Custom Under Canopy LED Grow Lights in 1.8m & 2.4m — Built To Fit Your Grow Room, Not The Other Way Around

One of the most common problems commercial growers run into when sourcing under canopy lighting isn't the light itself - it's the size.

Standard grow light bars come in fixed lengths. But grow rooms don't. Racks vary. Row spacing varies. And when your light bar is 20cm too short or hangs awkwardly past the edge of your canopy, you're either wasting light or leaving gaps where your plants need coverage most.

That's exactly why we developed our custom under canopy LED grow lights in 1.8m and 2.4m - purpose-built lengths designed to match the way real commercial grows are actually set up.

 

What Is Under Canopy Lighting - and Why Does It Matter?

Your main grow light does a great job covering the top canopy. But everything below that - the lower bud sites, the inner branches, the secondary growth - gets a fraction of the light intensity that the top receives.

 

For cannabis growers, that means underdeveloped lower buds and uneven yields. For greenhouse and vertical farm operators, it means the lower tiers of your crop are always playing catch-up.

 

Under canopy LED grow lights are mounted between canopy layers, low and close to the plant, delivering direct light to the parts that need it most. The result is more even growth across the whole plant, better bud development from top to bottom, and - for commercial operations - a meaningful improvement in yield per square foot.

 

The key is getting the right light in the right size for your specific setup. That's where custom sizing makes all the difference.

 

Our Custom Under Canopy Grow Light Lineup

We currently offer our V20 series under canopy LED grow light bars in a range of sizes - including two exclusively customized lengths: 1.8m and 2.4m - designed to cover longer row runs without the need for multiple shorter bars daisy-chained together.

All models feature three-sided light emission - meaning light isn't just projected downward, but also reaches the sides of the plant for more complete canopy penetration.

Key Features Worth Knowing

1. IP65 Waterproof - Built for Humid Environments

Grow rooms are wet environments. Between irrigation, humidity control, and regular cleaning, your lighting takes a beating. Every unit in our V20 series carries an IP65 waterproof rating, meaning it's fully protected against dust and low-pressure water jets from any direction.

For commercial operations running automated irrigation or high-humidity environments, this isn't a nice-to-have - it's essential.

2. 0-10V Dimming - Full Control Across Growth Stages

Every model supports 0-10V dimming, giving growers precise control over light intensity at every stage of the crop cycle. Dial it down during early veg, ramp it up through flowering, or connect it to your grow room controller for automated light scheduling.

The V20 series also supports:

  • Three-in-one dimming for flexible control options
  • APP control via smartphone for remote adjustment
  • AC daisy-chain connection - up to 5 units per chain, significantly reducing wiring complexity in large installations

3. Three-Sided Light Emission

Unlike standard single-direction grow bars, our V20 series emits light from three sides - top, left, and right panels. This means even when mounted horizontally between canopy layers, light reaches the sides of branches and lower leaf surfaces, not just the tops.

For cannabis growers focused on lower bud development, this design feature directly translates to denser, more developed secondary buds.

4. Photon Efficiency: 2.9 μmol/J

With a light efficiency of 2.9 μmol/J, the V20 series delivers serious output relative to power consumption. For commercial growers running dozens or hundreds of bars, efficiency at this level adds up quickly in monthly energy costs.

 

 

Why Custom Sizing Matters for Commercial Grows

Most grow light manufacturers offer one or two fixed bar lengths and expect growers to work around them. We take a different approach.

Our 1.8m and 2.4m custom under canopy grow lights were developed in direct response to requests from commercial customers - greenhouse operators, cannabis facilities, and vertical farm setups - who needed longer runs without the hassle of joining multiple shorter bars.

The practical benefits of custom-length bars:

Cleaner installation - one bar per row instead of two or three shorter bars means fewer mounting points, less wiring, and a tidier overall setup.

More consistent light distribution - a single continuous bar delivers more even PPFD across the full length of the row compared to multiple bars with gaps between them.

Lower labor cost - fewer units to install, fewer connections to make, less time spent on setup.

Better aesthetics - for growers who care about how their facility looks (and many commercial operations do), a clean single-bar installation looks more professional than a patchwork of shorter lights.

 

Who This Is For

1. Commercial Cannabis Growers

If you're running a licensed indoor cannabis facility and you're not supplementing your lower canopy, you're leaving yield behind. Our IP65 waterproof under canopy grow lights are designed for the humidity levels, cleaning schedules, and continuous operation demands of commercial cannabis production.

2. Greenhouse and Vertical Farm Operators

For multi-tier growing systems, under canopy lighting is essential for ensuring the lower tiers receive adequate light intensity. Custom lengths mean you can match the bar to your tier depth without compromise.

3. Distributors and Wholesale Buyers

If you're sourcing under canopy grow lights wholesale for distribution across North America or Europe, our V20 series offers a strong product with a unique custom-sizing capability that gives your customers more flexibility than standard off-the-shelf options.

4. OEM and Private Label Brands

We offer full OEM and ODM services - custom branding, packaging, and spec adjustments available. If you're building a grow light brand and need a reliable under canopy grow light manufacturer behind you, let's talk.

 

 

Quality Control Before Every Shipment

Every unit goes through a professional aging test before it leaves our facility - running at full power for an extended period to verify lighting consistency, heat dissipation, and circuit stability under continuous operating conditions.

We check for:

  • Flickering or output inconsistency
  • Overheating or hot spots
  • Dimming response across the full 0-10V range
  • Physical and waterproofing integrity

Only units that pass ship. Every batch, every time.

 

Certifications

Our V20 series under canopy grow lights carry CE, ROHS, and FCC certifications - covering the key compliance requirements for sales in Europe, the UK, and North America.

 

For distributors and retailers selling into regulated markets, this matters. You need lighting that clears customs and meets retailer compliance requirements without extra paperwork on your end.
