With the New Nanolux DE Dual fixture (600Wx2), we have split our 1200W DE into two 600W lamp outputs. This allows the fixture to run both a 2K DE HPS lamp and our brand new double jacketed 6K MH DE lamp, or the optional 4K MH DE lamp (sold separately). This dual lamp combination provides a spectrum that is unmatched by any other existing HID technology currently on the market. The spectral output of the 6K DE MH lamp combination with the 2K DE HPS lamp provides additional blue light that benefits your plant. DE Dual 600_d This fixture provides a very comprehensive PAR spectrum while pumping out 1200W of the most powerful light. Use any combination of DE lamps to create the spectrum the plants desire! This fixture is commercial grade in its design quality and durability. The Nanolux DE Dual Fixture (600Wx2) is NCCS ready. NCCS (Nanolux Cloud Control System) is one of the many technologically advanced features offered exclusively by Nanolux. With NCCS, you will be able to control up to 999 lights on your computer. Like all Nanolux ballasts, the DE Dual Fixture comes with random start technology. Random start uses an algorithm that will start the ballast within a 0-15 second window. This allows for less initial power draw when using multiple ballasts. Layout of the lamps must be the same for each fixture For example, HPS lamp in left socket and MH lamp in right socket. This is to be the same for all fixtures running. This ensures proper mixing of spectral output to make an even overlapping light pattern in commercial applications.
