I have 2 x 35w halogen bulbs running from a 12v 105w transformer.
When I switch them on (standard on/off switch not dimmer switch), they blink on, go off then come back on and stay on.
If I switch them off and on again they come on immediately and stay on.
If I leave them off for a few seconds they go through the blinking on process when I switch them on.
Before replacing an Aurora transformer with a Varilight transformer they behaved perfectly normally.
What's the problem?
