## Description

Product Description A set of ultraviolet LED bars designed for use as supplemental lighting to improve light quality. When positioned ideally, these UV LED light bars will induce growth characteristics in your plants during fruit and flower growth stages. Its unibody housing and aluminum plate host a line of targeted spectrum ultraviolet LEDs while dissipating heat to extend its life. Each light bar features robust construction and IP65 rated to resist water and dust and can withstand wet weather. Also compatible with our moisture domes for use in germination and seed spread applications. This product is part of the UIS platform of smart cultivation devices and controllers designed to integrate each other to achieve your ideal environment. Uniform cover lighting Magnetically mounts to grow tent frames, bar style lamps with magnetic surfaces and screens when using the included steel bars. Provides even UVA coverage that complements your primary lighting to emit a spectrum of light naturally found in sunlight. Each LED light bar is constructed with 365nm and 395nm diodes that are formulated to extract expressions during fruit and flower development from your plant to improve the quality of your yields. Two bars will provide full UV coverage for 2x2, 2x4, and 3x3 spaces, while four bars fully cover the 4x4 and 5x5 growing spaces. Smarter Controls This kit includes an intuitive controller that features ten levels of brightness intensity with OFF, ON, and SCHEDULE modes. Lights can also be connected to our smart UIS controllers for integration with other growing equipment and access to dynamic climate triggers, cultivation cycles, and application control.

Review: Excelentes los productos de AC Infinity. Desde el empaque sientes la calidad. Muy buen apoyo de ventas también.
Review: Die AC Infinity IONBEAM U4 ist genau das, was ich gesucht habe, um zusätzliches, gezieltes Licht in mein Grow-Zelt zu bringen. Besonders in der Blütephase oder für schwer zugängliche Stellen wie seitliche Triebe ist dieses Lichtsystem ein echter Gamechanger. Die Lichtleistung ist trotz der kompakten Größe erstaunlich intensiv. Die U4 erzeugt ein schön ausgewogenes Spektrum, das perfekt mit meinen Haupt-LEDs harmoniert. Die Qualität ist – wie bei AC Infinity gewohnt – top: wertige Materialien, keine billigen Kabel oder Wackelkontakte, alles wirkt solide und langlebig. ✅ Vorteile: • Super für Side-Lighting oder als Ergänzung in kleinen Grows • Angenehm kühler Betrieb – keine Hitzeprobleme • Flexibel montierbar, leicht & kompakt • Steuerbar über das AC Infinity UIS-System – volle Kontrolle! ❌ Kleiner Hinweis: Wer große Flächen beleuchten will, sollte direkt mehrere Module nehmen oder auf die größeren Modelle setzen. Fazit: Klein aber oho! Perfekt für alle, die ihren Pflanzen gezielt Licht geben wollen – ich kaufe mir bald noch ein zweites Set!

The usual high quality you'd expect from ac infinity. I use this if I have to water because I had to work late and my main lights are off. I also use it if I have any reason to enter the room during the dark period. It has a timer so you can't accidentally leave it on and 4 brightness levels. I only use it on low. I trust ac infinity to provide the spectrum they advertise that does not disturb my plants when they are sleeping. I would highly recommend this over the screw in bulbs that do not mention the wavelength of green they produce. Very satisfied with this purchase.
