In the process of getting my LOR controller to work last night I had some time to look at my bigW lights. I had always assumed the transformer went from 240V AC to say 12V DC. I now don't think this is the case. The transformer says AC-AC. I assume this means the transformer is going from 240V AC to 22V AC (stated output on transformer is 22V). From what I've read LED's operate in DC. So reading between the lines I'm assuming the multifunction controller (MFC) coverts from AC to DC as well as doing the flash operation. Seems like a long winded way of doing things to me but I guess being bigW and china it is the cheapest way to do it. I was hoping to just cut out the MFC and rejoin the wires. If all my assumptions are right I won't be able to do that now and will have to put a bridge on the MFC board like shown in the Wiki. I was told last night by a trusted source that using the dimming function on the LOR controller with lights that have transformers is not good for the controller. I have sent an email to LOR to get their opinion. I'm not too stressed about using the lights as just on/off. Has anybody out their got a LOR 240V controller they use with lights on a transformer and had any issues. PS. I got the LOR controller to work. It was the network cable. I was using a cat6 and then whilst waiting tried the cat5e they sent with the gear and it worked. Not sure if the cat6/cat5e is the difference or maybe my network cable is just stuffed. Still waiting on LOR for that response. Damn that 14 hour time difference. Frustrating at times. Good news is it works though.
