Released to the market nearly three years ago, the Vanquish digital ballast line met with instant success. The unique attention to detail and no-compromise approach to manufacturing, have gained Vanquish digital ballasts a large following. Features like sequential lamp firing, soft lamp dimming, near-silent operation, splitter capabilities, and incredibly low levels of THD (Total Harmonic Distortion) allow the Vanquish line to run without fear of a knock on the door from neighbors or the cable company telling you that there seems to be a problem coming from your residence. The Digital line is all ETL/UL approved and is one of very few digital ballasts that passes the USA standards for FCC approval. Don’t be fooled by fake FCC markings that are often stamped on lower-end lighting units. Eliminate the worry and only settle for true USA FCC article, 18-part A&B standards. Vanquish is FCC certified for use in commercial and residential settings and assures years of rock solid performance.
