I am planning light fittings in my new house and trying to get to
grips with fluorescent lighting. I can visualise how much light a
standard incandescent lamp will give, but find it very hard to do with
fluorescent fittings, particularly the smaller tubes.

Is there a good rule of thumb for comparing the output?

says 730 lumens from a 60W incandescent

http://www.tlc-direct.co.uk/Technica...en_Compact.htm
says about 900 lumens from a 15W compact
(but the cheap ones are about 750 lumens)

says 880 lumens from a 13W tube (21 inches)
