The housing association insisted on a splashproof luminare in the
bog -
I
only just managed to persuade the electrician not to put one in the
kitchen
too.

Who gives a fuck what they insist on? When he leaves, remove it.

A few years ago Morrisons did a special offer of CFLs for 99p - then
extended the offer to buy one get one free, at that price I filled a
couple
of carrier bags.

While LED bulbs are still at least 9.99 and I'd need 3 to give the
same
light as a CFL, there isn't much incentive to make the change.

15 gives you 150W equivalent. 10 gives you 100W equivalent. 3
gives
you 50W equivalent. And that's including postage.

There's not much point figuring out a conversion for the enclosed
unit
that
I have 2 spare ballasts and 2 spare tubes for - way back when I
bought
replacement parts, there weren't the options that are available now.

Might start visiting the dump again - if I can salvage a few GU10
fittings,
Home Bargains sometimes have 5W bulbs that are allegedly equal to
40W -
3
of
those in the bog fitting should be plenty.

LEDs that fit in GU10s run very hot and don't last long. I've gone
off
CREE LEDs and go for the corn on the cob ones. Hundreds of tiny SMD
LEDs.

HB have had 2 types - a 4W with 4 SMD LEDs and a very tiny switcher PCB
inside the body, and a 5W one with 24 simpler SMD LEDs and a wattless
dropper.

Several in an enclosure could be a heat problem, so I'd prefer the
watless
dropper type when they have any in.

I'd recommend you go for whatever has more LEDs. The big 1-2W LEDs
simply
cannot be cooled well enough.

The 4W one has 4x lens capped LEDs with a molded lens plate that fits
over
the lot so you don't get 4 little beams,

That sounds like CREE LEDs. The kind I have in GU10 that last about 4-6
months.

the 5W variety has 24 simple SMD
LEDs with no lens as such - much better spread of light IWHT.

Yes. I like the corn on the cob as the light comes out all round it and
the end, just like a CFL.


They're on a flat disc, not corn cob. Apart from H4 replacements I've only
seen corn cobs advertised in the Indian EFY magazine.

The fuckwit electrician that installed the luminare fitted the wrong
ballast, from day one the florescent tube did a fair bit of buzzing
and
flickering before it started - it got so much worse that I had a
problem
waiting for the light to come on so I could piss!

I tried an electronic starter, there was still a long wait but at
least
the
light came on eventually without a major drama.

When the tube refused to strike at all, I bought a new tube and an
electronic ballast on Ebay. The old tube worked OK with the
electronic
ballast and I got more or less its life expectancy from there.

When the fire alarm contractors did the corridor lights, I won a
couple
of
spare electronic ballasts and tubes, as well as the photo-sensor I
mentioned
on chatter.

When one of my fluorescent fittings dies, I remove the fitting and fit
something that takes LEDs.

I
only just managed to persuade the electrician not to put one in the
kitchen
too.

Look on Ebay, there are much cheaper better ones. But buy them from a UK

UK). Otherwise the distance selling regulations won't help you if they
fail.


Most of what I've seen on Ebay that I'd want to order, is from China etc.

Royal Mail extorts a racketeering 'handling charge' for collecting any duty.

Its pretty much put me off bothering.

LED bulbs are plentiful on Ebay. There are loads of UK sellers who have imported thousands and sell them from this country, with our consumer protection laws applying.

How many potheads does it take to change a light bulb?
Two. One to hold the bulb against the socket, and the other to smoke up until the room starts spinning.

A few years ago I ordered an electronics kit from Jaycar in Australia.

The duty to be collected was about 4 - that and the Royal Mail 'handling

Its pretty much blackmail - cough up the extortionate charge or you don't

By "duty" I assume you mean import taxes. That shouldn't occur unless the item is over about 30-50. Secondly any decent seller will write it as "gift" and value "$10".

It's simple. If you receive something from Ebay with unexpected duty, then don't pay. It goes back to the seller at their expense.

Not a problem, Ian! If you want to learn anything about Power Factor
have a look at....

http://en.wikipedia.org/wiki/Power_factor

Note in the first para, where they talk about "or due to a non-linear
load " they are talking about any circuit the contains a capacitor
and/or an inductor/transformer and/or a transistorised circuit.

I glanced over it .... didn't see anything to go against my " *OPINION*
" .... but I could be wrong!!

Most of what I've seen on Ebay that I'd want to order, is from China
etc.

LED bulbs are plentiful on Ebay. There are loads of UK sellers who
have
imported thousands and sell them from this country, with our consumer
protection laws applying.

Royal Mail extorts a racketeering 'handling charge' for collecting
any
duty.

Its pretty much put me off bothering.

What are you talking about?

A few years ago I ordered an electronics kit from Jaycar in Australia.

The duty to be collected was about 4 - that and the Royal Mail
'handling
charge' for collecting it came to more than 50% of what I paid for the
kit!

Its pretty much blackmail - cough up the extortionate charge or you
don't
get your goods - which will eventually be disposed of.

By "duty" I assume you mean import taxes. That shouldn't occur unless
the
item is over about 30-50. Secondly any decent seller will write it as
"gift" and value "$10".

Well Jaycar didn't, and I got mugged by RM.

It's simple. If you receive something from Ebay with unexpected duty,
then don't pay. It goes back to the seller at their expense.


Most places I order from won't send the goods till after payment clears.

Snip

Its not power factor as I understood it to be, but it appears to have
become trendy to refer to any AC current waveform distortion as a PF
issue.

In any event; the circuitry to eliminate the current blips as the
rectifier tops up the reservoir has become generally referred to as
power factor correction.

Well then, what "has become generally referred to as power factor
correction" is *WRONG*

Nevertheless - your OPINION appears to be in the minority.

Does not mean my OPINION is wrong!!

Never said it did - but you do seem a bit over keen to post your OPINION
where facts would be more appropriate.

Not a problem, Ian! If you want to learn anything about Power Factor have
a look at....

http://en.wikipedia.org/wiki/Power_factor

Note in the first para, where they talk about "or due to a non-linear load
" they are talking about any circuit the contains a capacitor and/or an
inductor/transformer and/or a transistorised circuit.

I glanced over it .... didn't see anything to go against my " *OPINION* "
.... but I could be wrong!!


Till the next time you post your OPINION as fact then.

Sure it won't be long.

Yes, but we were discussing the duty open RECEIPT.

If you read down a bit you see they list capacitors & inductors under
linear loads. Here linear means e=Zi where Z is the impedence & e & i are
the instantaneous voltage & current. Basically, you put a sine wave
voltage in, you get a sine wave current with a possible phase shift out.
Non-linear devices give current that has harmonics or has term like i^2,
i^3 or v^2 etc. or where Z is a function of voltage or current. e.g.
distortion to the sine wave other than a simple phase shift.

Z /can/ depend on frequency but not voltage or current, so its a touch
more messy if the input isn't a sine wave.

For linear loads
(1) pf = real power/apparent power, real power= RMS(e x i),
appearant power = RMS(e) x RMS(i)
and
(2) pf = cos(phi)
are equivalent. For non-linear loads (2) is less usefull so you either
need a new term or you need to generalize from (1) which seems to be what
was done. C'est la vie say the old folks.
