THROUGH THE Cultivator's LENS Highlights

  • You are lighting a 4x4 grow tent because underpowered fixtures create hotspots in the center while leaving the edges weak.
  • You are managing germination, vegetative growth, and flowering because the full spectrum white diodes, 660 nm red, and 730 nm far-red cover every stage.

  • The dimmer knob sets intensity from 20% to 100% in 20% steps to match each growth stage.
  • The black anodized aluminum unibody board cools passively with no fans or noise.
  • The IP65 seal keeps out moisture and dust in humid tents.

  • Growers who pair the light with an AC Infinity smart controller say they appreciate the easy Wi-Fi app control and automated scheduling.
  • Users running humid tents report that the IP65 seal holds up reliably against moisture and dust.

AC Infinity Ionboard S44 430W Full Spectrum LED Grow Light

A 4×4 ft. tent is where underpowered lights show their limits: strong in the center, weak at the edges, and nowhere near enough for dense flowers. The AC Infinity Ionboard S44 spreads 1,024 algorithmically spaced Samsung LM301H diodes across a 23.62 × 23.62 in. board, delivering 2034 PPFD at 430W. That gives even coverage across a 4×4 grow tent without hotspots.

Warm 3000K and cool 6500K white diodes, plus 660 nm red and 730 nm far-red, give the S44 a full spectrum for germination, veg and flower at 2.75 µmol/J efficiency. The black anodized aluminum unibody board cools passively with no fans or noise, and its IP65 seal keeps out moisture and dust in humid tents. The separate IB-400 driver has a dimmer knob that sets intensity from 20% to 100% in 20% steps.

Turn the knob to UIS and the S44 hands control to an AC Infinity smart controller (sold separately). That adds scheduling, automation and Wi-Fi app control across the AC Infinity ecosystem.

Spectrum

AC Infinity Ionboard S44 full spectrum LED grow light spectrum chart

The Ionboard S44 builds its spectrum from 1,024 Samsung LM301H diodes. Warm 3000K and cool 6500K white channels form a broad photosynthetic base for every growth stage. 660 nm deep red diodes support flowering and fruiting, and 730 nm far-red works with that red to round out the spectrum, delivering consistent coverage across the full 4 × 4 ft. footprint.

Warranty

The AC Infinity Ionboard S44 is covered by a 2-year limited manufacturer warranty from the original date of purchase.

Frequently Asked Questions

What size grow tent is the Ionboard S44 best for? +

The Ionboard S44 is built for a 4 × 4 ft. footprint, a direct match for the AC Infinity CLOUDLAB 844 grow tent. For 3 × 3 ft. spaces, the AC Infinity Ionboard S33 is the better fit.

How do I hang the Ionboard S44? +

Insert the included steel hooks into the slotted end caps, then slide one of your tent's support poles under the hooks and set the pole back into the frame. Two people are recommended for this step. You can also hang it from the included rope clip hangers for adjustable height.

How high should I hang the Ionboard S44 above my plants? +

AC Infinity's starter guide recommends about 1.5 ft. above the canopy, with intensity at 40% for seedlings, 80% for veg and 100% for flower. If you prefer a fixed position, hang it at peak height and run it at 100% throughout. Watch your plants' response and adjust as needed.

How does the dimmer knob work? +

The knob on the LED driver sets brightness from 20% to 100% in 20% steps. Turning it to the UIS position switches the light off, or passes control to a connected AC Infinity smart controller such as the AC Infinity Controller AI+ for scheduling and automation.

What does the IP65 rating mean for growers? +

IP65 means the board is dust-tight and protected against low-pressure water jets from any direction. That makes the Ionboard S44 well suited to the high humidity of grow tents and rooms, where condensation and misting are common.

What is the actual power draw? +

The Ionboard S44 draws 430W at full brightness: 3.60 A at 120V, 1.80 A at 240V and 1.56 A at 277V. Dimming with the knob or a smart controller reduces power use for seedlings and veg.

How can I get the most out of the AC Infinity ecosystem? +

Pair the Ionboard S44 with an inline fan, carbon filter and UIS controller so lighting, airflow and climate respond to each other automatically. For a deeper dive, check out our in-depth guide to AC Infinity systems.
