I have an electrician wiring an extension for me. I have supplied sockets and switches and he is doing all the rest including wiring, testing and certification. The switches and sockets are from a reputable manufacturer and include a 2 gang dimmer switch. This has been assembled specially by the manufacturer as it contains 1 LED dimmer module controlling 6 x 6w LED downlights and 1 x conventional dimmer module controlling 4 x 33w halogen bulbs.
On installation, the electrician reported to me that the LED dimmer module didn't work. He swapped it out for "standard" dimmer module that he carried on his van; that worked perfectly. I have now got a replacement module from the manufacturer - that one doesn't work either. The conventional dimmer module is OK.
Unless the manufacturer has a serious quality problem with this batch, something is wrong with the wiring. But the electrician's own dimmer module works perfectly.
He is puzzled and I am puzzled. Is there an issue with some LED dimmer modules or a misunderstanding regarding the type of module - this one is supposed to switch automatically between leading and trailing edge.
