RE: CBUS and CFL's

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

I've seen cold cathode lamps that replace GU10s and they produce a
good
light output while reducing energy use and having a long life. Non dimmable
unfortunately and physically longer than standard lamps so can stick out
which ruins the aesthetics in some fittings. My building warrant pre-dates
the latest regs & I'm using a combination of lighting controls and
CFL's in
utility areas as my method of compliance with the less stringent energy
efficiency requirements. Principle rooms in the new house have 800W (LV
downlights, table lamps & feature lights) or more if every lamp was on
at
full brightness but this will not be possible with the scenes that I will
be
programming. I also wanted full dimming control to get some nice smooth
transition when lights switch on & off or change from one scene to
another -
IMO this is just as important as the final light levels for a scene and
simply switching circuits would ruin the effect.

The building control people seem to have really jumped the gun on this one
-
the CFL lamps are absolutely not the right technology to use, but the
better
alternatives are not quite ready for the mainstream.

I use a CFL in each of the places in the house where I don't do stuff like
reading, working on the PC etc - in the hallway, front porch, cupboards and
so on, so I'm not against the technology itself: I just find the light from
them to be sickly, washed out and just depressing to spend time in.

LED lighting on the other hand is crisp, clear, bright and pleasant. just
not *quite* bright enough yet.

I have read about some really over the top lighting installs in the past,
consuming kilowatts per room with 30-40 downlighters at 50W a pop. but
insisting that everyone uses these pallid CFL lamps instead. blech.
