i have recently had a new kitchen done and used 24 LED lights from "Illumination" in Swords a few doors away from Eddie Rockets.....I would highly recommend them !! They cost 15 Euro each are connected by mains (not transformer), are waterproof so suitable for outside, kitchens, bathrooms etc...Also they have different colour filters on them so you can select red, blue, green, orange etc....They have 6 LEDs in each rated at 0.5Watt each so one light using 6 LEDs uses 6 X 0.5W = 3 W each....i.e. very low power. they come in differnt sizes also.
