Planning on fitting some downlighters in the kitchen and hallway ceilings.
Kitchen is 3.25m x 2.20m (worktop in a U-shape, wallunits on two walls) and
hallway is L-shaped - 2.45m x 1.85m with 0.90m x 0.95m taken off one corner.
Not worried about the ability to dim them, just want to switch them on and
off. Our ceilings are quite low (2.3m) so I have a feeling we would need
need a number of downlights spaced out around the areas involved to ensure
that the light produced is evenly spread out. Was thinking about having
three downlights in the hallway and four/five downlights in the kitchen (all
with wide beam bulbs).

Looking for recommendations on whether to use mains voltage (240v) lights or
low voltage (12v) lights and also depending on the type used how many would
be required to sufficiently light the areas without casting lots of shadows.
At the minute I am swaying towards LV ones.

Plus point I have for the mains downlighters is that they are easier to wire
up but on the down side they have a high wattage - 50W or 35W. I am also led
to believe the bulbs don't last as long as LV ones.

Plus points I have for the low voltage downlighters is that the bulbs last
longer and are more energy efficient. I am also told they give off a whiter
light. On the downside these may be a 'little' harder to wire up, and a
transformer needs to be used, but this shouldn't be too hard in my case as
the floorboards are already up in the rooms above. The trouble I have with
the LV lights is that I haven't got a clue how much light they produce!

Any advice welcomed.

Dave

Get the Panasonic mains flourescent reflector bulbs in downlighters.
80mm size, 20w, protrude enough to give a spread of light rather than a
small pool on the floor.

If you must install halogen downlighters, then install LV. Mains ones are an
environmental catastrophe, whilst LV ones are only an environmental
disaster.

Christian.

same deal financially as well. Cost of fittings is generally very
small compared to run cost with multibulb halogen setups.

And if you can, put them on 2 switches so you can select 3 different
brightness levels. Much more comfortable, and costs less too.

Mains bulbs cost more, dont last as long, break more easily, and are
less efficient.

I though halogen lights used far less electricity compared to normal
lights.

They just produce a bit more light than conventional incandescents
because they can run hotter without burning out.

They can be manufactured to either be _slightly_ more efficient,
or to last longer.

The very low efficiency here comes from using the wrong light for
the wrong application. They are useless for general lighting, which
is what people commonly use them for, so you'll see people make
comments like needing 300W to light up a small bathroom, which
would probably be brighter with a conventional 100W lamp, except
for the half a dozen floor tiles right under the downlighters which
are being used as a reflector to light up the rest of the room.

So whilst halogen lamps are _slightly_ more efficient, using
halogen downlighters for general lighting is extremely inefficient.

The correct use for such lamps would be for task lighting or
accent lighting (lighting a flower display, or a varse, or
similar). In such a case, the main general lighting would be
provided by something more suitable. Another example where
they might provide general lighting would be when deployed as
wall-washers, with the wall being a bright colour to act as a
soft reflector.

Where is it possible to find these bulbs - the Panasonic site has no mention
of lighting.
