All of our lighting is now LED. Imtra in the salon and heads because they had the correct sizes for our cutouts. Lumitec Moray Flex LED under all valances and gunnel, which is really great. Quick Marine for all of the bedrooms and companionway.
Lumitec in the hardtop and bridge overhang. DRSA in the engine room.
Lumitec underwater fixtures in transom.
Some on 110v transformers, some 24v DC.
All of the Lumitecs dim and or change color with cycling the on/off switch.
For all other dimming we're using DC dimmers from Blue Seas operated via Vimar momentary push switches, one for brighter, one for lower.
Everything is using just 2 wires, no separate dimming wires.
