AC Infinity IONBEAM U4 11" UV Grow Light Bars, 4-Pack

The AC Infinity IONBEAM U4 is a four-bar supplemental UV lighting kit designed to add targeted ultraviolet light alongside a primary grow light. Each 11" bar uses 365nm and 395nm UVA diodes in a slim aluminum housing, providing a focused UV spectrum intended for fruiting and flowering stages.

The complete system draws 48W and includes four UV LED bars, a digital dimming and schedule controller, steel mounting bars, and mounting hardware. Each fixture is also IP65 rated for use in humid indoor grow environments.

• Kit: Four 11" UV LED Light Bars
• Spectrum: 365nm + 395nm UVA
• Power: 48W Targeted UV Output
• Controls: 10 Levels + Daily Schedule

Four 11" UV Light Bars

The IONBEAM U4 includes four 11" UV LED bars designed specifically for supplemental lighting.

Their compact profile makes them easy to position around a grow tent, along lighting fixtures with magnetic surfaces, or near areas where additional UVA exposure is desired.

Each bar measures approximately 10.98" x 1.08".

Targeted 365nm + 395nm UVA Spectrum

Unlike the full spectrum IONBEAM S-series bars, the U4 focuses exclusively on 365nm and 395nm ultraviolet wavelengths.

This targeted UVA spectrum is designed to supplement the primary grow light with wavelengths naturally present in sunlight.

The manufacturer positions the U4 specifically for use during fruit and flowering stages.

Supplemental UV Lighting

The U4 is intended to work alongside an existing primary grow light rather than replace it.

Its purpose is to add a targeted ultraviolet component to the overall lighting environment and expand the spectrum beyond standard white, red, and far-red horticultural lighting.

Fruit & Flower Stage Support

AC Infinity designed the U4 to provide supplemental UVA during later stages of plant development.

The 365nm and 395nm spectrum is intended to help draw out plant expressions during fruiting and flowering while complementing the output from the primary fixture.

Coverage for Common Grow Spaces

AC Infinity specifies different coverage depending on the number of bars used:

• 2 Bars: Full UV coverage for 2' x 2', 2' x 4', and 3' x 3' spaces.
• 4 Bars: Full UV coverage for 4' x 4' and 5' x 5' spaces.

This allows the supplied four-bar kit to be configured around a range of common indoor grow footprints.

Magnetic Grow Tent Mounting

The included steel bars allow the IONBEAM U4 fixtures to magnetically mount to grow tent frames, canvas, or compatible bar-style lighting fixtures with magnetic surfaces.

This gives growers flexibility to reposition the UV bars without permanently modifying the tent.

Digital Dimming Controller

The included controller offers 10 brightness intensity levels, allowing UV output to be adjusted to suit the application.

Available operating modes include OFF, ON, SCHEDULE, 10 brightness levels, and daily schedule programming.

Daily Schedule Programming

Built-in scheduling allows the U4 to run on a repeatable daily cycle without requiring a separate timer.

This is especially useful for supplemental UV applications where the light bars may be intended to operate on a different schedule than the primary grow light.

UIS Controller Compatibility

The IONBEAM U4 can connect to compatible AC Infinity UIS smart controllers.

Pairing the lights with a compatible controller provides access to expanded automation including climate triggers, grow cycles, schedules, and broader integration with other AC Infinity equipment.

App Control

When paired with a compatible WiFi-enabled UIS controller, the U4 can also be controlled through the AC Infinity app.

This can provide remote control, advanced automation, device scheduling, and integration with the rest of a connected UIS grow system.

IP65 Protection

Each UV bar is rated IP65.

This provides added resistance to dust and water exposure, making the fixtures suitable for humid grow tents and propagation environments.

Aluminum Unibody Construction

Each bar uses a unibody aluminum housing and board design.

The aluminum structure helps dissipate heat from the UV LEDs without relying on active cooling fans.

Propagation Compatibility

AC Infinity also lists the IONBEAM U4 as compatible with its humidity dome systems.

This allows the light bars to be used in propagation and seed-starting environments in addition to their primary role as supplemental UV lighting.

50,000 Hour Life Expectancy

The IONBEAM U4 carries a published 50,000-hour life expectancy.

Its LED-based design and passive aluminum cooling system support long-term operation without dedicated cooling fans.

Optional Smart Controllers

The IONBEAM U4 can be purchased with its included dimming and schedule controller alone, or bundled with a compatible AC Infinity UIS smart controller for expanded automation.

Controller 69 Pro — Independent programming UIS controller.

Controller 69 Pro+ — Independent programming UIS controller with 8-port connectivity for larger setups.

Controller AI+ — Environmental controller with AI powered learning and dynamic level adjusting.
