Were they actually banned?

** In the same way that GLS lamp were.

By using the MEPS provision of the energy act.

GLS lamps were banned by artificially setting the MEPS just above ( about
10% ) what such lamps normally achieved.

CFLs easily complied, but so did ALL quartz halogen lamps - most of which
are PRIZE examples of bad lighting efficiency.

The similar MEPS rule for external power supplies was *very carefully* set
at the exact level that excluded transformer types in preference to SMPSs.

Wot a fucking scam.

Wow - I hate the warm ones that much I didn't think anyone would like
them! Different stroke I guess!

Heh... yep, each to their own

I've had to replace heaps in just a few years


if they're not an environmental (and health I should have said) hazard
why does the govt issue instructions about how they are to be disposed of?

**Points:

* I did not say they presented NO hazard.
* Given the long life and lower power consuption of CFLs, the amount of
mercury entering the environment (if disposed of improperly) from CFLs
is MUCH, MUCH lower than burning the amount of coal required to keep an
incandescent of equivalent light output operating.

they still emit radiation

[Trevor Wilson]

and according to you that will be in 10 years time..

**Quite likely. Efficiency of LEDs and CFLs is similar.

I dislike the "warm white". Some are even yellower than the incandescents
they're meant to replace.

However, the cool white (or daylight) ones did take a bit of getting used
to, after half a century of yellow night-times. But I'd never willingly go
back - the world looks quite different when you can see the blue in
things.

When triphosphours first came out an electrian suggest their long life and
improved brightness would be a benefit. Well it was to the manufacturer, I
bought a couple. Bright yes, Warm white YUK.
Cool white only way to go for these aging eyes. Am have difficulty finding
Cool white in cfls and LEDs but I will continue my search..

the cool seem too white to me and the warm too yellow. something in
between would be good

I recall hearing of someone who was suing for getting skin cancer on his
head allegedly caused by working under fluorescent tubes in an office
all day

Doesn't mean that he has a valid claim just because he claims that tho.

yeah of course he has to prove it

I prefer "warm white" myself. Each to his own, I guess. And I hate those
headlights in a lot of newer cars (halogen, I think) which are also
towards the blue end of the spectrum, rather than the warmer colours of
older cars. I find them very harsh on my eyes.

Also, the "warm white" of the LEDs I've used is noticeably bluer than
the "warm white" of the CFLs I've used.

**People claim all sorts of idiotic things every day. That does not make
those claims factual.

I buy my cool white CFLs in Woolworths. Most recently, a few months ago.

Right, the price should be competitive by then. Hopefully a little less.

I've replaced probably 6 or 8 so far. Some went bang & smoked, some went
phut & went black, some just stopped working.

Yep, just replaced a two year old one with very little use yesterday.

I'm now only installing Philips branded units - fingers crossed.

You'll need it! I bought two Phillips cfl's a couple of years ago. One
lasted a year, and when I went to replace it with the other it was dead from
new! And of course I no longer had the reciept :-(
Mirrabella I have found to be just as bad too, the electronics inside die
before the tube.

[Trevor]

Heh... yep, each to their own

That's why they make different color temp versions, and have done with
normal tubes before CFL's even existed.
My preference is by far for quad phospur long tubes. They put out a better
spread of light for the same energy, and a bettter spectrum spread as well.

they still emit radiation

But not enough to be of any concern. I guess you never watched an old CRT TV
or heaven forbid used a CRT computer monitor as they are far worse for
radiation emmision.

And what was the outcome of the case? Thrown out as he couldn't prove it was
not from sun exposure I bet. (FAR more likely)

Trevor.

 

[Trevor]

it hasn't really become cost effective yet, and I tried some, but the
output is too low.

For the incorrect ones you tried maybe, but there are LED's replacing 500W
halogen floodlights now. That's when you start to see serious energy savings
and huge heat reduction!

ok for desklamps tho.

Will be when the cost comes down. Not cost effective there yet IMO.

**Indeed. X-rays anyone?
