SpectraB.2.G UV120 - 30W - UV-A LED Horticultural Bar 120cm Bloom

SpectraB.2.G UV120: the 120 cm UV-A LED bar that elevates your bloom

Engineered by BloomLED, the SpectraB.2.G UV120 is a 120 cm horticultural bar dedicated to UV-A radiation. Used alongside your main grow light, it intensifies the production of resins, trichomes and terpenes for denser, more aromatic and higher-quality flowers.

UV-A (a wavelength close to the visible range) triggers a natural defence mechanism in plants: they produce more secondary metabolites — resins, flavonoids and terpenes — to protect their flowers. Indoors, this controlled stress translates into a richer bloom and more pronounced aromas. With 30 W spread across 120 cm, the SpectraB.2.G UV120 delivers even radiation across your entire growing area.

UV-A radiation sits between 315 and 400 nm, just before visible light. Unlike the far more aggressive UV-B and UV-C, UV-A acts as a gentle, controlled stimulant. It penetrates the cuticle of leaves and flowers and activates the production of protective compounds without scorching the tissue. This is exactly the balance experienced growers look for: enough UV to trigger the plant's response, never enough to harm it. The SpectraB.2.G UV120 has been calibrated by BloomLED to deliver this ideal dose throughout the entire flowering phase.

IP65-rated and passively cooled, the bar runs without any fan: zero noise, zero maintenance and maximum lifespan, even in the humid atmosphere of a grow tent. Its slim bar format mounts in minutes above or alongside your canopy.

Why choose the SpectraB.2.G UV120?

For best results, run the SpectraB.2.G UV120 during the flowering phase, alongside your main lighting, for a few hours per day. You will quickly notice a more colourful, more compact and far more fragrant bloom.

Integrating the SpectraB.2.G UV120 into your setup

This UV-A bar is meant as a complement, never as a main light source. Pair it with a powerful full-spectrum horticultural lamp, such as the SpectraWILD M720 or SpectraBUD X60, which drives photosynthesis and the overall growth of your plants. The SpectraB.2.G UV120 then adds the finishing touch: the extra UV-A that makes the difference in the quality, aroma and density of the harvest.

For larger spaces or demanding crops, several bars can be combined to cover the entire canopy evenly. If you are new to UV, the SpectraB.2.G UV60 version offers a shorter format, ideal for smaller tents. In every case, BloomLED supports you with its expertise and a responsive, France-based after-sales service.

In short, the SpectraB.2.G UV120 is the ideal tool for growers who no longer want to settle for a decent bloom, but aim for aromatic excellence and maximum density. Rugged, waterproof, silent and backed by a 2-year warranty, it installs in minutes and works quietly at your side, season after season. Trust the BloomLED expertise, designed in France for over 10 years, to give your harvests the quality they deserve. Whether you run a single tent or a full grow room, adding targeted UV-A is one of the simplest, most cost-effective upgrades you can make to push your flowers further. Order your SpectraB.2.G UV120 today and feel the difference on your next harvest.
