Hi LED E27 lamps from China are permitted, what about adaptor? I can't find any info to say that they are compliant. Thanks.

Any such adapters are unlikely to be compliant. As the screw thread must be connected to neutral. But there is a 50% chance it will actually be live.

Compliance is more than that, the thread has to not be connected to anything, the connection comes from a second tab at the bottom that the thread hits when almost all the way in, so that there is no exposed thread when it finally does connect.

Most chinese holders are a single metal thread connected to one of the incoming terminals. Also with insufficiant shrouding to prevent fingers getting into it. I couldnt find a specific AS/NSZ for lampholders when I was last looking, but there is a euro one that is what you have to follow, which has all the stuff in it about the terminals etc. Remember in most of europe they have non polarized outlets so they have no way of knowing which side the thread or the center contact will connect to, hence the safety requirements about not being able to touch it when the lamp is half in.

I think the idea is the lamp is screwed in to the adaptor first, but point taken that they are not OK. There are a bunch of various types on trademe now. Vendors are taking a risk.

I end to err on the side of caution when it comes to 240V, people getting electrocuted or my house burning down.

Those adapters are shady - there is a reason you can't buy them in most shops.

A significant percentage of what's on TM, particularly oddities like these sorts of converters, are just straight from AliExpress\DealExtreme etc. So should you wish to take the risk (I wouldn't for the reasons above) then you could just cut out the middle man and save a bunch of money, and also avoid giving TM more money.

All the Dichroic-style LEDs I can find with GU10 connectors seem to be oddball brands, probably a good reason to replace the entire fitting here with something less oddball that takes B22s.

There are plenty of GU10 lamps at physical retailers, and they are usually well enough schooled on the regs to know what they need to have, unlike the from a garage trademe sellers which make buying from there so damn hard.

I got a whole lot of them for about $5 each at mitre 10 that were on clearance, and bunnings have the click branded ones for not much more than that. There are also some slightly more expensive osram ones that are dimmable, but I have not tried them out yet.

Thanks for comments. We all agree the adaptors are illegal.
