The AC Infinity IONBOARD S44 is a 430 W full spectrum LED grow light for a 122 × 122 cm (4 × 4 ft) tent: 1,024 Samsung LM301H diodes plus 660 nm red and 730 nm far-red on a 60 × 60 cm aluminium board, running at 2.75 µmol/J. It dims from 0–100% on the driver and plugs into AC Infinity UIS controllers for scheduling, sunrise/sunset and app control. This stock ships with a US plug, which is why it is on clearance. Genuine AC Infinity, stocked in Sydney and shipped domestically.
Optimised spectrum
The board carries Samsung LM301H diodes in 3000 K and 6500 K white, with 660 nm red for flowering and 730 nm far-red. AC Infinity position the diodes algorithmically across the board for an even PAR map and deep canopy penetration, so plants at the edge of the tent get closer to what the centre gets. Peak output is rated at 2,034 µmol/m²/s PPFD, and it runs from seedling to flower: dim it down early, bring it up as the canopy fills.
Future ready controls
The IB-400 driver has a knob for 0–100% brightness in 20% steps and a UIS port. Connect it to an AC Infinity UIS controller, such as the Controller 69 Pro or Controller AI+, and the light runs on a schedule with sunrise and sunset ramps, can dim automatically when the tent overheats, and can be managed from the app over WiFi. The port also daisy-chains additional lights. The controller is sold separately.
Built for the tent
The unibody aluminium board spreads heat across its full area, and the fixture is sealed to IP65 for the heat and humidity of a flowering tent. It is rated to run from 0 to 60 °C and 35–85% RH, with a 50,000-hour diode life expectancy. Metal bar hangers and rope hangers are in the box. The fixture is 60 × 60 cm and 1.1 cm thick, so it hangs low in a tent without eating height.

FAQ
Will it work on Australian power?
Yes. The driver accepts 100–277 V at 50/60 Hz, which covers Australian 230–240 V mains. Only the plug differs: use a certified plug adapter or have an electrician fit an Australian plug.
What size tent does it suit?
A 122 × 122 cm (4 × 4 ft) tent. The 60 × 60 cm board and even diode layout are designed to spread light to the corners of that footprint.
Do I need a controller?
No. The driver knob dims it 0–100% and you can run it from a standard timer. A UIS controller adds schedules, sunrise/sunset, temperature-based dimming and app control.
How high should I hang it?
Start higher and at lower brightness for seedlings and young plants, then lower it and raise the dimmer as the canopy fills. Watch the top leaves: bleaching or curling up means too much light for that height.
