The Horticulture Lighting Market Growth trajectory is robust, with the market set to expand from USD 11.74 billion in 2026 to USD 30.52 billion by 2035, reflecting a strong CAGR of 11.2%. The primary catalysts for this growth include the expansion of cannabis legalization, with over 120 million square feet of permitted canopy in North America, driving demand for high-efficiency, spectrum-tunable LED arrays as the industry shifts from greenfield licensing to operational efficiency. The European Union's Fit-for-55 retrofit mandates are another significant driver, as the European Climate Law's legally obligatory 90% net emissions reduction target for 2040 forces greenhouse operators in the Netherlands and Spain to transition from optional programs to mandatory, extensive LED retrofits. Asian urban food-security policies, such as China's 14th Five-Year Plan earmarking CNY 80 billion for smart-agriculture infrastructure, are also fueling growth, with indoor-farming pilots receiving dedicated municipal subsidies.

From a regional perspective, growth dynamics are shifting across global markets. Europe remains the dominant region, accounting for roughly 31% of global revenue in 2025, underpinned by Dutch greenhouse innovation and Scandinavian vertical-farm investment. Asia-Pacific is the fastest-growing region with a projected CAGR of 14.4%, fueled by urban food-security mandates in Chinese and Japanese megacities, with Japan's plant-factory acreage growing 22% year-over-year in 2024. North America holds the second-largest share at approximately 28%, driven by cannabis cultivation infrastructure build-outs, with the United States accounting for 72% of regional share. South America and the Middle East & Africa represent smaller but strategically significant pockets of demand, driven by floriculture exports, protected-agriculture expansion, and sovereign food-security programs in arid climates.

The growth of the horticulture lighting market is further segmented by technology and cultivation, revealing specific areas of dynamism. LED systems commanded approximately 81% of the market in 2025, reinforcing their position as the default fixture across commercial grow operations, with Samsung and LG Innotek expanding mid-power LED chip capacity by an estimated 35% between 2023 and 2025. Retrofit installations are forecast to grow at a 14.4% CAGR as growers replace aging HID systems under energy-efficiency mandates, while vertical farms are the definitive growth story at a 16.3% CAGR, driven by urban food security and controlled-environment agriculture. By cultivation, tomatoes and peppers lead the market with a 22% share, while cannabis represents the fastest value-growth category in absolute dollar terms, driven by North American licensing and the shift toward operational efficiency and yield optimization.
