Cosmorrow LED 40W 24V 90 cm. Ultraviolet is a LED grow light bar that adds controlled UV to the spectrum to enhance aroma, compactness, and natural defense in cannabis plants. 90 cm format, 40 W consumption, and 24 V power supply (driver not included), ideal for indoor cultivation.

The Cosmorrow LED 40W 24V 90 cm. Ultraviolet module integrates a near UV channel of 365 nm combined with cool white 6500 K, in an approximate ratio of 33% UV and 66% 6500 K.
This mix promotes photomorphogenic responses that can compact internodes, reinforce cuticles, and stimulate terpene synthesis, contributing to denser and more aromatic flowers. The sealed IP65 housing resists splashes, and the slim body (870 × 32 × 14.5 mm, 0.32 kg) makes it easy to mount on the ceiling or sides.
The rated current is 1.67 A and the operating range is maintained between 0–40 °C, with recommended storage at -20–60 °C.
A compatible 24 V power supply is required for operation (not included).
Options: COSMORROW Power Cable 1 × 40 W for one bar or COSMORROW Power Cable 2 × 40 W for two bars.
The connector is IEC 60130-10 OD5.5 ID2.1 L10. Installation can be screwed, clipped, or hung with the accessories that come with the driver.
In the Hydroponics Blanes ecosystem, a trusted Grow Shop and a benchmark as a Grow Shop in Spain, this UV bar stands out among electrical accessories for indoor for its versatility, low consumption, and ease of integration with main panels.
In indoor growing, the UV 365 nm channel of Cosmorrow helps reduce mold risks when used prudently, while promoting structural compactness and expressive aromatic profiles. The support of 6500 K sustains surface photosynthetic activity and evens out light distribution along 90 cm, optimal for plant rows, trays, or sides of the grow tent. The IP65 encapsulation allows operation in controlled humidity environments and facilitates cleaning and maintenance.
This bar works as supplementary lighting to add UV to fixtures that do not include it or to reinforce hybrid spectra. The linear format of 90 cm distributes irradiance evenly over the lateral or upper canopy. Key specifications include 40 W consumption, 24 V voltage, 1.67 A current, IP65 class, and long estimated lifespan. The lightweight design (0.32 kg) makes it easy to fix with clips, screws, or suspension. The IEC 24 V 60130-10 connector ensures a stable connection to the compatible driver, and the thermal operating range 0–40 °C fits well-ventilated and controlled rooms.
The 40 W format allows you to add UV to the system without renewing the entire lighting infrastructure. An option with a contained cost compared to complete panels, excellent for improving final quality and compactness in cannabis cultivation projects.
