Converting LV MR16 Fixtures To MV GU10 - Safe?

[EViS]

I ordered 14 Philips Master LED bulbs for my kitchen and I'm seriously impressed! So it's time to replace all the other halogens in the house. However, some of the fixtures take LV MR16 bulbs so I have a couple of questions about converting these into GU10 LED's.

1) The LV fixtures in the bathroom have a glass cap which screws into the fixture keeping the bulb in place within the fitting. Any reason why GU10 LED bulbs couldn't be used here?
2) Some of the LV fixtures which have the round spring clips in place (or a glass cap as above) to hold the bulbs have stickers on the fixtures stating that only LV bulbs are to be used. Any reason for this safety warning and why GU10 halogens or LED's couldn't be installed?
3) There are a couple of LV fixtures which don't have spring toggles to hold the bulbs in place. Is the only option to change the entire fixture for an MV one?

If your transformers are compatable you could use these as a direct replacement MR16 LED Bulbs - BEST PRICES for MR16 LED Bulbs and LED Lighting I have never used them myself so I cannot give a pesonal recommendation though.

much better off with the proper LED fittings now like the halers or aurora.

least there fire rated and ip rated so you can fit the same style around the whole house
