Default Low voltage wire/cable suspended lighting

Hello.
I'm wanting to illuminate a large dark gloomy old room. 17th century, low
ceiling with exposed beams. Very little natural light.
I am thinking that something like this
http://www.lighting-direct.co.uk/l-v...c-70-rn-0.html
could be suspended between the beams and be almost invisible when in use.

I know little of the subject and would much appreciate any pointers or
comments.
The items in the above link seem somewhat expensive for the area I would
like to illuminate.
Would require probably 4 runs with 3 or 4 lamps on each run when combined
with wall lights and other free standing lighting.
Also, could the transformers be hidden tween ceiling/upstairs floor
(6"/150mm gap) and would this present any fire hazard?

I presume I could use 6mm stranded steel cable with proprietory lamps and
fixings.
How do I calculate the size and type of transformer required. Line lengths
can easily be calculated. The number of lamps & wattage etc. is not so
simple
Sorry, this is very vague and I am literally stabbing in the dark.
Any pertinent comments would be much appreciated.

Thank you,

Nick.


For cheaper prices, try here

They are nice in situations as you have described, but remember the head
room on low ceilings. These lamps get hot.

There are decorative transformers that fix to the sides of the beams and
don't spoil the look of the room. If you wish to hide the power supplies in
the voids, there should be no problem, but a word of warning again is, these
do get hot and are not suited to very tight spaces or places filled with
insulating materials. They do need some ventilation to prevent overheating.

It is best to go with the largest power supply you can get. This gives the
option to add or subtract lamps as and when needed. The calculation is
simply Power Supply Wattage divided by the Wattage of the lamps you want to
use. Example: 3 x 50W lamps needs a 150W transformer. Simple as that.

The link I have supplied to Mr Resistor will take you to the section on this
type lighting product. They supply everything needed to complete the
project, Transformers, lamp holders, tension wiring and spacers etc. I
think they can even supply the fixing screws, but don't hold me to that.

Have a look through the site and I'm sure you'll find it helpful. Have fun
with it all.
