Hortimol LE90A10 UV+FR LED 90W LED Grow Light: lighting and specifications
This add-on module delivers a perfectly matched supplementary spectrum that conventional LED grow lights lack: UV-B for increased production of secondary plant compounds and far red (FR) for deeper flower development and the Emerson effect.
The two LED bars use OSRAM chips, are completely fanless, IP65 protected and UV and FR can be switched on separately. Thanks to adjustable brackets, the LE90A10 can be combined not only with the Hortimol MG series but also with Lumatek, Gavita, Fluence, Mars Hydro, SanLight and other brands.
With a total output of 90 W, it's the ideal addition to high-end indoor grows where aroma, essential oils, flower density and flower quality are the priority.
Why the Hortimol LE90A10 UV+FR?
Targeted UV-B (385 nm) for aroma, terpene & colour production
Increases secondary plant compounds, promotes natural defence mechanisms and enhances aroma profiles.
Far red 730 nm for strong flower formation
Improves light use (Emerson effect), helps balance stretch and supports flower formation.
Separate UV & FR activation
Full control: switch each on individually depending on the stage.
Universally compatible
Mounts on Hortimol MG6/MG8 and many other LED brands.
Ideal as supplementary lighting
Ideal for indoor areas from 100×100 to 120×120 cm.
Product description / product details
Effect & properties
UV-B activates the plant's own "sun protection system", boosting production of essential oils, terpenes and anthocyanins – ideal for more intense aromas and essential oil production.
Far red has a photomorphogenic effect: it improves light penetration, stimulates flower cluster formation and increases photosynthetic efficiency in combination with full-spectrum LEDs.
Thanks to light emission on both sides, you get an even spectral supplement without having to replace your main lighting. Minimal changes to your setup – maximum boost to final quality.
