Considering how best to update our living room (5.5m x 3.6m = 18ft x
12ft) lighting. *Currently it is lit by 3 x 60W R80 semi-recessed
adjustable-aim spotlights. R80 seems to have reached the end of their
shop-stocking life & in any case haven't been particularly reliable,
hence what next?

A quick scan the Screwfix catalog indicates that the GU10 (240v) &
MR16 (12v) (+?MR11) seem to be the only contenders (excluding LEDs
which maybe need more development time).

What are the pros & cons?

GU10s are for the pros to con the general populace...

If your a developer knocking up flats by the dozen theres a small
saving per point using GU10 over low voltage, no trafo and wiring
slightly quicker.

GU10s have horrfic efficiency lifespan and beam control.

LV is the real thing with good efficiency, excellent lifespan and
presion beam control.

How do you assess how many units are needed & where to place them in
the ceiling to obtain a good spread of light?

Ahhh, spread of light isn`t really reflector spotlites thing, trying
to ends up with loads of intense pools of light to try and generate
spread.

Feature a few of items, pictures or fireplace object on table,
doorways, put in adjustable, eyeball or similar, LV spots to light
these from an angle, fit a dimmer switch.

Pull the skirtings off and run a second or more lighting circuit to
2A sockets around walls, use combination of table and fllor and desk
lamps to give more light where it is needed, fit dimmer.


What do the letters & numbers mean - eg MR11 v MR16?


Multiple Reflector, though heard other explanantions.

The number is diameter in 1/8s of an inch MR16 is 2" MR11 is 1 3/8" ,
MR8 1"


Any advice, esp experiences of anyone doing a similar job, would be
most appreciated.

Look at places you like and try and take some tips from them , read
some glossy mags and coffee table books.
