The ultimate LED refit light; The Sigma Large PowerLED fixture mounts with either springs or screws. Its special adapter plate and large diameter trim ring permits installation in to a range of existing cut-out holes from 2.56″ (65mm) through 3.65″ 3.65″ (93mm). Stainless steel mounting springs are provided for interior mounting (e.g.  headliner-wrapped or paneled ceilings). For secure mounting in to hard ceilings or exterior locations, simply remove the springs and mount with #4 flathead screws. A 10-40VAC/DC universal input allows Sigma to be used with 12V, 24V, or 32V systems and for voltage supplied by magnetic AC transformer as well.

  • Optimized functionality with the Intervolt Switchmode dimmers*
  • Hole (cut-out) size matches popular halogen recessed spots
  • 10-40VAC/DC input voltage (from battery or magnetic transformer)
  • May be installed with springs or screws
  • Part of matching family (small, large, surface-mount fixture)
