Low voltage transformers are essential components in various lighting systems, and their performance can be significantly enhanced with the use of accessories such as dimmers, timers, and photocells. Dimmers allow for adjustable brightness levels on some lamps and fixtures, improving energy efficiency by up to 20%, while timers can automate lighting schedules, reducing unnecessary energy consumption. Photocells provide automatic control based on ambient light levels, ensuring optimal illumination while conserving energy during daylight hours.
