PROGROW 1800 HL
High-output light. Minimal obstruction. Maximum growing potential.
High-Performance Linear LED Lighting for Greenhouse and Indoor Cultivation
Delivering 1,782 µmol/s of PPF, the PROGROW 1800 HL combines powerful photon output with a narrow linear design that minimizes obstruction of natural sunlight. Available in two purpose-built spectra with optional Bluetooth Mesh wireless dimming, it delivers exceptional efficiency, flexibility, and simplified installation for commercial greenhouse and indoor cultivation.
Powerful supplemental light. Designed to work with the sun.
In commercial greenhouse cultivation, the most effective lighting systems do more than simply provide additional light. They must complement natural sunlight while minimizing interference with the light already reaching the crop. The PROGROW 1800 HL is engineered for this environment. Its high-output, narrow linear design provides substantial photosynthetic light while minimizing the fixture's physical profile above the growing area. Unlike wider overhead lighting fixtures, the PROGROW 1800 HL's streamlined configuration is intended to reduce obstruction of incoming sunlight, helping growers make effective use of both natural and supplemental light. With approximately 1,800 µmol/s of PPF, the fixture delivers the photon output required for demanding commercial cultivation applications. The PROGROW 1800 HL is available with two spectrum options to accommodate different growing environments and lighting objectives. For greenhouse applications, the GLS Deep Red Dominant supplemental spectrum provides highly efficient photon delivery, achieving 3.3 µmol/J. For indoor cultivation, the GLS HI-RED full-cycle spectrum provides a broader spectral distribution designed to support plant development throughout vegetative growth and flowering. Optional Bluetooth Mesh wireless dimming provides an alternative to traditional wired lighting controls, simplifying installation by eliminating the need for dedicated dimming cables to each fixture. The result is a versatile, high-performance lighting platform that allows growers to select the spectrum and control configuration best suited to their operation.

Engineered Lighting Plans for Greenhouse and Indoor Cultivation
Every commercial cultivation environment presents unique lighting requirements.
In greenhouses, supplemental lighting must account for available natural sunlight, seasonal changes, crop requirements, greenhouse structure, and the grower's target daily light integral (DLI).
Indoor cultivation facilities present different challenges, including mounting height, canopy configuration, and target PPFD uniformity.
GLS uses professional lighting design software to evaluate each growing environment and develop lighting plans tailored to the facility's requirements.
Our engineering-driven approach helps determine:
- The appropriate spectrum for your cultivation environment.
- The optimal number and placement of fixtures.
- Appropriate mounting heights and fixture spacing.
- Projected supplemental PPFD and light uniformity.
- Lighting configurations suited to greenhouse structures and growing systems.
- The appropriate wired or wireless dimming configuration.
- The best combination of photon output, efficiency, and operational flexibility.
For greenhouse applications, the PROGROW 1800 HL provides an efficient supplemental lighting solution designed to complement natural sunlight.
For indoor cultivation, its HI-RED full-cycle configuration provides high-output lighting for demanding commercial cannabis production.
Rather than relying on generic fixture coverage recommendations, GLS designs lighting systems around actual facility dimensions, environmental conditions, and cultivation objectives.
