Supercharge Ionbeam U4 UV LED Grow Bars with smart controls for precision UV exposure and maximized plant growth.

Get to Know the AC Infinity IONBEAM U4 4-Bar Kit Targeted Spectrum UV LED Grow Light

Serious growers know that light quality matters just as much as intensity. The IONBEAM U4 is engineered to elevate your grow by adding targeted UVA wavelengths (365nm & 395nm), enhancing resin production, terpene profiles, and overall plant vigor. Built with a rugged, IP65-rated aluminum unibody, these bars handle humidity, heat, and dust without breaking a sweat. Whether you’re supplementing a high-powered LED or dialing in a seedling setup, the IONBEAM U4 fits seamlessly into any grow space with its easy magnetic mounting and UIS™-compatible smart controls.

Is the IONBEAM U4 Energy-Efficient?

Absolutely. Unlike outdated UV bulbs, the IONBEAM U4 operates at peak efficiency, delivering high-output UVA light with minimal energy waste. Traditional HPS setups struggle at 1.3–2.1 µmol/J, while modern LED grow lights hit 2.5–3.5+ µmol/J. These bars seamlessly enhance your primary lighting without excessive heat or power draw, making them a cost-effective solution for serious growers.

Features

  • Four 11” UV LED bars designed for supplemental ultraviolet lighting to assist primary grow lights.
  • Helps improve grow light quality to draw out plant expressions by simulating the sun’s UV rays.
  • Enhances fruit and flowering stages by utilizing a targeted UVA spectrum of 365nm and 395nm.
  • Features a digital controller with ten light intensity levels and daily schedule programming.
  • Can magnetically mount onto your grow tent's frame or canvas using the included steel bars.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
