I'm puzzled by your talk of alternatives, is there anyone here that
doesnt know what other types of lighting are available?

Think if people did "know what other types of lighting are available"
and crucially how to correctly select appropriate to task, wouldn`t
have a world full of worthless GU10s and hopeless retofits.

To reply by email change 'news' to my forename.

Clearly your lighting requirements for your porch and garden are
different from what you need chopping veg in the kitchen.

Unfortunate that you were unable to find appropraite fluro or LED
units for your application and had to adapt products to make them
suitable for use.

Has anyone tried the 7W G9 type? This is supposedly equivalent to a 35W
filament bulb. I've presently got a light with a halogen 25W G9, and
it's a bit too dim. I'm not sure what wattage filament lamp this is
equivalent to.

However, what I really want to use is the higher power 9W GU9.

I ordered one online a couple of months ago, but it still hasn't arrived
(apparently still on back order from the manufacturer). Has anyone used
one of these. Do they actually exist, or are they simply 'vapourware' at
present?

Going to guess thats a very tight fit in a G9 fitting, perhaps you
could look for an LV light fitting and burn an extra 11W and get the
intensity and higher colour temp along with good lamp lifer your
after.

Apart from the slight nuisance that they're slightly bigger than the
filament ones so you have to choose from a limited range of light
fittings that can take them, I've found Fluoro GU10s to be absolutely
fine. They give just as much light with less electrical power,

Afraid they don`t.

much more pleasant soft light that isn't a horrible green colour, and I
can hot-swap them without burning my fingers.

Guess your thinking of Cold Cathode FLuro CCFL which seems to be
chosen mathod fpr retrofit in GU10s which moticeably dosnt` have the
green cast of low quality CFL, if your halogen GU10s had a green cast
you have other problems... ;-)

Strongly suggest you look for a different lighting technology for any
new installations. Downlighters are so bad for general lighting, and
you may well find the EU outlaws the bulbs for them over the next 5
years (certainly the mains ones, and 12V may follow later).

Again , your suggestions for currently availabke suitable replacement
lighting?

Your source for beleiving MR16 will be "outlawed" within 5 years?

I did not see Andy make reference to MR16 in particular. However the
general EU timetable is described at the end of this document:

http://ec.europa.eu/energy/efficiency/ecodesign/doc/committee/2008_12...

I took the inference that he was refering to MR16 both LV and GU10
being ill advised for a new installation because of an uncertain
future.
The timetable relies on suitable alternatives being developed , for a
lot of uses of MR16 lamps there is no current or on the horizon
replacement.


Really there is some crap talked about lighting by the half informed.

Alas you need to include the law makers in that category.

Very regretably so.

Well, I'm not a photometer, but subjectively four low power fluorescent
GU10s on a lighting bar give plenty of light for me to sit at this computer,
just as the halogen ones did, so effectively they do the same job with much
lower power consumption.

And it' a more pleasant light, not being concentrated in tiny spots that
show up the most microscopic bits of muck on spectacle lenses.

I'll find out how tight if I ever receive one!

We bought the (ceiling) light because my wife liked it, but, at the
time, I did express my doubts as to whether the 25W halogen (which is
the maximum rating for that style of light) would really be bright
enough. The executive decision went against me, but the executive now
admits that I might have been right.

I took careful measurements of the existing lamp holder and its relation
to the rest of the inside of the light, and I reckoned that if I moved
it as far as possible (backwards) to the side of the light base plate,
the zig-zag glass tube of the Megaman 9W CFL bulb would be right in the
centre of the light bowl. Even though it is very chunky, there is about
1mm clearance with respect to the base plate. [If not, I could modify
things further.]

Even a 9W CFL should run a lot cooler than a 25W halogen. The only
problem is, does this lamp really exist? If not, as you suggest, I'll
have to consider changing the lamp holder - or even replacing the whole
light.

Might be easier to leave it be and fit additional concealed lighting
to make up the deficiency

No really. It's in a newly-built shower + toilet area, and I don't want
any more electrics than necessary. If the 9 watt GU9 fits, it should be
just about adequate. I've sent another chasing email to the vendor. It
was originally due 16 April!

Well the difficulty is who gets to decide what is "suitable". Many would
argue that there is currently no suitable replacement for a 100W GLS
bulb - the alternatives having poorer colour rendition and/or slow warm
up times, or incompatibility with dimmers, plus a range of other
problems. However this does not seem to have stopped the powers that be
from suggesting that these can be replaced with CFL substitutes.
