Inter-canopy LED grow light CULTI LIGHT CL-GL03-75 designed for optimal greenhouse plant growth.

CultiLight CanopyFlux™ Inter-Canopy LED Grow Light – CL-GL03 Series (75W / 150W)

Product Overview

The CultiLight CanopyFlux™ CL-GL03 Series is designed to deliver targeted illumination directly inside dense crop canopies. Unlike traditional overhead lighting systems, inter-canopy fixtures place light exactly where plants need it most — between rows and beneath upper foliage.

By improving light penetration within the plant structure, growers can increase photosynthetic efficiency, enhance crop uniformity, and support higher yields.

Engineered for commercial greenhouse and indoor farming environments, the CL-GL03 series provides reliable supplemental lighting for high-wire crops such as tomatoes, cucumbers, cannabis, and leafy greens.

With double-sided light distribution, high-efficiency LEDs, and rugged IP65 construction, the CanopyFlux™ system offers a durable and energy-efficient solution for modern horticulture lighting.

Light Coverage & PPFD Distribution

The CanopyFlux™ CL-GL03 Series is engineered to deliver uniform light distribution within dense plant canopies. The double-sided LED configuration spreads photons evenly across both sides of crop rows, improving light penetration to lower leaves and fruiting zones.

This targeted lighting approach increases photosynthetic efficiency where traditional top lighting often cannot reach.

Typical PPFD distribution depends on mounting height, crop spacing, and greenhouse configuration. The CL-GL03 series is commonly used as supplemental lighting for crops such as tomatoes, cucumbers, and cannabis.

Materials & Construction

The CL-GL03 fixture is built to withstand demanding horticulture environments.

Aluminum Housing

• Excellent thermal conductivity for efficient heat dissipation
• Natural corrosion resistance in greenhouse environments
• Lightweight yet durable structural design

Polycarbonate Optical Cover

• Over 90% visible light transmission
• High impact resistance
• Lightweight compared to glass optics

This combination ensures reliable long-term operation in indoor farms and commercial greenhouses.

Light Distribution

The CL-GL03 utilizes a double-sided 120° radiation angle, delivering wide light coverage across both sides of plant rows.

This design helps illuminate the interior of dense crop canopies, reducing shadow zones and improving light exposure for lower leaves and fruiting sites.

The result is more uniform plant development and improved crop productivity.
