The ultimate LED refit light; Sigma is a full featured LED down light that is
dimmable using the vessel's existing 2-wire boat cable and is also compatible
with some existing halogen digital dimmers. Sigma’s hole cut-out size is similar
to many of the legacy halogen down lights that it is designed to replace. Sigma
is supplied with springs 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 s.steel 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.
