Fitted several of those GU10 lighting units to the kids bedrooms - 4 GU10's
in each! - after the honeymoon period of about 2 months when all the el
cheapo GU10's that come with the units started to pop, discovered GU10's
where about a fiver each in the local sheds...

then discovered screwfix do the cheapo 1500 hour (LOL) ones for about 3 quid
......

then discovered Tesco's do a 'value' version (1500 hour - LOL) for
1.98.......

Today I was in the local B&Q - they are flogging six packs for £5.98 ......
yep .... couldn't believe it, and they are pukka 2000 hour units ... so
chuffed I bought two six packs.

Hope this info helps

..... you may well be right - only time will tell!

I will say though that the units seem like the high quality 2000 hour units,
with ceramic base rather than the cheaper - er I mean lesser life - all
glass units.

OTOH, it spurred me to get the LED GU10s, they are *very* blue, even

Where do you get LED GU10s and at what price? Can you mix 'n' match 'ordinary'
and LED GU10s on the same fixture to give a mix ofblue and ordinary yellow
light?

TLC electrical for around 6 pounds each. (less than their list price,
don't know how come that happened and didn't ask g )

Yes you can mix and match them, the light output is dim compared with
a 50W, and only a little dimmer than a 20W, if this helps.

Are they really bright enough? the ones I have seen are not very bright
at all - probably about 10% of a real GU10. They are nice if you want
pretty-pretty but not much good for lighting anything up.

The ones I have are very slightly dimmer than a 20W Halogen. I agree
them not being bright enough on their own for most purposes, but
for our conservatory they seem to work fine. Being LED they are _very_
directional compared to even the narrow beam halogens, but after over
a week of them, I think I like them.

We have 2 fixtures in the 'leanto' conservatory (about 18ft by 8ft),
one at each end. One end contains the dining table, that has retained
its 3x50w Xenon lamps, and the other end with the TV has the 3x1.8w
LEDs. They provide fairly reasonable functional light without too much
glare.

I would agree with the fact that right now, they are best in most
cases for 'accent' lighting, we were unusual in only requiring a
fairly low level of light. Give it another couple of years and I
expect they'll be as good as compact fluorescents.

They have them in Homebase on display, yet are not for sale. They are there
to stop people burning themselves. Yellow, blue and I think green coloured
GU10 are available in Homebase for £7 plus, for two.

What they don't tell you is that it's 2000 hours total for all six :-)

IME the better s/fix ones (branded Osram IIRC) do actually last.
The cheaper ones don't.

If you are a man with some time available then it should be possible to
buy a batch of bulbs and prove the 2000 hours is a lie. Then get trading
standards to take on B&Q and Tesco.

It's outside of my knowledge of statistics but does anyone know how many
bulbs you would have to get and how short their lives would have to be to
get, say, 99% certain that the bulb are being misrepresented? How certain
would you have to be to put the matter 'beyond reasonable doubt'?

Yes. I've had some of the bulk packed own label ones from B&Q
before, and fitted three of them and then three Osram ones.

The B&Q ones failed within a day or two of each other, and the Osram
ones lasted about three times as long.

Don't quote me
.... but AIUI, the nnnn hours life is predicated
on the 50% 'Life'; one gets say 100 units and power
them 'ON' simultaneously, _when_ the 50th unit fails
that's the nnnn hour "Life". Note this doesn't mean
that _your_ bunch of things will last nnnn hours!
Someone, somewhere, somewhen will end up saying;-
'I bought these in YYYY and they've lasted eons -
while someone else is saying; - "I bought these yesterday
and they've failed already" {The retailer/manufacturer
is still saying truthfully ; 'the life is nnnn hours".

OK. I'm sure that if I were to buy a reasonable quantity of budget bulbs I
won't get anywhere near the figure. How short a life for the 50th bulb is
significant to prove that bulbs on average don't have the life stated?

Example:
3 years ago I bought a kitchen light fitting for one of the flats I run.
the bulbs were all out in 6 weeks. (say 8 hours a day max - winter)
That's about 350 hours tops. Since then I've replaced them once.
Even allowing for summer usage of nothing so say 4 hours a day over the
whole year. Say 18 months life (at least) say that's about 500 days at 4
hours /day = that's about 2000 hours.

I've seen GU10'S on a site called "lighting-direct" which look the same but
actually operate using LED's.............. cost £12+vat each but supposed to
do 35,000 hours! If that's the case, they might be worth a try. Mind you, I
don't know how bright they are but bike lights that use them seem pretty
bright.

Reminds me of the coffee machine I bought from Makro at GBP 14.99. The

Sure enough it made 12 cups.

I got a flyer yesterday - 27p each also guaranteed lifetime

the only problem is that you have to buy 1000

So you get some idea of how much mark up there was on your bargain
