The DimLux 1000W DE EL UHF Expert Series is a complete high pressure sodium/metal halide fixture including the Alpha Optics reflector. This reflector is designed according to the Single Bounce Clear Sight (SBCS) principle and is equipped with Miro Silver mirrors. As a result the highest possible efficiency (98%) of all available horticulture reflectors is achieved. Provided with adjustable side reflectors for better overlap and to minimize wall losses. Due to the open design of the reflector the lamp is passively cooled which is a benefit for the life and efficiency of the lamp. There is a 50mm socket on the reflector which can be used to significantly reduce the room temperature by actively extracting the air. There are also optional add-on reflectors available which be placed to minimize the wall loss even more. This reflector is replaceable. Including Philips Master Green Power Plus 1000W DE HPS lamp (interchangeable with BLV Horturion DE Metal Halide lamp).
