halogen down lights

[marklowry]

i wish to install 4 hologen 12v down lights in a small study
i have a celing rose already
is the following method correct

i will remove the celing rose and replace it with a junction box
from the switched live and neutral run a 1.5mm cable to the first transformer then dasy chain to each transformer
is this method correct and do i terminate the cable in the last transformer or do i return it back to the junction box
i will use chock boxes
thanks for any help

will the junction box be accessable or hidden under the floor?
you dont need to creat a ring, just loop from one light to the next until the end.

Why? If this is a workspace, fluorescent lighting would be much better and more economical.

12v

Why? Some transformers can blow as often as bulbs.

How do you propose to keep this accessible for maintenance and inspection?

1.5mm? Is the rest of the circuit in 1.5mm? Most arent.

Terminate. Lighting isnt done in rings, and if it was, this isnt how the ring would look.

As long as the junction boxes are accessible and not just buried under a floor, be it from a loft above or via pulling them out through the downlight holes below, what you propose sounds fine.

As Steve said, don't try to wire the fittings in a ring. However, contrary to what he said, I agree with your decision to go with 12v lamps and transformers. They provide a better quality light and are more efficient in producing that light than the 230v halogen dichroics.

Why do you want a dark room with four bright spots in to study in?

Only joking it all sounds fine to me apart from the ring bit.

But seriously there are better types of ways of lighting a study than spots

You should maintain earth continuity throughout the new mains cable too.

thanks for all the replys
all connections will be accessible via the loft
the wife wants halogen lights so thats what its going to be

the wire i am using is 1.5mm because i have some,but the original wire is just 1.00mm
is this ok
thanks
