the light is cold to touch (heat is still generated - but through a heat sink) coloured lights are alot more efficiant then any other type i know of the 5W white leds are not rated for a very long life but all the other 5W and all the 1W are rated for 100,000 hours. a swith mode power supply will probabily be need to drive them efficaintly which adds to the already high cost.
