Targeted UVA bars boost resin, terpene and fruit development with magnet‑mount bars and smart scheduling.

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 Unlike outdated UV bulbs, the IONBEAM U4 operates at peak efficiency, delivering high-output UVA light with minimal energy waste.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.
