The AC Infinity IONFRAME EVO4 is a 300 W bar-style LED sized to flower a 3x3 ft (90 x 90 cm) tent, or veg 4x4 ft. 896 diodes on a 52 x 58 cm frame — mostly Samsung LM301H EVO white in two colour temperatures, with Seoul UV, OSRAM deep red and OSRAM far-red mixed in. Ships with the Controller 77, so scheduling, sunrise and sunset ramping and ten brightness levels work out of the box. Genuine AC Infinity, stocked in Sydney and shipped domestically.
A bar fixture at 3x3, which is unusual
Most lights at this size are single panels, and a panel in a small tent gives you a bright patch in the middle and dim corners. The EVO4 spreads 896 diodes across a 52 x 58 cm frame instead, which fills a 90 cm tent far more evenly and lets you hang lower without scorching the centre.
In a small tent, headroom is usually the constraint. An even fixture you can run close to the canopy is worth more than a brighter one you have to hang high to make usable.
What is actually in the spectrum
The white base is Samsung LM301H EVO — 360 diodes at 3000K and 500 at 5000K, so this model is weighted cooler than its larger siblings, which suits its veg-through-flower role. AC Infinity rate the LM301H EVO at 3.14 µmol/J per diode. On top sit 4 x Seoul 395 nm UV, 28 x OSRAM 660 nm deep red and 4 x OSRAM 730 nm far-red.
Control, in the box and beyond it
The Controller 77 is included: daily schedule, sunrise and sunset ramping, ten brightness levels plus a power switch, and memory that restores settings after an outage. The light is also UIS compatible, so it can join your AC Infinity controller and run on one program with your extraction fan. Up to 80 lights can be daisy-chained — the splitter dongles this needs are sold separately, and each controller port carries up to 16 lights of the same series.
EVO4 or EVO3? Nearly the same wattage, different shape. The EVO4's 52 x 58 cm frame is squarer and built for a 3x3. The EVO3 is 41 x 83 cm — long and narrow, built for a 2x4. Buy the one that matches the shape of your tent, because a square fixture in a rectangular tent wastes light on the walls.

Questions we get asked
EVO3 or EVO4 — how do I choose?
By tent shape, not wattage. They are within 20 W of each other. The EVO4 is squarer (52 x 58 cm) for a 3x3; the EVO3 is long and narrow (41 x 83 cm) for a 2x4. Match the fixture to the footprint and the decision makes itself.
Will it do a 4x4?
For veg, yes. For flower, no — step up to the EVO6. Veg tolerates lower intensity across a wider area; flower does not, and stretching a 300 W light over 1.5 m² shows up in the corners.
Do I need a separate controller?
No. The Controller 77 is included and handles schedule, ramping and dimming. A UIS controller is an upgrade if you want the light on the same program as your fans.
What do I need to daisy-chain two of these?
A splitter dongle, sold separately — it is not in the box. Each controller port then carries up to 16 lights, all from the same series.
How much extraction does it need?
Size the fan to 300 W of input power rather than to the tent. A 100 mm or 150 mm inline fan with a carbon filter suits a 3x3 running this light, the larger one if the room is warm.
Is the 3.14 µmol/J figure for the whole fixture?
No. That is AC Infinity's efficacy figure for a single Samsung LM301H EVO diode, not the assembled light with driver losses included. We quote it as they publish it.
Is this genuine stock with an Australian warranty?
Yes. Quick Bloom Lights is the official Australian importer for AC Infinity. Stock is held in Sydney and warranty is handled here.
