The Sage NAU126BX-ROHS is an electronic ballast for CFL and linear fluorescents. The NAU126BX-ROHS has the leads coming out of the side. It is a program start ballast* and operates on 120-277Vac. It measures 6.50 x 1.90 x 1.14 inches. It will operate 1 or 2 18W, 1 or 2 13W or 1 26W CFL lamp. 1 or 2 18W or 1 or 2 13W Biax (TT5) compact fluorescents. 1 or 2 16W, 1 21W, 1 28W or 1 38W 2D lamps. Also 1 or 2 F14T5, 1 F21T5 or 1 F28T5 linear fluorescent lamps.
*A programmed start ballast for fluorescent and UV-C lamps extends lamp life by gently preheating the electrodes before ignition. This "programmed" preheat prevents electrode damage, making it ideal for applications with frequent on/off cycling, like offices with occupancy sensors. While it causes a slight delay in illumination and costs a bit more, its ability to significantly prolong lamp life makes it a cost-effective choice in the long run
