AC Infinity IONBEAM U4: 4-Bar UV LED Grow Light Kit (365nm & 395nm) – 11” Bars

Enhance your indoor grow with targeted UV

AC Infinity IONBEAM U4 adds four 11-inch UV LED bars to your existing lighting setup, delivering supplemental ultraviolet illumination that complements your primary grow lights. The bars are designed to sit flush with your tent or greenhouse frame, creating a seamless extension of your light spectrum and helping you tailor light exposure to your plants' rhythms.

By combining 365nm and 395nm UVA diodes, this kit nudges your cultivation mindfully toward the spectrum that plants respond to during key stages. While it won't replace your main lighting, the targeted UVA can be used to support flowering cues and fruiting development in a range of indoor environments, from small tents to larger greenhouses. The effect is a subtle, sun-like glow that can make colors in foliage and blooms more vivid and distinct, especially in twilight or dusk-like conditions.

Smart control for consistent cycles

The built-in digital controller provides ten intensity levels and daily schedule programming. This lets you dial in just-right light delivery, align with your plants' photoperiod, and maintain repeatable cycles without manual adjustments. A gentle ramp between steps can help reduce abrupt changes for sensitive crops while keeping coverage uniform across your grow area.

Mounting and flexibility

Designed for simple integration, the Ionbeam U4 can magnetically mount onto your grow tent frame or canvas using the included steel bars. This fast setup supports flexible spacing and easy repositioning as your grow space evolves or as you rotate crops during days of peak sun. The four 11-inch bars are ideal for supplementing corners or mid-line coverage within a tent, greenhouse, or grow room.
