The Gavita 315w CMH is perfect for tents up to 1m2 as standalone lighting or for use in-between two HPS fixtures as a supplemental light. If you want a Gavita CMH fixture to cover a larger space, take a look at the Gavita 630w CMH
The Gavita 315w CMH is compatible with the Gavita Master Controller this redefines the traditional installation of lighting fixtures, there’s no need for contactors and clocks as the controller takes care of everything. Use of the controller gives added safety features such as automatic dimming of your lights at elevated temperatures and even a safety shutdown.
The Gavita 315w is compatible with the Repeater Bus cabling system, allowing you to daisy-chain the fixtures in your installation. A Repeater Bus interconnect cable is included with every fixture. You can connect 5 strings of 100 fixtures per Master controller port. This enables you to control up to 1000 fixtures on one EL2 controller – perfect for industrial scale applications or for use alongside other Gavita fixtures in smaller spaces.
The fixture comprises of a ballast, reflector and lamp in one complete compact package. Made according to horticultural standards, the housing of the ballast is sealed and contains a gore-tex® plug to ventilate the housing, while keeping dust and humidity out. With no external lamp wires, there’s a low electromagnetic interference (EMI), making it compliant with FCC regulations.
Gavita mount the PCB and heat-generating components directly on the heat sinks instead of in a ballast bracket. The much cooler electronics result in a greater reliability, higher efficiency and a longer life. The innovative design of the fins across the housing increases the cooling effect thanks to the large surface area that allows for passive cooling.
The Gavita 315w CMH comes with a M140 SE CDM 315 reflector (Medium, 140 degree beam angle, for single CDM 315 Fixtures) – it’s much smaller than other options to fit the 315w lamp better and provide a more uniform spread of light. We recommend replacing reflectors yearly to keep your garden’s efficiency up – otherwise you may start to notice a drop in yield.
With your choice of Philips lamp included, the Gavita 315w CMH will help you bring your gardens quality up. We suggest using 942 4.2k (blue) lamps for vegetative growth and supplementary applications, while the 930 3k (red) lamp is best suited for floral development but can also be used throughout the entire life-cycle of the plant.
