Who This Is For
- You are adding targeted UV bars because your primary lights lack the spectrum needed to finish your crop effectively.
- You are automating UV timing because manually switching supplemental lights every day is easy to forget.
What We Found
- The magnetic mounting bars are a lifesaver when you need to reposition lights without wrestling with zip ties.
- We found the 365nm and 395nm wavelength mix provides a much broader UV response than single-diode bars.
What Users Say
- Users who added these bars in the final weeks say they noticed a visible increase in surface resin production.
- Growers running sealed rooms say the IP65 rating keeps the diodes safe from high humidity and foliage sprays.

FAQs
The main difference is coverage. The Ionbeam U2 includes two UV bars (24W total) for spaces up to 3'x3', while the more powerful AC Infinity Ionbeam U4 has four bars (48W total) for larger 5'x5' areas. Both models deliver the same targeted UV spectrum.
UV lighting is most effective during the final 2-3 weeks of the flowering stage. Use it for 2-4 hours per day to stimulate resin production. The Ionbeam's built-in timer makes it easy to schedule this exposure. Always start with lower intensity and shorter durations to acclimate your plants.
No, the Ionbeam U2 is a supplemental light. It provides specific UVA wavelengths to enhance flowering but lacks the full spectrum required for vegetative and overall growth. It should be used alongside a primary grow light like the AC Infinity Ionboard S24.
Installation is simple using the included magnetic bars. Attach the magnetic bars to your grow tent's steel frame, then snap the light bars into place. Position them 18-24 inches above your plant canopy for optimal coverage. For more tips on optimizing your setup, see our AC Infinity grow tent guide.
Yes, the Ionbeam U2 is part of the UIS platform and can be connected to smart controllers like the Controller 69 PRO. This allows for advanced programming and automation within the greater AC Infinity ecosystem.
