PROGROW 4800 HB
Sunlight-level intensity.Exceptional uniformity. Extraordinary potential.
Ultra-High-Intensity LED Lighting for Commercial Cultivation
Delivering 4,842 µmol/s of PPF, the PROGROW 4800 HB is engineered to achieve canopy intensities exceeding 2,000 PPFD in properly designed 5′ × 5′ lighting arrays. Its powerful high-bay design supports advanced cannabis cultivation and high-intensity applications such as algae production in photobioreactors.
Push the limits of light. Explore the potential of your crop.
Light is one of the most important drivers of photosynthesis and plant productivity. For commercial cannabis cultivators, increasing light intensity can create opportunities to improve yields when other essential growing conditions are properly managed. While many commercial cultivation facilities target canopy intensities around 1,000–1,500 µmol/m²/s PPFD, some growers are exploring significantly higher intensities to unlock additional production potential. The PROGROW 4800 HB is engineered for these demanding applications. With 4,842 µmol/s of PPF — approximately twice the output of the PROGROW 2400 HB — it provides the photon delivery needed to support exceptionally high canopy intensities. When installed in a properly designed 5′ × 5′ fixture array, the PROGROW 4800 HB is capable of delivering light intensities comparable to direct midday sunlight, exceeding 2,000 µmol/m²/s PPFD. Its high-bay configuration allows fixtures to be positioned approximately four to five feet or more above the plant canopy, promoting effective light distribution and overlap between adjacent fixtures. Beyond conventional crop cultivation, the PROGROW 4800 HB has also been successfully used for algae cultivation in photobioreactor systems, where its exceptionally high photon output can support demanding photosynthetic lighting requirements. The result is an exceptionally powerful lighting platform that gives commercial growers and other photosynthetic production operations greater flexibility to explore advanced cultivation strategies.

Custom Lighting Plans for High-Performance Cultivation
Achieving exceptionally high PPFD levels requires more than powerful fixtures. It requires careful engineering to ensure that light is distributed effectively and consistently across the entire cultivation area.
GLS uses professional lighting design software to evaluate each facility and develop lighting plans tailored to the grower's room dimensions, mounting heights, canopy configuration, and intensity objectives.
The PROGROW 4800 HB provides an exceptionally powerful solution for commercial cultivators seeking canopy PPFD levels of 2,000 µmol/m²/s or more.
Its high photon output also makes it a compelling option for algae cultivation in photobioreactors, where lighting requirements depend on reactor geometry, light penetration, and the specific photosynthetic characteristics of the organism being cultivated.
Our engineering-driven approach helps determine:
- Which PROGROW model best fits your cultivation objectives.
- The optimal number and placement of fixtures.
- Appropriate mounting heights and fixture spacing.
- Projected canopy PPFD and light uniformity.
- Lighting configurations that support both conventional and ultra-high-intensity cultivation strategies.
- Application-specific lighting arrangements for photobioreactor systems and other specialized photosynthetic production environments.
