Has anyone used a Futronix dimmer with a Screwfix transformer - such as screwfix code 51565? It claims to be dimmable with "resistive and inductive dimmers", and the Futronix does "leading edge dimming". I've already ordered the switch (P400) and plenty of transformers and am seeking reassurance that I've not bought incompatible products. Further details of the transformer are: I'm planning on using each transformer with 3 35w bulbs or 2 50w bulbs. 3 transformers on each circuit making each circuit within the 300w maximum allowed by the switch. Please let me know if I've got it all wrong before the electrician turns up so I've got time to sort it out! Jon.
