The AC Infinity Ionbeam S16 is a four-bar full-spectrum LED kit built on LM301H EVO diodes at 3.14 µmol/J. Each bar is 40.6 cm long and IP65-rated, and the included controller gives you ten dimming levels and a daily schedule. It sits over a Humidity Dome XL (6×12, 72 cells) for seedlings and cuttings, mounts magnetically to a tent frame as side or under-canopy lighting, and screws down as the main light in a small space, so it keeps working long after propagation. Quick Bloom Lights is the official Australian importer: stocked in Sydney, shipped domestically.
Complete lighting coverage
Four 40.6 cm bars spread light evenly across a tray instead of concentrating it in one hot spot, which is exactly what young plants want. The same bars do a second job later: the included steel strips let them mount magnetically to a tent frame or canvas, filling in the lower canopy and the edges your main light struggles to reach. Mounting screws are included too, so the kit can be the primary light in a propagation tent or small cabinet. Need more coverage? Add a second S16 set and the bars daisy-chain from a single controller.
LM301H EVO diodes are a step up from earlier LM301H and LM301B chips, with more light per diode and a stronger blue component that keeps seedlings compact. The 3000K and 5000K mix gives a full, balanced spectrum, and IP65 sealing means the bars are comfortable in the humid air of a dome or clone space.
Smarter controls
The controller has OFF, ON and SCHEDULE modes with ten brightness levels. That range is what makes the kit suited to propagation: start fresh cuttings and new seedlings low, then step the level up over a week or two as they harden off, rather than going from nothing to full power. Set the daily schedule once and the bars switch themselves on and off.
Pair it with the right dome
The S16 is sized for the Humidity Dome XL (6×12, 72 cells). For the 40-cell dome, the Ionbeam S11 (27.9 cm bars) is the matching kit. Add a Suncore seedling heat mat underneath and you have light, humidity and root-zone warmth covered. The full set is in our AC Infinity Propagation range.

FAQ
Is the S16 bright enough for seedlings and clones?
Yes, comfortably. Young plants need far less light than flowering plants, which is why the kit dims across ten levels. Most growers run it at the lower levels to start and raise it as the plants establish.
How high should the bars sit?
Over a humidity dome, the bars sit on or just above the lid. Out of a dome, start around 15–30 cm above the tops and adjust by eye: if seedlings stretch, lower the bars or raise the level; if leaves pale or curl at the edges, raise the bars or lower the level.
Can I use it as my main light?
In a small space, yes. Screw the bars to a shelf or the roof of a propagation tent or cabinet and they light it evenly. For a full-size grow tent the kit works best as supplemental side or under-canopy lighting alongside a primary light.
Can I link more than one S16 set together?
Yes, and it is one of the best things about the Ionbeam. The bars daisy-chain, so with two S16 sets you can run six or even all eight bars from one controller, and use the second controller for whatever is left over. That makes it easy to light a longer bench, two XL domes side by side, or a full row of tent side lighting from one schedule. Keep to one size per chain: S16 bars link with S16 bars, not with the S11 (27.9 cm).
Can I extend the cords between the bars?
The bars link with short connector cords. Longer leads are possible with a 12 V / 5.5 mm DC extension, but that is not a part AC Infinity supply or support, and we do not stock one.
S16 or S11?
Match the bar length to your tray. The S16 (40.6 cm) suits the Humidity Dome XL (6×12, 72 cells) and gives wider coverage as side lighting in a larger tent. The S11 (27.9 cm) is the matching kit for the 40-cell Humidity Dome.
Do I need an AC Infinity controller?
No. The included controller handles dimming and scheduling. A UIS controller is an optional upgrade for app control and running the light alongside your other UIS gear.
