AC Infinity IONBEAM U4 UV LED Grow Light Bars. 4-Bar Kit, 48W

AC Infinity Targeted UVA LED Grow Light Bars for Late Bloom The IONBEAM U4 is a 48W four-bar UVA kit and supplemental UV LED bar set. It runs 365 nm and 395 nm diodes across 12 chips per 11-inch bar. Voltage input spans 100–240V. Each bar is IP65 rated with unibody aluminum housing. The kit ships with a 10-step digital dimming controller plus magnetic mount hardware. The four-bar layout covers 4×4 and 5×5 footprints. When and How Growers Run UVA in Late Flower UVA is supplemental, not primary. It runs alongside a white/red fixture, not in place of one. Growers typically run the fixture for 2–4 hours mid-photoperiod during late bloom. Ramp to 60–80% via the included controller for trichome and flavonoid response. The magnetic mount clips onto AC Infinity bar fixtures and most steel-frame tents in seconds. Connect into the UIS ecosystem for sensor-triggered scheduling. Key Features 365 nm + 395 nm UVA Diodes: Targeted UVA spectrum supplements primary lighting during fruit and flower stages without UVB exposure risk. 48W Total / Four 11-in Bars: Light enough load to run on a standard 120V outlet alongside the rest of a tent's gear. 10-Step Dimming Controller: OFF / ON / SCHEDULE modes with intensity ramping for late-flower windows. IP65 + Magnetic Mounts: Sealed unibody housing, magnetic clips for bar fixtures, and steel bars for canvas tent frames. UIS Platform Compatible: Connects into AC Infinity smart controllers for sensor-triggered or photoperiod-based scheduling.
