Sigma Surface-Mount shares the same light engine and features
a sleek mounting bezel for installation where recessing is not
possible.
Sigma is a 2-wire dimmable product that simplifies retrofit
installations by allowing the installer to take advantage of the
vessel's existing two wires (or duplex cabling). Sigma is also
compatible with some existing halogen dimmers which may
further simplify installation and minimize the project's wiring
complexity. Sigma's integrated low voltage AC bridge rectifier
permits its use with either 10-40VDC or 12V/24VAC supplied by
magnetic transformers.

OVERVIEW
Imtra PowerLED fixtures are uniquely suited for marine,
automotive and architectural lighting applications. They have
been engineered specifically to take advantage of the latest LED
(Light Emitting Diode) technology offering superior reliability,
minimal power consumption and far less radiated heat than
traditional incandescent light sources. When installed properly,
these products will provide years of flawless performance.
The Sigma series encompasses a common LSA (LED sub-
assembly) platform with different bezel options allowing the user
to choose a model that can easily replace existing lights whether
these are traditional halogen or older LED lights. The flush mount
models are provided with stainless steel mounting springs which
may be easily removed if a screw mount installation is required.
Sigma Small fits flush into a very common hole cutout size; may
be either screw or spring mounted.
Sigma Large shares the same light engine but is equipped with a
special adapter plate and larger diameter trim ring to fit a range
of larger hole cutout sizes; may be screw or spring mounted.
