Lumatek 30W UV Supplemental LED Bar – Unlock Your Plant’s Potential

The Lumatek 30W UV LED Bar lets you introduce controlled ultraviolet light into your grow space to boost resin production, pigment development, and aromatic intensity.

It’s designed to run alongside full-spectrum LEDs, and give your plants the additional wavelengths they’d naturally receive outdoors.

This fixture emits a targeted blend of UV-A (365–400nm) and UV-B (280–315nm) light, which stimulates the production of secondary metabolites like terpenes, flavonoids, and trichomes.

Used sparingly in the final bloom phase, it helps bring out richer flavours, deeper colours, and frostier flowers. We've trialled this bar in-house and recommend using it for 2–4 hours per day during the last 2–3 weeks of flower.
