Dimensions and Design

The G8LED 900 watt G8-900 is a 22-pound lightweight product that has 20.5″ x 14.0″ x 3.0″ dimensions to make it compact and ideal for regular apartments and houses. It also comes with a 6-foot power cord that is compatible with power supplies worldwide.

The G8LED G8-900’s design is unique since it doesn’t use a veg/flower switch.

The inclusion of a veg/flower switch usually involves turning off come of the red diodes during the vegetative phase and then turn them on for flowering.

That reduces the LED growing light’s energy efficiency and power utilization that results in fewer diodes being used to give energy to the plants.

The G8LED 900W averts this problem by using just one light for both these stages so you get maximum efficiency.
