The vPRO 2 Transformers are low profile, light weight, stainless steel and utilize solid-state technology. A proprietary, downloadable app allows the transformer to be controlled by any Bluetooth® enabled device. Multi-stage dimming of all loads is quickly accomplished, regardless of light source. Dimming is smooth: from full bright to off. Functionality is further enhanced with adjustable astronomic timing, dual-zone output from one unit, and on-the-fly override of all control aspects. The interface is user-friendly, so setup is fast and easy.
