September 9, 2016 – Standard Products’ line of step-down transformers (order numbers range from 64656-64660) is designed to convert high-voltage power to low-voltage power, allowing 100-277V LED drivers to operate on 347V mains. These can be installed either in the junction box or directly on the luminaire.

Standard says these transformers are protected by “Vacuum Varnish Impregnation”—a bake process for noise attenuation and consistency of lighting in transformer applications.
