Modular LED bars for every stage and every gap in the canopy
Secret Jardin Cosmorrow LED Strips are low-profile, high-efficiency grow bars for propagation, veg, flowering and supplemental canopy lighting. Available in Full Spectrum, Grow, Bloom, UV and Infrared, they let you build a lighting setup tuned to each stage, and their IP65 build and low heat output suit tents, propagation racks and multi-tier hydroponic systems where fixtures sit close to the plants.
Key Benefits
- Up to 2.85 umol/J efficiency (model dependent) for strong output per watt
- Full Spectrum, Grow, Bloom, UV and Infrared options for a tailored spectrum
- Low heat output allows mounting close to the canopy without burn
- IP65 water-resistant for humid grow environments
- Modular 24V system that expands as your space grows
- 50,000-hour lifespan (L90B10) for long-term reliability
Cure stretch and starved lower growth
Patchy light and low intensity cause stretch, slow veg and thin, shaded lower buds. The Cosmorrow bars deliver even coverage and, thanks to their slim profile, drop in as side or under-canopy lighting to push light into lower growth and even out flowering.
How to Use
- Mount the strips with the supplied clips or Cosmorrow brackets.
- Connect to a compatible Secret Jardin Cosmorrow 24V power supply.
- Position at the recommended height for your chosen spectrum and stage.
- Use Grow or Full Spectrum through propagation and veg, Bloom in flower, adding UV or Infrared as supplemental lighting where appropriate.
- Keep good airflow around the canopy and wipe the covers periodically with a soft, damp cloth.
