Since 2005, Illumitex has led the horticulture lighting industry with a perfect balance of horticulture scientific know-how and innovative design. Just like the careful balance each of our growers take in developing the perfect recipe, Illumitex scientists and engineers work closely together to find the right solution for a variety of growing environments. We have a passion for horticulture lighting and will continue to lead the development of products that will influence plant benefits including yield, taste, color and smell.Lighting, very often, is the single most expensive and critical part of a successful Controlled Agriculture Environment (CEA). It is our goal to understand this symbiotic relationship between light, air, water, and soil with each customer we serve. Our specialized team will work with growers to assist in creating that optimal result and to make sure we provide top-tier service.



At Illumitex, we design LED lighting systems and digital horticulture solutions for CEA operations. Based on scientific research on PPF, PPFD, PAR, spectra, lumens, and heat, we are able to innovate best-of-breed technologies for our consumers. Our product line conserves energy spending through cutting-edge technology. Our team consists of horticultural professionals including: design experts, engineers, experienced growers, and plant scientists all working directly with customers to deliver world class horticulture solutions.
