Halogen/ LED Trafo problem

Just moved house and have a problem with exchanging all 12V 35W halogen bulbs, with 12V 5W LED bulbs.
The latter work well for about 5 minutes, then start to (very weakly) flutter. After another 5-10 minurtes, some of the bulbs turn off. When I switch off, and then on again, the bulbs light up - again for another 5-10 minutes, and then the problem repeats itself. I note on the transformers concerned (see attachment), the phrase 'for 20-105 watts'. This is achieved with 2 halogens (70W total), but not for 2 LED bulbs (10W total). Is this the problem? Why should too LOW wattage give problems with the trafo?

The lamp load is part of the active regulating circuit. It needs a minimum of 20w to regulate and run properly. You could change to 10w bulbs. If not.... you''d need to change out that driver.
