cp\u003eThe current S33 uses Samsung LM301H horticulture series LEDs.\u003c\/p\u003e\n\u003cp\u003eThese diodes are designed specifically for horticultural applications and provide efficient full spectrum output suitable for every major stage of plant development.\u003c\/p\u003e\n\u003cp\u003eThe current light combines 3000K and 6500K white wavelengths for a broad spectrum that can be used from germination through flowering.\u003c\/p\u003e\n\u003ch3\u003eFull 3' x 3' Coverage\u003c\/h3\u003e\n\u003cp\u003eThe IONBOARD S33 is designed around a 3' x 3' grow footprint.\u003c\/p\u003e\n\u003cp\u003eIts square form factor closely matches common 3' x 3' grow tents, helping provide edge to edge lighting without requiring an oversized fixture.\u003c\/p\u003e\n\u003cp\u003eThis makes it well suited to growers who want one primary light for a complete medium sized tent.\u003c\/p\u003e\n\u003ch3\u003eOptimized Full Spectrum\u003c\/h3\u003e\n\u003cp\u003eThe S33 uses a horticultural full spectrum designed for use throughout the plant lifecycle.\u003c\/p\u003e\n\u003cp\u003eIts combination of warm and cool white wavelengths supports germination, seedlings, vegetative growth, and flowering.\u003c\/p\u003e\n\u003cp\u003eThis allows growers to keep the same fixture in place throughout the full grow instead of switching between separate veg and bloom lights.\u003c\/p\u003e\n\u003ch3\u003eAlgorithmically Positioned LEDs\u003c\/h3\u003e\n\u003cp\u003eAC Infinity positions the diodes according to an optimized pattern rather than a basic evenly spaced grid.\u003c\/p\u003e\n\u003cp\u003eThis arrangement is designed to improve PAR uniformity, edge coverage, canopy penetration, and overall light distribution.\u003c\/p\u003e\n\u003cp\u003eThe goal is to reduce excessive center intensity while delivering more useful light toward the perimeter of the 3' x 3' footprint.\u003c\/p\u003e\n\u003ch3\u003e0–100% Dimming\u003c\/h3\u003e\n\u003cp\u003eThe proprietary LED driver provides 0 to 100% brightness control.\u003c\/p\u003e\n\u003cp\u003eThe onboard dimmer adjusts intensity in 20% increments, allowing the fixture to be scaled to different plant stages.\u003c\/p\u003e\n\u003cp\u003eLower power settings can be used for seedlings and younger plants, while output can be increased as the canopy develops.\u003c\/p\u003e\n\u003ch3\u003eUIS Smart Controller Compatible\u003c\/h3\u003e\n\u003cp\u003eThe S33 is part of AC Infinity's UIS platform.\u003c\/p\u003e\n\u003cp\u003eConnecting the fixture to a compatible UIS controller unlocks 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\u003eWhen connected through a compatible UIS controller, the S33 can be managed through the AC Infinity app.\u003c\/p\u003e\n\u003cp\u003eGrowers can adjust schedules and lighting behavior remotely while integrating the fixture with other compatible AC Infinity equipment such as inline fans and circulation systems.\u003c\/p\u003e\n\u003cp\u003eThis allows the grow light to operate as part of a broader automated environment rather than as an isolated fixture.\u003c\/p\u003e\n\u003ch3\u003eDaisy Chain Support\u003c\/h3\u003e\n\u003cp\u003eThe proprietary driver includes connectivity for linking the S33 with additional lighting equipment.\u003c\/p\u003e\n\u003cp\u003eMultiple compatible fixtures can be paired through expansion accessories, helping growers scale their setup while keeping lighting controls centralized.\u003c\/p\u003e\n\u003cp\u003eExpansion dongles may be required depending on the final configuration.\u003c\/p\u003e\n\u003ch3\u003eFanless Thermal Management\u003c\/h3\u003e\n\u003cp\u003eThe IONBOARD S33 uses a fanless unibody aluminum board to dissipate heat.\u003c\/p\u003e\n\u003cp\u003eThe fixture body functions as a large passive heatsink, allowing heat to spread across the aluminum surface without requiring active cooling fans.\u003c\/p\u003e\n\u003cp\u003eThis reduces operating noise and eliminates one of the primary moving components found in actively cooled lighting fixtures.\u003c\/p\u003e\n\u003ch3\u003eIP65 Construction\u003c\/h3\u003e\n\u003cp\u003eAll major fixture components are sealed to IP65 standards.\u003c\/p\u003e\n\u003cp\u003eThis helps protect the light against dust and moisture exposure associated with humid grow tent environments.\u003c\/p\u003e\n\u003cp\u003eThe sealed design also helps maintain performance in areas where temperature and relative humidity are higher than normal household conditions.\u003c\/p\u003e\n\u003ch3\u003eCompact Square Design\u003c\/h3\u003e\n\u003cp\u003eThe S33 uses a square board format designed specifically around 3' x 3' spaces.\u003c\/p\u003e\n\u003cp\u003eOlder published specifications list the fixture at approximately 18.5\" x 18.5\", making it substantially smaller than the canopy area it is designed to illuminate.\u003c\/p\u003e\n\u003cp\u003eThis leaves room around the fixture for ventilation equipment and circulation inside the tent.\u003c\/p\u003e\n\u003ch3\u003eOptional Smart Controllers\u003c\/h3\u003e\n\u003cp\u003eThe S33 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
