AC Infinity Ionboard – The Light That Doesn't Ask for Attention
There's a strange habit in grow lighting of judging a light by how impressive it looks switched off. Big frames, lots of bars, a spec sheet that reads like a car brochure. Plants don't care about any of that. They care about three dull things: how much useful light lands on the leaf, how evenly it lands, and whether it keeps doing that every day for years without fuss.
The AC Infinity Ionboard is built around those three dull things. It's a single slim aluminium board covered in Samsung LM301H full-spectrum diodes, laid out so the edges of your tent get light too, not just the middle. No fans to fail, no hum, no fuss. You hang it, plug it in, and get on with your life.
Which Ionboard?
Pick the board that matches the footprint of your tent or shelf. That's the whole decision.
| Model | Power | Best footprint | Good for |
|---|---|---|---|
| Ionboard S22 | 115W | 60 × 60cm (2×2ft) | Small tents, propagation, houseplant shelves, seedlings |
| Ionboard S24 | 200W | 60 × 120cm (2×4ft) | Long, narrow tents and shelving runs |
| Ionboard S33 | 240W | 90 × 90cm (3×3ft) | The all-rounder for mid-size tents |
| Ionboard S44 | 400W | 120 × 120cm (4×4ft) | Full-size tents and serious canopies |

Why it works
- Samsung LM301H diodes: among the most efficient white LEDs made, so more of what you pay the electricity company for ends up as light rather than heat.
- Even coverage: the diode layout is spread to reduce the bright centre and dim corners that cheaper boards suffer from.
- Silent, passive cooling: a solid aluminium body pulls heat away with no fan, which means nothing to whine at 2am and nothing to wear out.
- Built-in dimming: turn it down for seedlings and cuttings, up for fruiting and flowering.
- UIS smart control: plug it into an AC Infinity Controller 69 Pro, 69 Pro+ or Controller AI+ for schedules, sunrise and sunset ramps, and app control alongside your fans and humidifiers.
Not just for growers
A good LED is simply indoor sunshine you can control. Ionboards are just as happy over a shelf of aroids, calatheas and begonias, a winter tray of chillies and tomato seedlings, a herb garden in a dark kitchen, or a cactus and succulent collection that's stretching towards the window. If your plants are leaning, they're telling you they want one of these.
🌿 Rose's Pro-Tip: start new plants and cuttings with the board dimmed and hung higher, then bring it down and turn it up over a couple of weeks. Plants adapt to strong light the same way we adapt to sun, gradually, and the result is stockier growth rather than bleached leaves.
