Cosmorrow LED Power Cable 2x20 W powers two COSMORROW® LED 20 W bars with a single robust and tidy kit for indoor growing. Includes transformer, cables and fastenings, ideal for shelving, propagators and side reinforcement with LED grow lights.

The Cosmorrow LED 2x20 W Power Cable brings together everything you need to power two 20 W bars with a total consumption of 40 W, offering a clean and stable setup.
The set operates between 100–220 V and 50/60 Hz, includes IP54 protection against dust and splashes, and maintains reliable operation within thermal ranges of 0–40 °C (operation) and −20–60 °C (storage).
The assembled block has compact dimensions of 470 × 12 × 40 mm, spacing between bars of 9 cm and an approximate weight of 0.80 kg, perfect measurements to cover cutting trays, vegetative shelves and mesh sidewalls.
The pack includes a 24 V DC cable of 180 cm and a mains cable of 60 cm, with C (EU), G (UK) and A (US) plugs for international compatibility.
The DC 5.5 × 2.1 × 10 mm connector ensures a firm connection with each bar; the supplied fasteners make it easy to install on light structures or metal profiles without complex tools.
This kit multiplies light uniformity in critical zones: propagation, mother plant maintenance, technical corridors and cabinet perimeters with central HPS, LEC/CMH or LED panels.
Two well‑powered bars eliminate shadows, improve side coverage and help stabilize photoperiods without adding significant heat to the canopy.
As part of indoor electrical accessories, the standardized format reduces failure points, simplifies replacements and shortens downtime. In circuits with timers and controllers, tidy cabling means fewer interferences and consistent start‑ups.
For cannabis growing with demanding cannabis plants, this stability translates into compact growth, active leaves and more predictable transitions to flowering.
The kit’s design encourages placing the transformer outside wet areas, routing cables along the perimeter with ties and keeping free airflow around filters and extractors. Everything is designed for rooms and tents that seek sustained productivity with contained power consumption.
In indoor growing, two LED lines controlled by a single Cosmorrow LED 2x20 W Power Cable achieve even coverage on trays, shelves and canopy edges. Fixed spacing of 9 cm optimizes photon distribution and minimizes dead zones at working levels and along the sides of the tent.
It is used to power two 20 W COSMORROW® LED bars with a single source, reducing cables, gaining order and improving uniformity. Direct application in propagators, light vegetative phases, perimeter support and preparation areas, combining low consumption and high versatility alongside main LED grow lights.
Solution with an excellent price-utility ratio to expand critical areas without increasing complexity. A contained investment that improves order, electrical safety and operational continuity on shelves, propagators and canopy perimeters.
