40W Linear LED Grow Light Feature
Linear body, more even light
Design a 1200mm bar that can be slid into the canopy area or mounted flat on a vertical rack. The 120° beam works well at short distances, allowing the light to spread out nicely instead of creating a single, bright spot.
01
40W, but it's efficient
Input power is 40W. PPF is around 120 μmol/s, and efficacy can reach about 3.0 μmol/J. It's not a high-watt light. The point is saving power while you run more bars where coverage matters. Linking multiple units is common for this type.
02
Full spectrum + IR
White + blue + red + IR. White keeps growth looking "normal," blue helps structure, and red pushes photosynthesis. The IR is there for flowering/fruiting support, so it can follow the crop from the early stage to production.
03
0–10V dimming, group control
0–100% dimming, stepless. You can sync multiple lights together, so a whole bay or a rack section can be managed as one, especially when you want different outputs in different stages.

LED Grow Light Bar Key Benefits

More consistent growth, where it usually falls behind
By adding supplemental light, the middle and upper canopy get more active. Leaves and flower sites develop more evenly, and the plant works as a whole instead of fighting shade in different zones.

No extra heat stress
At 40W, with passive cooling, the light can be placed close to plants without pushing heat into the canopy. That makes it suitable for dense planting and multi-layer setups where temperature control matters.

Easy to scale as the system grows
The linear format keeps things simple. You can add lights row by row, or layer by layer, without tearing apart the whole setup. For many growers, this makes expansion much easier to plan.
Typical Applications
Be used in a wide range of industries

Inter-canopy supplemental lighting in greenhouses

High-density crops such as strawberries, tomatoes, and cucumbers

Vertical grow racks and multi-tier shelf systems

Supplemental lighting for leafy greens and nursery stages
In inter-canopy and vertical rack systems, this light is practical, stable, and well-suited for long-term operation.

Why Choose JT Grow Light (JTGL)
JT Grow Light focuses on commercial cultivation lighting. We don't just make fixtures. We work on spectrum design, structure, and system matching to help growers improve real production results.
Our LED Grow Lights range includes foldable, modular, linear, quantum board, and greenhouse lighting, with efficiencies from 2.8 to 3.4 μmol/J. Commercial projects across North America, Europe, and the Middle East utilize these systems.
Beyond lighting, we also supply vertical grow racks, rolling benches, and hydroponic systems. The idea is simple: help growers balance energy use, yield, and ROI in a way that makes sense for long-term operation.

FAQ
Q: Can this light be used for vertical farming racks?
A: Yes. The linear design and low heat output make it well-suited for vertical racks and multi-tier shelf systems, either as primary light for seedlings or as supplemental lighting for later stages.
Q: Does this light support dimming and group control?
A: Yes. It supports 0–10V dimming from 0–100%, and multiple lights can be synchronized for group control, which is useful for larger installations.
Q: Is it safe to use in humid greenhouse environments?
A: Yes. With an IP65 rating and passive cooling design, the light is suitable for humid indoor farms and greenhouse conditions with minimal maintenance.
Q: What crops are the lights commonly used for?
A: It's commonly used for strawberries, tomatoes, cucumbers, leafy greens, and nursery stages, especially in inter-canopy, rack, or supplemental lighting applications.
