AC Infinity’s Ionboard and Ionframe are two LED grow light lines built for home tents. The Ionboard is a compact quantum board style light for 2×2 to 4×4 spaces, and the Ionframe EVO is a bar style fixture that scales from 2×4 tents up to 6×6 rooms. Both are designed to plug into AC Infinity controllers, so you can schedule and dim the light alongside your fans from one unit or app. On paper, they suit cannabis growers who already use AC Infinity gear and want lights that fit into the same system. Pair them with strong genetics from our indoor seeds. This guide is for adults 21 and older growing where home cultivation is legal.

This is a spec based review. It draws on AC Infinity’s published product pages and manuals plus common grower feedback. We did not run our own test grow, and Kind Seed Co is not affiliated with AC Infinity. Always check current specs, as models and diodes can change between versions.

AC Infinity Ionboard

The Ionboard is a flat board covered in diodes. AC Infinity lists several sizes:

Model	Listed power	Listed coverage	Notes from the maker
S22	115 W	2×2	Listed efficiency 2.7 umol/J
S24	Check maker	2×4	Rectangular board
S33	260 W	3×3	Mid size tents
S44	430 W	4×4	Listed efficiency 2.75 umol/J

AC Infinity lists Samsung LM301H diodes for the current boards, though an older manual mentions LM301B, so diode type may vary by version. The maker also lists an IP65 rating for moisture resistance, a dimmer and a fanless design. For small tents, a board is simple to hang and easy to dial in.

Ionboard strengths

• Compact and simple. One board, a few hangers, done.
• Sizes for common tents. Easy to match to a 2×2, 3×3 or 4×4.
• Controller ready. Links to AC Infinity controllers for schedules and dimming.
• Moisture resistance. The listed IP65 rating helps in humid tents.

Ionboard trade offs

• More concentrated light. Boards put diodes in a smaller area, so the center can be brighter than the edges.
• Heat in one spot. Without fans, the board relies on its heat sink.

AC Infinity Ionframe EVO

The Ionframe EVO is a bar style fixture with diodes spread across several bars. AC Infinity lists flowering coverage by model:

Model	Listed flower coverage
EVO3	2×4
EVO4	3×3
EVO6	4×4
EVO8	5×5
EVO10	6×6

The maker lists Samsung LM301H EVO diodes and a detachable driver, which lets you mount the driver outside the tent to keep heat out. AC Infinity’s efficiency figure for this line refers to the diode rather than the whole fixture, so we do not quote a fixture efficiency here. Check the spec sheet for whole fixture numbers.

Ionframe strengths

• Even coverage. Bars spread light across the canopy. Read quantum board vs bar LED.
• Scales up. Sizes from small tents to 6×6 rooms.
• Driver outside the tent. Less heat where your plants are.
• Controller ready. Same UIS link as the Ionboard.

Ionframe trade offs

• Larger and heavier. Needs a sturdy tent frame.
• Bar spacing matters. See grow light bar spacing.

The controller advantage

The main reason to pick an AC Infinity light is integration. If you already run an AC Infinity controller for fans, the light can share schedules and settings, and some controllers can dim lights in response to heat. That can keep your tent steadier without extra timers. Read environmental controllers for grow rooms and smart grow light controllers.

If you do not use AC Infinity controllers, the lights still work with their own dimmers and a simple grow light timer.

Which one should you choose?

Your setup	Better fit	Why
2×2 tent, first grow	Ionboard S22	Simple, compact
3×3 tent	Ionboard S33 or Ionframe EVO4	Board for simplicity, bars for spread
4×4 tent	Ionboard S44 or Ionframe EVO6	Bars usually give more even edges
5×5 or 6×6 space	Ionframe EVO8 or EVO10	Only the bar line covers these sizes
Already own AC Infinity controller	Either	Both link through UIS

Setting up for cannabis

1. Hang high for seedlings and dim low. Young plants need gentle light. See cannabis seedling light schedule.
2. Raise intensity in veg. Lower the light or dim up as plants grow.
3. Push in flower with care. Read when to increase light intensity in flowering.
4. Check distance. Follow the maker’s guide and our LED light distance for cannabis.
5. Map your light. A quick PPFD map shows hot and dim spots.
6. Watch for bleaching. Pale tops near the light mean back off. See light bleaching cannabis.

Heat, power and running costs

Fanless LED fixtures stay quiet, but they still turn some power into heat. A bigger fixture in a small tent will warm the space quickly, especially in summer. Mounting the Ionframe driver outside the tent helps, and a correctly sized exhaust fan does the rest. Read grow light heat management for practical tips.

Running cost depends on wattage, hours per day and your power rate. A flowering cycle with 12 hours of light per day costs less per day than a long veg run with 18 hours. Our guide to grow light electricity cost walks through the math so you can compare models before you buy.

Spectrum and build

Both lines use a full spectrum white light, which looks close to natural light and makes it easier to spot problems on leaves. White light also makes photos look true to color, which helps if you track your grows. Check the spec sheet for any added red or other diodes on the model you choose, since spectrum details vary between versions.

On build, both lines are fanless, so the only moving parts in your tent are your fans. That keeps noise down and removes a common failure point. Check that the hanging hardware, cables and driver mounts fit your tent before you buy, especially with larger Ionframe models.

Quick buying checklist

• Measure your tent, including the height left after pots and plants.
• Match the listed flowering coverage to your tent, not just the wattage.
• Decide whether you want controller integration now or later.
• Confirm the current diode type and warranty on the maker’s page.
• Plan exhaust to handle the extra heat in summer.

How these compare with other home lights

Board and bar fixtures from many brands now use similar diode types. What separates them is the full fixture design: driver quality, heat sink, diode count, spread and warranty. AC Infinity’s main extra is the controller ecosystem. If that matters to you, these lights are an easy fit. If it does not, compare listed coverage, efficiency and warranty with other fixtures in the same size class, and read grow light diode binning to understand why diode names alone do not tell the full story.

Frequently asked questions

Is the AC Infinity Ionboard good for cannabis?

On paper, yes, for small to mid size tents. It lists full spectrum output, dimming and controller support.

What is the difference between Ionboard and Ionframe?

The Ionboard is a compact board. The Ionframe EVO is a bar fixture that spreads light more widely and comes in larger sizes.

Do I need an AC Infinity controller to use these lights?

No. Both have their own dimming. A controller adds scheduling and integration with your fans.

Which Ionframe size fits a 4×4 tent?

AC Infinity lists the EVO6 for 4×4 flowering coverage.

Are Ionboard and Ionframe lights waterproof?

The maker lists moisture resistance ratings, such as IP65 on the Ionboard. That helps in humid tents, but you should still keep water off the fixture and driver.
