Choosing the right Secret Jardin TLED or Cosmorrow LED bar

Lower branches not getting enough light from your overhead panel? TLED and Cosmorrow LED bars deliver targeted supplemental illumination exactly where it matters. Mount them vertically along tent poles or horizontally above propagation trays — the minimal heat output allows placement as close as 5-15 cm from the canopy.

The TLED 23W suits small tents and propagators, the 42W covers wider spaces, and the TNOLED 2×40W handles full vegetative lighting. Cosmorrow 40W bars offer next-generation efficiency (PPE up to 2.85 µmol/J) with IP65 protection. Fast delivery across Belgium.

Our Secret Jardin TLED and Cosmorrow range

Supplemental lighting is often the missing piece in an otherwise well-equipped grow setup. The Secret Jardin TLED and Cosmorrow LED bars are purpose-built for exactly this role: targeted illumination for propagation, side lighting and compact grow spaces where a full LED panel would be impractical or excessive. Designed to integrate seamlessly with Secret Jardin grow tents, these bars bring light precisely where your plants need it most — stocked in full at Plant & Flower.

Targeted light for every grow scenario

The TLED range from Secret Jardin addresses a specific challenge that many indoor growers face — the lower and side branches that never receive enough direct light from overhead panels. By mounting these slim LED bars vertically along tent poles or horizontally above propagation trays, you deliver photons exactly where they are needed most. The minimal heat output means you can position them as close as 5 to 15 cm from the canopy, turning previously underperforming areas of your grow space into productive zones that contribute meaningfully to your overall yield.

Classic TLED, Cosmorrow or TNOLED — which one?

The TLED 23W Bloom is perfectly sized for small tents measuring 40 to 60 cm wide, propagation domes and compact clone setups. Its low power draw makes it particularly economical for propagation areas that run continuously for weeks or months at a time. The TLED 42W Bloom delivers noticeably greater light output and suits tents in the 60 to 80 cm range or functions as effective side lighting. Both models mount horizontally or vertically using the included clips, giving you complete flexibility in positioning.

For more demanding installations, the Cosmorrow 40W Grow represents the evolution of the TLED: an ultra-thin 70 cm form factor (16 mm), IP65 waterproof, with improved efficiency of 2.7 to 2.85 µmol/J depending on spectrum. The TNOLED 2×40W Grow mounts two bars on a single frame covering up to 120×40 cm. The Cosmorrow 40W power supply is sold separately — essential for Cosmorrow bars which run on low-voltage 24V.

FAQ - Frequently asked questions about Secret Jardin TLED

Which TLED is best for clones and seedlings?

For clones and seedlings, choose a vegetative spectrum model. The TLED 23W works well for propagation domes and small clone setups up to 60 cm wide. If you need more output for a larger propagation area, the Cosmorrow 40W Grow offers improved efficiency in a similarly compact format.

Can a TLED bar replace a main LED grow panel?

In small tents of 40 to 60 cm, a TLED 42W or Cosmorrow 40W can serve as the primary light source effectively. For larger grow areas, TLED bars are designed as supplemental lighting — mounted alongside a central LED panel to eliminate shadow zones and improve light penetration into lower canopy layers where buds would otherwise underdevelop.

What is the difference between TLED and Cosmorrow?

The Cosmorrow is the next evolution of the classic TLED: higher efficiency (PPE up to 2.85 µmol/J), ultra-thin 16 mm form factor, IP65 protection and better-balanced full-spectrum output. The classic TLED remains available as a cost-effective option for propagation and small-scale setups. Note: the Cosmorrow requires a dedicated 24V power supply sold separately.

How close can I place a TLED bar to my plants?

The recommended distance is 5 to 15 cm. Keep 10-15 cm for clones and young plants as they are more sensitive to light intensity. You can move closer to 5-10 cm during active vegetative growth and flowering thanks to the minimal heat output. Monitor your plants for the first few days after any adjustment to ensure they respond well.
