8 Best AC Infinity Grow Lights of 2026
Eight AC Infinity grow lights compared: IONBOARD S22 to S44 sealed boards and IONFRAME EVO3 to EVO8 bar lights with built-in scheduling.
By Ethan Cole
Updated November 3, 2026
AC Infinity is best known for tent fans and controllers, and its lights are built to plug into that system. There are two main lines: IONBOARD boards (S22 to S44) with Samsung LM301H diodes and IP-65 protection, and IONFRAME EVO bar lights with a schedule controller built in.
This guide compares eight AC Infinity lights. For other brands see Spider Farmer and Mars Hydro.
Safety note: grow tent lights draw from about 65 to 850 watts. Hang them from hangers rated for the fixture’s weight, plug them into a grounded outlet (GFCI-protected in a humid tent), keep drivers and cords off wet floors, and follow the maker’s hanging height. Many of these lights include far-red or infrared (730nm) diodes and a few include UV (395 to 405nm); do not look into them at close range. We describe what each maker lists; we do not promise growth or harvest results.

How We Evaluate AC Infinity Grow Lights
We did not grow plants under these lights. We compared manufacturer specifications and Amazon listing details, and ranked products by the WikiHomeLED Score, which adjusts the Amazon star rating for the number of ratings (ratings checked November 2, 2026). To qualify, a product had to be an AC Infinity grow light (IONBEAM supplemental bars excluded), with at least 20 ratings and a rating of 4.1 stars or higher. PPF, PPFD, efficacy (µmol/J), and coverage figures are as published by each seller and are not our measurements. Sellers often list a larger vegetative coverage and a smaller flowering coverage; we quote both where given. Several listings make yield claims; we do not repeat them. Mars Hydro TS, Spider Farmer SF, VIVOSUN LumaLight, VIPARSPECTRA P, and AC Infinity IONBOARD ratings are pooled across every size on one Amazon listing family, so the same rating can appear for different sizes. The full method is on our How We Review page. This is a single-brand guide, so the brand cap does not apply. IONBOARD sizes share one pooled rating.
Frequently Asked Questions
Is AC Infinity a good grow light brand?
Its IONBOARD line has about 1,050 ratings at 4.5 stars and its IONFRAME EVO lights 4.5 to 4.7 stars on smaller bases.
Do AC Infinity lights need a controller?
IONBOARD lights dim on their own; scheduling needs a controller. IONFRAME EVO lights have schedules built in.
What does IP-65 mean on the IONBOARD?
It is rated dust-tight and protected against water jets, useful in humid tents. Keep plugs and controllers dry.
Can AC Infinity lights work with other brands’ fans?
They can run on their own; the integration features need AC Infinity controllers.
Final Verdict
The IONFRAME EVO4 is the AC Infinity light to buy if you want scheduling without extra hardware. If you already run AC Infinity fans and a controller, the IONBOARD S22 or S24 joins that system at a lower cost.
