I'm still confused!!!!! My electrician said he was not a fan of the 11w ones as they are not very bright and give off that yellowish light. Is he just being difficult?
my electrician just said the same (based on what he was told only)
does anyone actually have some installed?
For those wanting a dimmable compact fluorescent downlight, the Megaman GU10 11 Watt Dimmable Bulb will be available late March 2007. Visit www.neco.com.au/product.asp?pID=638 :
these are $40 plus you have to buy the fitting on top of this $10?
beacon lighting said they can get in dimmeable
may be able to get them in now
but its a new untested product
price around the same as above approx far as I know
they said light in cfl is fine
dimmeable halogens are only $13 I think
so its a big commitment to get the cfls throughout?

A suggestion. Rather than go in and hit the whole of house go through one area at a time and design lighting to suit that area. It may cost more in the long run, however you open up numerous options.
We have just moved in and admittedly have an advantage with sparkys on tap to us. However we are doing the family room / kitchen area out in downlights and low energy downlights in some spectacular effects.
Next is the stairwell which we will use LED with different colour effects depending on the day etc.
Best approach there is DT.
re the CFL 11w - There have a been a few reviews of various lights in the renew mag of late- grab a copy and see what they say.

I was reading that a cfl light will save you an estimated $12 over a year
over a halogen light so within a few years the difference in initial costs is made up, plus youre helping the environment yay!
also read the cfl give out a wider light than halogen which is more directional
given I hate standard flourescent lights (so strong and bright eek!)
are cfl's anything like that? presumably and hopefully not

Bec your lucky - the CFL's are not like the stark old strip fluros of old.
They are not the same as Halogen, BUT they are lots cheaper to run.
Some CFLs come in cool white, warm white and other colours so find one that you like the look of in the shop, and with some reflectors etc, they can be made to do a similar task.
running costs. 1 x 50w Halogen is said to cost on average $10 per year to run. 1 x CFL of the same Lumens (which is light output) is about $2.30 per year to run.

Based on what we saw, we found the opposite - that CFL downlights were not as bright, and not as wide of a beam (they basically only shone straight down).
We ended up going for the usual halogens at this stage, and once the technology improves we will look at swapping over.

do cfl's emit more emf's
Yes
But hey - emf, versus to many solar rays - hmm - we can find the balance.
If the emf's can be kept to a minimum - and far enough away - then I think it is a good compromise
hmmm..Im now back to wondering about led lights instead....
where do they fit into the scheme of things, for the environment, price, light they give out, etc
also do led lights get really hot?
which are the downlights that get really hot and have caused fires when blowin insulation was placed too near to them?
The downlights that run hot are the halogens. From what i've read about leds, the current generation are not bright enough but advances are being made with leds so they might be a solution in the future.
I'm in a similar dilemma, I'm keen on using GU10 downlights as you can use CFLs in them, but I've been told that they do not offer as much light as the 12V MR16s. Other factor is that we have higher ceilings (2.7m) and we've been told that using GU10s would not provide sufficient lighting. Would this be correct? Or would you compensate this with additional downlights? One of the rooms is 4 x 7m and the plan shows 8 d/l, would this be enough if we use GU10s?
two timber floor people have commented that downlights will show
up any marks/scratches on floors far more than normal lights, I suppose cos of their directional light..
do cfl give more wider light than standard downlights?
-----------------------------------------------------------------------------------------
(edit) dont panic found the answer (I actually posted it )
cfl give out a wider light than halogen which is more directional
does anyone actually have cfl downlights in their house and can comment on them?

Do you have an LED downlight that gives the same light output as a 50W halogen? I'm not talking about light intensity, as a narrow beam will give me a high intensity, but total light output.
Asking the same question a different way, how many lumens does a conventional 50 W quartz halogen give off and how many lumens does your LED light give off, and what is the wattage? Finally, how much would such a light cost and how long would it last?
Cheers,

With the recent release of our new low energy LED downlights, we now have low-energy LED lighting options for every application for any project.
Let me know if you would like any further info.

So, finally LED lights have caught up with CFLs. The advantages that I see for LED lights are
1) They last longer
2) They are instantly on and to full intensity
The advantages I see for CFLs are:
1) Cheaper
2) Look better (80 mm trim versus 120 mm trim)
I notice that the LED (and CFL) for the wattage mentioned are not dimmable. So if you want dimmable, halogen has a place.
My (interim) summary, use CLF or LED for main lighting and supplementary halogen lights where you want dimmable or short term task lighting (eg. over kitchen benchtop).
Thanks superlight for enlightening (:)) us on this topic.
So, how much do they cost and how long are they expected to last? Also, do they work directly off 240 V.
Cheers,
Casa
