Spotlights

I have 2 spotlights, Halogen with transformers MR16 lamps, I want to change to LED. Can I get GU10 lamp holders and just take the Halogen transformer out and replace the lamp holder and wire , there is a small junction box with the Halogen wire coming out. Or is it better to get LED transformers to replace the halogens ?

MR16 lamps are typically 12V ac fed from a 230→12V low voltage transformer somewhere. There are plenty of MR16 12V led lamps available for replacements.

{Occasionally there were some 230V MR16 lamp, I believe; and there may be some led mains rated lamps available. Deprecated of course due to the danger of fitting the incorrect voltage rating lamps in the fittings.}

Pictures of what you have currently with any markings clearly readable on both luminaire and lamp would help.

EDIT: Re reading your original… It would be possible to rewire with the correct cable, terminal blocks etc.,. but asking here = you aren't competent to do so. LED replacement lamps or new luminaires is the way to go (safely).

Thank you. Can I just replace halogen transformers with LED transformers into the same junction box, or LED connection straight into junction box ?

Why do you think you need "LED transformers"? Can't you just plug the 12V LED MR16s into the existing sockets?

Not sure I understand the question. What "LED connection"? Why "or"?

You can replace the old halogen MR16 bulbs with LED MR16 bulbs while keeping the same lampholders.

Do you have two transformers - separate for each lampholder? Possibly you'll need to replace them as well as some transformers specify the minimum current and LED bulbs consume smaller current than halogens. However, if it comes to replacing transformers, instead, if you wish, you can replace the lampholders with GU10 ones and connect them to mains where transformes were connected.
