1. Philips: The Global Leader in Professional Horticulture Systems & Light Recipes

After more than 125 years of innovating in trustworthy lighting, Philips has combined this heritage with horticultural initiatives that involve revolutionary technology. Philips provides energy-saving LED grow lights in greenhouses, vertical farms, or research centers. A desire to embrace sustainability and precision agriculture translates into their interconnected lighting systems and their data-driven light recipes (such as the GreenPower series).

Philips is unique in its scientifically proven light recipes supported by hundreds of trials with researchers and growers. In contrast to competitors that only deal with hardware, Philips works in combination with spectral precision and crop-specific solutions in the fields of vegetable crops, fruits, and floriculture. Their GrowWise Control System can retroactively make dynamic lighting changes to their systems, making them among the very few competitors to attain. Fluence and Gavita may lead in cannabis, but Philips is the leader in large-scale greenhouse use cases with even light distribution and hybrid HPS-LED compatibility.

2. HLG: The USA-Assembled, High-Efficiency HPS Alternative

The American-born company, Horticulture Lighting Group (HLG), has changed indoor production with their Quantum Board technology. Proudly made in the USA their lights enable growers to save 60 percent on energy costs and increase yields. They offer lighting that works as well in basement tents as it does in commercial grows.

The 650R and 600Rspec fixtures by HLG are designed to substitute HPS 1:1 and consume 40 percent less energy—a claim few LED grow light manufacturers validate as effectively. Built in the USA to DLC-listed efficiency, HLG lights are eligible to utility rebates, which provide savings compared to other HLG manufacturers. In contrast to the research-oriented spectrum of Valoya, HLG brings more important focus on practical outcomes of cannabis growth, which commercial growers appreciate, such as Artsy Cannabis Co.
