**The only accurate point in that beat-up was the one about dimmers.
Sheesh! What a load of complete bollocks. My oldest CFLs are in my
bathrooms. Not only do they STILL deliver more light than the
incandescents they replaced (measured with a light meter and a spare
incandescent), they use less than 30% of the energy, haven't had to be
replaced (previous lamps lasted around 6 months) and have similar
colour balance. My only complaint is the slow (about 45 second) warm up
time in the middle of Winter.
Talk about a storm in a teacup. My only CFL failure was when a possum
sat on a naked lamp in the garage. I now have them in every fitting
that will take them.
Having said all that, I agree that CFLs are far from perfect. LEDs,
when they sort out the high power problems, should adress those issues
nicely.
A lot won't fit in oyster fittings, if they do they overheat in non
vented oyster fittings
**Then you have several choices:
* Stockpile a handful of incandescents.
* Choose another fitting.
* Buy one of the newer halogens, which the gummint seems to think are OK.
One of my light fittings won't take a CFL either. I don't use it.
I also have a bunch of incredibly stupid, wasteful 50 Watt halogen
downlights. I rarely use them too. Dumbest light fitting ever designed.
Well, it's OK for lighting a specific workspace (like the kitchen sink),
but that's about it. How on Earth designers thought they'd be a good idea
for space lighting is beyond belief.
Our main lighting is 3 50 watt halogens in the living room. Ordinary
globes and CFLs won't work because of a very high ceiling (3.5 metres on
one side), the light from the halogens focussed into the area where we sit
in the evening. The lights are on from about 6pm in the winter 8pm in the
summer to about 11pm, ie at worst 750watt hours per day. Using CFLs would
save at most 500watt hours per day, probably less. If LEDs ever become
available at reasonable cost, I'll consider them, but CFLs just don't cut
it and the savings are quite minor.
Now, when the hot water system blew up 6 months back, I replaced it with a
heat pump system. After the government rebates it cost less than a
conventional electric system. The 2 electric bills that I have had since
it was installed showed a savings of 7.5 and 5.0 Kw hours per day. Now
that is real savings both in my pocket and for the environment.
**I've done some back-of-the-napkin calcs on the hot water system thing and
if I swap my off-peak system out, I'll lose big time. I don't have my bill
close to hand, but I usually pay around $20.00/quarter for hot water.
