When converting from halogen downlights to LEDs, if it's going to be a difficult job either way, is it better to replace MR16 sockets + transformers with GU10 sockets or just to use LEDs that are designed for MR16 set-ups? (Assume that I already know that the specific transformer I have would work with the specific LEDs I would buy). And if I want to convert, where can I buy cheap GU10 sockets with Australian 3 pin plugs wired to them (without buying an entire "LED downlight kit")?
I went up in the roof space a few days ago and noticed that our halogen downlights do not have the legally required space around them, nor heat protectors. I want to be up to code, but I don't want big gaps in my insulation. For now, I've installed a smoke detector up there, and moved the insulation away from the lights where I can reach it but I'd like to replace them as soon as possible with LEDs. I've found some awesome LED comparisons
so I'm comfortable that I am finding acceptable options at around $25 a piece.
Our halogens are MR16, with an ATCO TM50-2 transformer wired to each. The transformer is connected to the mains via a 3-pin plug/socket, so we could replace the whole shebang without calling in an electrician. Alternatively, according to most of the websites I've found, the LEDs I am considering would work fine with this specific transformer. So I could just order MR16 bulbs and leave the current fitting as is.
In either case I don't
think I can pull the bulbs out through the ceiling to swap them out. The fittings look like this
(two pics because they are different in the kitchen vs the lounge). Nothing seems to unscrew or pull off. So if I have to get up into the roof space to put the new bulbs in anyway, I think it wouldn't be any harder to just replace the transformer/fitting set-up with GU10 sockets. But I am failing to find GU10 sockets with attached Australian 3-pin plugs (apart from finding very expensive full LED downlight kits that come with bulb and all). (I'm finding GU10 sockets without
plugs wired on for $1.50 or so a piece.)
Also, although it's not any more difficult to convert the MR16 system to GU10, is there any reason to do so? How much extra power does the transformer use? Does it get hot (i.e. do I need to worry about its proximity to the insulation once I've switched the bulbs from halogen to LED)?
If there's anything else I'm missing or any other tips anyone can give, I'd appreciate that too.
