Disclaimer - yea I aint doing it myself, but I like to understand things, and I like to at least talk the talk with my sparky - so dont get carried away here.... So from the reading around the traps, if I want to dim LED's - there are several ways of doing it, but I am guessing some better than others. For my house I am not having a huge amount of led's, its all c-bus, so DALI does not really seem to be the option for me... It just sounds more expensive and problematic with things like commissioning.. etc. So if I go down the path of using 0-10v outputs via a L5504AMP to a purpose built ballast, it appears I could set up some dimming on some leds. I have a couple of rooms, which I would like downlights in, but there is no space in the cavity to support the required spacing for heat protection, so the thought was to try and go a bit green anyway... The clipsal doco is a little on the short side, I can see that the ballasts are connected by a pair of wires - 1.5mm min - some kind of twisted cable, kept 150mm away from any 240v - that is fair and fine... I am assuming one ballast of proper description could control 6 or 12 led downlights - 3w or whatever, so I am not needing one ballast for each light. Do you need to program / commission / setup these ballasts in any way... They would be dum items wouldn't they? They receive 6v and know what to dim... Its not like a dali setup where each need to be given an ID to work... Correct ? Pricing on a osram ? or whatever brand ballast would be in the -0 mark - gee transformers electronic and iron core are , surely these things are not going to be too expensive.... So for my setup where there would be a dozen leds, one circuit, in 2-3 rooms, the cost of a 5504AMP at around 0 means this would be a more practical and cheaper way to implement than going down the dali path ? I might just go back to candles.... cheap, dirty and inefficient - but could spend lovely days actually making them.... Thanks
