Help with spot lights!

Rileybaby

Can anyone help?

I have 3 spotlights which need updating. They are fitted to individual transformers ( pictured) and we're working fine. I have removed one of the spots from the transformer & replaced it with one of the new ones. I'm getting electricity to the live cable on the new fitting but not to the bulb - any one know why?

If your not sure why get an electrician in ...

Thanks dippypud. The transformers are already in I'm just attempting to educate myself and thought someone may be able to assist. It's only 2 wires 1 live 1 neutral into an electrical terminal block. Should be an easy DIY!

Well now you have found it's not easy diy.....lol. Seriously please take great care when dealing with electricity. The answer to this problem im assuming is you have probably purchased the wrong type of spot light in relation to your transformers as we cant see the spots that you bought this is only a best guess......might have been better to get a qualified electrician in to begin with lol.

Thanks DavidF I am making sure everything is switched off at the mains before touching the electrics! According to the technical information the supply voltage needs to be 220-240v -50hz which is what the transformer is!

I've had an electrician (2 actually) price the job then 1 turned it down as it was not worth his while and the other just didn't bother to turn up hence why I have researched & decided to have a go... I am also making sure that it will be checked by an electrician ( friends brother who's visiting for the day on Sunday) unfortunately I can't ask him to do the job though.

Are you sure about transformer output being 240? Transformer change voltage level and your normal voltaic house for circuits is 240v anyway so why would there be a transformer? Check transformer output and then compare against new spot lights voltage ht rating.

It's not clear from this - are you getting 240V AC to the 'transformer' input? And how are you checking the output to the bulb - should be ~12V AC which you can only test using a multimeter.

If no 12V to the bulb then you need a replacement transformer - about £4.

Better still, get rid of the transformer, and use 240V spotlights connected directly to the mains.

Hi Keith969 Thanks for your help. I think I'm getting 240v to the transformer But haven't yet ( will have today) tested with a multi meter to see what I'm getting at the bulb. Whilst getting rid of the transformers mouldy be ideal I think this is outside of my DIY skills & as I've said it doesn't appear a big enough job for an electrician to do!

Are you changing over to LED bulbs, and if so, what is the wattage of the bulbs i.e. 5w or 7w

Thanks for your help... I'm not sure what the voltage output of the transformer is I ( possibly wrongly) assumed that as it was already working to power spotlights then I could just swop the new ones in!

What do you mean by HT rating?

RB if you are changing over to LED bulbs, what is the total wattage of all the replacement bulbs?
