Part of the professional line of Gavita lighting fixtures, The Gavita Slim Line series is designed especially for grow rooms. These professional lighting fixtures suit flexible and fixed installations and are compact with a Repeater Bus interface (no manual control). For 208V three-phase or 240V, the reduced height makes this the lighting fixture of choice for low rooms. With a slim-line ballast and only 9.7 inches (19,4 cm) high, the highly efficient passive cooling of this lighting ballast translates into longer electronics lifetime. The housings are sealed with Gore-Tex ventilation plugs.
