Knightsbridge 12V 20-60W Transformer, 60 W, Halogen Dimmable

Bought to replace a transformer in our Blauberg extractor fan over the bath - easy to connect up and now the light works again. Great stuff.

Fitted to run 2 x 35w halogen kitchen downlighters. Replaced a 20 + year old unit that had failed. Total job took 10 minutes, made easier with the pre-terminated cable ends (rather than just bared ends). So far the unit runs stably and cool. No dimming function in the set up so cannot comment on that side of the functionality. Excellent price and fast delivery.

This does the job but I should have bought one without wires. Because they are pre-attached (and not obvious how to remove them) it was necessary to connect to the mains using a connector block. After this I've bought ones to which mains and 12V wires can be attached. It is great value and, like I've mentioned, it works so no complaints about the functioning. But be sure you need to wires already attached.

Excellent replacement- I have gone without a full set of working spotlights for about 4yrs fearing what an electrician might charge to fix them. When I looked into this with a few YouTube videos the solution was easy!

Always have 'that extra transformer' for when you need it

Great like for like replacement

Bought this to replace a defunct transformer for my garden lights. Despite the replacement being much smaller, I connected it up and the lights work again, albeit a bit less bright. Can't comment on longevity, but the product seems to be suitable and was easy to install.

Easy to install - If you are not a qualified person, do not attempt to do this job. The last thing you want is to cause fire, electrocute yourself and what is worst, your wife shouting at you if you burn your house. I am an engineer; you don't need to be one to change this. It is a 5-minute job if you know how to do it. If you are a DIY confident person, you can do it. Otherwise, call a technician (electrician). If you are a technician I don't need to tell you anything, the transformers have a nice and manageable size, nothing like the old times. It is pretty light and easy to connect the terminals. It is not heavy. Make sure you are using the correct rating; those were 12V up to 60 W dimmable. I can't confirm if they are dimmable, I suppose they are, but I am using a standard switch. I just fit those transformers in case we want to update to a dimmable switch in the future.
