At work I have been developing an RGB LED and halogen mood lighting system called Energy Solutions ES LightNET.
It has been specifically designed for the luxury yacht market where 12V or 24V DC supplies are available.
It also has uses in off-grid and industrial applications where wind and solar power are
available to charge DC battery banks.
The main Energy Solutions LightNET page is at http://www.energy-solutions.co.uk/lightnet.
There is also the documentation and support portal at http://support.energy-solutions.co.uk.
Here you will find detailed documentation and data sheets for relating to the Energy Solutions ES LightNET lighting system and other modules that may be
used in electrical control and monitoring panels.
