Longer side lights for a wider growing area.
AC Infinity IONBEAM S16
Four full-spectrum light bars · 16-inch class
Buyer feedback ↓IONBEAM S16 extends the same modular idea as the S11: four independently positioned bars and a shared local controller. The longer bars need more mounting clearance but cover a longer run.

THE QUICK TAKE
Is it right for you?
Buy it when you need longer side-lighting runs with dimming and a daily schedule. Spreading the bars around a growing area can reach foliage that an overhead lamp misses.
Skip it when space beside the plants is tight. The S11 is shorter, and either system needs space for its cables and mounting hardware. A separate compatible UIS controller is required for remote app features.
01 / BUYING NOTES
Before you buy.
Set the local schedule first.
The supplied controller handles timing and ten intensity levels. More advanced remote triggers need a separate compatible UIS controller.

02 / AMAZON REVIEWS
The buyers’ view.
Owners describe easy installation, but magnetic mounting gets mixed reports: some use tent poles successfully, while others report sliding or bars that are easily knocked loose. Cable reach also varies by setup, with one owner finding it sufficient and another needing extensions.
Programming experiences differ too. One owner found setup and programming easy; another reported unexpected switch-ons with an AC Infinity controller and was unsure whether their configuration caused them.

The S16 uses longer bars than the S11, while retaining the modular mounting approach and local schedule controller. Smart remote integration remains a separate accessory decision.
