I need to introduce a source of light into an otherwise dingy hall -
without resorting to leaving lights on all day.

As far as I can see there are 2 options the Monodraught sun pipe -
http://www.sunpipe.co.uk/sunpipe/domestic/index.php and the Suntile sun
tile (!) http://www.suntileuk.com/home.php.

I had a look at both at the Grand Designs show in London and of course
the sun pipe appears to be much more sturdily built but has a price to
match.

Does anyone in here have any strong thoughts on either route or have
any other suggestions?
