A stellar lighting option for the vegetative phase, Sunmaster 250w Metal Halide (MH) Lamps imitate sunlight beautifully to stimulate rapid, regular growth capable of bearing heavy harvests. This lamp’s brilliant, 19,000 lumen blue-white light teases out sturdy branches, tightly packed internodes, and large leaves. All these attributes will put your plant at a massive advantage when the flowering phase comes around.

You can also deploy the Sunmaster Metal Halide as a supplementary light source during flowering. In this capacity it helps continue the healthy development it instigated during the vegetative phase, adds a touch of UV to enhance crop quality, and can aid oil production.

Manufactured to exacting standards, Sunmaster 250w MH lamps enjoy a long and constant life of around 7,500 hours. For ease of use the lamp fits any E40-fit fixture, meaning you can simply swap out the MH for a HPS lamp when flowering comes around.
