Inside a new 6 colour LED disco style lamp. (plus modifications)

These disco style LED lamps seem to have come a long way since the first 3W ones that had a red, green and blue LED. This one has six LEDs red, orange, green, blue, pink and white. They are run from a small switchmode PSU based on discrete transistors at a voltage of 18V at 150mA which means that the 1W LEDs are only being driven at half a watt which is ample for this application and will result in cool running and a longer life.

The listing I bought this lamp from was:- http://www.ebay.co.uk/itm/151947698357

Note that most still seem to have just three LEDs, but the particular shape version shown in this video may have the 6 LEDs, although the listings seem to show just three colours.
