With strong PAR output and a wide spectrum, the Lightspeed PRO series 1000W Double Ended Metal Halide bulb was created for maximum vegetative growth. An emphasis on the blue spectrum provides for tight internodes and minimal stretching. A strong red/orange peak compliments the blue and powers chlorophyll absorption which drives the synthesis of compounds used for energy and building materials within plant cells.
