FAQs
How does this compare to other 400W lights?
The Ionboard S44 stands out with its genuine Samsung LM301B diodes, high efficiency of 2.75 µmol/J, and a durable unibody build. Its seamless integration into the greater AC Infinity ecosystem provides a level of automation and control that many competitors lack.
Is the Ionboard S44 suitable for all growth stages?

What does the IP65 rating mean for growers?
The IP65 rating signifies that the light is completely dust-tight and protected against low-pressure water jets. This makes it exceptionally safe and reliable for use in the high-humidity environments typical of grow tents and rooms, protecting the internal components from moisture damage.
What's included in the box?
The package includes the Ionboard S44 LED light, a complete hanging kit with adjustable ratchet hangers, a power cord, and the user manual. Smart controllers like the AC Infinity Controller AI+ that unlock advanced features are sold separately.
What does the two-year warranty cover?
AC Infinity's two-year warranty covers manufacturing defects and component failures that occur under normal operating conditions. It ensures your investment is protected against unforeseen issues with the fixture.
How can I get the most out of the AC Infinity ecosystem?
To maximize your results, consider pairing the Ionboard S44 with other AC Infinity equipment like inline fans and controllers. This creates a fully automated environment where temperature and humidity trigger responses from your devices. For a deeper dive, check out our in-depth guide to AC Infinity systems.
