Hortilux SchrÃ©der is the specialist in supplemental lighting systems for the horticultural industry. Hortilux has a complete range of reflectors and light fittings, experienced people and extensive research and production facilities. But most of all, they manufacture some of the most popular bulbs in our industry. The Hortilux HPS lamp was one of the first color-corrected bulbs specifically designed for growing plants to hit our industry. It has been the number one choice for many growers for many years now, and continues to be the number one selling bulb among growers. Their Hortilux Blue line of MH lamps is one of the most expensive lines of lamps around, but they are also the best metal halide lamps you can buy for maintaining plants in the vegetative stage.
