The LUMii BLACK Blade 400w LED is a cool-running and efficient plate-format LED alternative to 600 W HID lamps. Giving full, balanced spectrum 3500K white light with added 660nm Osram chips, it is the ideal light source for the entire plant lifecycle. Its 2-plate, adjustable design allows the fixture to be used to light a 90 cm x 90 cm tent or a larger tent up to 1.2 m2, and the plates can be set to give the optimum light spread over the growing area. There is provision for mounting a LUMii Black Bar 30w UV/FR LED between the adjustable plates to provide additional UV and Far-Red light if required. Dimmable using integral control and can be scheduled using a plug-in timer. Powered directly by mains electricity via the 2 m power lead supplied. Complete with hanging slings for easy installation.
