Rated 5 out of 5 by from 12V transformer Used to replace a failed 12v transformer to run 5 LED down lights. Seems to work very well. Difficult to rate the reliability at this stage, as only just installed.

Rated 5 out of 5 by from Great Transformer This replaced a failed one on my kitchen lights. Bought the wrong one one initially but due to the late opening hours I was able to get it all sorted on the day. Thanks Screwfix

Rated 5 out of 5 by from Great little Transformer This is a great replacement for a faulty one we found that was 10 years old. Having terminal blocks rather than flying leads made connection very easy. Having three outputs on separate pairs of terminals made it easy to connect in a number of lamps (total less than 105VA though).

Rated 1 out of 5 by from Bizarre design fault This is a useful transformer on paper. But having purchased one for a project I realised it is almost unusable and it ended up new and unused in a rubble bag. The reasons is this: unbelievably, the transformer relies on small poorly moulded terminal screw blocks on the secondary side to secure the conductors. Fine, but that is all. There is no cable grip or clamp. No mechanical protection whatsoever. This means that when the transformer is pushed up through the down light hole you have no confidence in the integrity of these connections. Also, if ever the transformer is tugged through the down light hole during a lamp change or inspection this connection is vulnerable. On the primary side there is a cable clamp but it is a silly design, relying on plastic teeth to ratched the cover down on the cable. The teeth aren’t moulded deep enough so the clamp simply ‘bounces’ of the cable. It’s not fit for purpose. A shame as a usefully rated transformer with 3 secondary outputs is rendered unusable by sloppy design. Waste of time and money.

Rated 5 out of 5 by from Great Little Transformer Used this to hard wire some 'plug in' LED lights from the Swedish flat-pack place - works perfectly. Liked the three separate 'outs', plenty of room on the 'in' end too. Feels well made.

Rated 5 out of 5 by from Even beginners can use it I bought this to replace a faulty one that my electrician failed to replace. The instructions were very basic and easy to understand. I installed it myself, took about 10 minutes due to tripple checking I was doing it all correctly ( and yes the electrics were switched off) and now I have a set of working lights.
