Rated 4 out of 5 by Robus SELV Transformer Have bought several of these on occasions to replace existing failed units. Good value, easy to install, bit too soon to comment on reliability. Only question mark is method of cable restraint on input side - this is a push down ratchet type cover/restraint combined, and not the usual screw down cover/clamp solution. This can be a little difficult to remove or adjust, and could see how the plastic could break. 30 Dec 2015
Rated 4 out of 5 by Very good product Bought this to replace an existing single connection transformer which was pre wired. This one was an excellent replacement. Easy to fit and has a capacity to handle 3 light fittings. Only fitted this a few days ago so can't comment on it's long term reliability but feel confident it will do a job for some considerable time. 23 Nov 2015
Rated 5 out of 5 by Transformed bathroom Excellent value. Easily fitted. Instantly made bathroom brighter. 23 Nov 2015
Rated 5 out of 5 by Great value and easy to fit Bought this to replace a transformer that had blown in my existing system. This was very easy to fit, and would have replaced three of the previous ones that only had a single secondary. 9 Nov 2015

Suitable for LEDs?

Anybody tried this transformer with LEDs? I have tried to install LEDs and the transformer I have at present won't switch on with such a tiny load

Hi Nik1969,

This transformer is designed for use with 12v halogen lamps, it does work with some LED lamps but not all so I cannot recommend this transformer for your use.
