I have a load of down lights fitted throughout my home and no doubt they are costing me a fortune to have on.
I know there is an equivalent LED light that saves a lot of money but I can only find them in white – does anyone know where I can buy these lights in different colours?
I have different coloured LED lights in my garden but the connection is different. Its just an idea to make one or more areas a bit more ‘ambient’ 
Try ebaY.
The garden lights are most likely 24 volt, indoor lights are typically 120 volt. It is possible to get a transformer and install low-voltage lighting.
Your best bet may be to visit a lighting store and pump them for information.
What is this, I would like to bring it to my camera LED lighting.
