Re: dimmable CFL

[Mal Lansell <mal@xxxxxxxxxxx>]

I'm having trouble following your messages - I think Yahoo is playing
up
because the one of your own that you quoted below hasn't shown up!

Anyway - I have to disagree that it's a bad example.  It's exactly the
kind of thing I have in mind when I talk about "Guest
Unfriendliness"
and having to explain things so they can be operated.

I have a similar situtation in my bathroom with X10 lights controlled
via a micromodule and standard pull cord - because they fade up, people
who don't notice pull the cord again which locks the brightness at the
low level.  They then don't know how to get the lights back on at full
brightness.  I really need to get it all replaced.

Multifunction-anything is a pain (try turning on a shower in a US hotel
- I think they must have a competition for bizarre plumbing over
there).  Interfaces should be simple and intuitive.
