Hi
I am going to fit four LV IP44 halogen spotlights in my bathroom
ceiling. The room is 190 * 175, and I am trying to decide on the best
positioning of the lights. I don't know whether to arrange the lights
equidistant from the centre of the ceiling, or equidistant from the
edges, IYSWIM.


There are several free illumination designer programs ... where you input
your room sizes & wall materials, and you can place as many lights and of
what types you want and it will calculate and visually show light spread &
shadows, you can play about as much as you want.

They are free .... Thron, Illuma, Osram etc. will send you the CD for
free.

Thanks... I have had a look at the Osram one and decided to have one
extra halogen light to make 5, plus extra illumination by the mirror,
and I think this should get rid of the shadows, and make the room
bright enough.

I have played about with the positioning but it's not easy to get an
idea of the effect without a ceiling! I have noticed that the floor is
incredibly bright but further up the walls it is quite dim. Perhaps
this effect will lessen once the ceiling is up. 60 degree bulbs will
probably help too.
