Have u tried philips 7w LEDs ? Tried a wee experiment in a bathroom with 3 gu10 fittings already fitted. Fitted 1 osram 3w replacement and checked the output on a light meter,the led put out about 2/3 lux level of a gu10 halogen.reckoned I would need an extra fitting to get the same light level using LEDs. Anything less than 7w doesn't seem bright enough for general lighting.I rate halers.
