The G8-240B Full Spectrum Bloom Only light by G8LED is formulated for the flowering phase of plant's growth cycle and provides flowering coverage for 2-4 blooming plants. This light replaces 300-400 Watts of a high-pressure sodium (HPS) bulb while only using 140Watts of power. This is a full spectrum flowering light and provides intense coverage for 6 square feet (3feet x 2feet) (0,6sq meter-91cm x 61cm) of grow space. This light penetrates 5feet (152cm) past the plant canopy and saves 50-60% on your electrical consumption. The electrical savings will pay for the light within the first year of usage.
