Cosmorrow LED 20W 24V 50 cm. InfraRed is a compact and waterproof bar designed to enhance flowering and ripening in indoor cultivation. It combines near infrared 730 nm with warm light 2100 K, providing radiant thermal support and controlled stem elongation at key moments.

The Cosmorrow LED 20W 24V 50 cm. InfraRed bar integrates a hybrid spectrum with 33% IR (730 nm) and 66% at 2100 K, designed to promote transitions to flowering, fruit bulking, and photochemical responses linked to far-red.
With a consumption of 20 W at 24 V (≈0.83 A), it offers a measured output of ≈38 μmol/s and efficiency of ≈1.9 μmol/J, ideal as a supplement to main spectrum LED grow lights.
The sealed, water-resistant body allows operation near irrigation or humidification, while the 50 cm format (470 × 32 × 14.5 mm, 0.16 kg) fits without taking up useful space under the canopy.
The IR radiation provides a light "heating" effect on tissues, improves thermal distribution between leaves, and promotes moderate elongation when it is convenient to open internodes.
It is mounted with the Cosmorrow ecosystem's fastening systems (clipped, screwed, or hung) and requires a specific 24 V power supply/wiring: Cosmorrow LED 1×20 W power cable for one bar or Cosmorrow LED 2×20 W power cable for two bars.
As part of the indoor electrical accessories, its role is strategic: fine-tune photomorphogenesis, improve temperature uniformity on cannabis plants, and maximize flower quality in cannabis cultivation.
In tents and rooms, a perimeter IR line reduces cold shadows, helps with surface drying after night watering, and stabilizes the microclimate near the top bud, maintaining exact light cycles with standard controllers.
In indoor cultivation, the combination 730 nm + 2100 K reinforces the far-red signal during flowering and ripening. The bar is integrated as auxiliary light on the sides or front of the tent to balance PPFD and provide gentle thermal comfort to the canopy, without increasing consumption or excessive heat.
It is used to accelerate flowering responses, promote bulking, and improve color/aroma in varieties sensitive to far-red. It also provides light radiant heat that helps on cool nights or areas with cold drafts, and allows controlled elongation when it is convenient to air out dense flower clusters.
Solution with excellent price-performance ratio: low consumption, specific spectrum for flowering, and quick installation within 24 V systems. Ideal to add value to main equipment without reconfiguring the entire lighting system.
Available at Hydroponics Blanes, trusted Grow Shop and a reference as Grow Shop in Spain, with discreet shipping 24/48 h. Wide catalog of LED grow lights, 24 V power supplies, and indoor electrical accessories to complete any project.
