Hi in my new flat's hallway I have five GU5.3 MR16, 12v, 50w halogen, bulbs. The are controlled by a Varilight touch and remote control dimmer, the basic V-DIM model. I have some problems, the lights go on or off when switching other lights in the flat and some times they do not switch off completely but they have a weak light. I now tried to use Philips LED Master dimmable 7w MR16 spotlights but I have again problems to control the lights with the dimmer. Any ideas what can be the problem? Would it help if I instal the top model of Varilight, the V-PRO dimmer switch?

Is this something newly installed or a problem that has just occurred on circuit that has been fine for sometime?
My next move would be to check that the transformers are compatible or faulty.

It was installed when i bought the flat and i was never 100% sure how to operate it. I recently replaced the halogen with dimmable LED bulb but is still the same. Innitally i thought it was that the system was operating in its maximum capacity i.e. 5x50w=250w so installed LEDs 5x7w=35w. what would be a compatible transformer for this settings?
The normal set up would be one transformer per lamp, the transformer would require to be able to deal with the output of the lamp, in this case above 50W, the transformer also need to be able to dim at the required load.
Something like this http://www.screwfix.com/p/halolite-20-60va-low-voltage-electronic-transformer-240v/48058
They need to be accessible when installed and also require ventilation, so do not cover with thermal insulation.
Personally I would go down the LED route.

If the transformers are maximum rated at 35W then the lamps should be no greater than that, I would consider even lower than 35W lamps.
12V LED lamps, will require drivers rather than transformers, but the same principles regarding dimming and loading apply.
