Default Why eco-light bulbs aren't what they seem

Think those compact fluorescent bulbs are not as bright as the old-style
lights they replaced? You are probably not imagining it.

A guide to the amount of light given by a CFL bulb is given on its box
as a comparison to the wattage of an incandescent bulb. But the European
Commission says in a FAQ document this can be misleading.

"Currently, exaggerated claims are often made on the packaging about the
light output of compact fluorescent lamps - for example that an
11-12-watt compact fluorescent lamp would be the equivalent of a 60-watt
incandescent, which is not true."

You must be a incandesant bulb salesman. Here is the US we dont share
your ignorant line, we have independant magazines that have verified
the truth, Consumer Reports, Popular Mechanics did reviews,
Incandesants are nothing but electric heaters that output light as a
byproduct. Of course you know that only 4-6% of the energy used by an
incandesant is light you can actualy see, the rest is heat, Edison
made the thing, its time it dies.

I think that we have gone well beyond your limited understanding on the
subject several times in this NG

CFLs are certainly better in terms of light output / watt (well for a
time, anyway), but not suitable for all applications, and some of us
resent not having the choice to use what is appropriate for a particular
application

Here in the UK, we see you septics as being the guzzlers par excellence,
unparalleled in your power consumption / head

Sorry, what were you saying about ignorance and truth ?

go and sort your ****ing country out then ...

Anyone would forgive you for believing that Edison invented the lightbulb,
since you're American. A chap called Joseph Swean got there first. Insular
countries tend to believe it was one of their nationals who invented the
light bulb. I forget the name of the equivalent Russian inventor?

Mine from tesco said that, trouble is why compare them with something
nobody every uses ? Because most people don't bother to read the small
print.
I believe soft-tone bulbs were those coloured ones, which are
obviously less efficient.

That's what CFL's in this country have always been compared with.
As virtually no one uses softone lamps, that's why most people have
been very disappointed with their first experience. Feit is the
only brand I've come across with honest power equivalency markings.

Otherwise, ignore the markings on the box, and use a ratio of 4:1
for replacing GLS, 3:1 for replacing large reflector lamps, and 2:1
for small reflector lamps.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Fredxx" saying
something like:

light bulbs

I forget the name of the equivalent Russian inventor?


Russian claims seem to centre around Yablochkov, although it was
actually a carbon arc lamp in his case. The only originality was the
self-regulating nature of the carbon gap, as carbon arc lamps had been
around for a while.

The Russians claim everything, including the steam locomotive.

"historians Robert Friedel and Paul Israel [3] list 22 inventors of
incandescent lamps prior to Joseph Wilson Swan and Thomas Edison." (from
wikipedia).

I can believe it, too - the person recognised as inventing something
according to popular history is usually right at the end of a long line of
folks (powered flight, radio and the steam loco are all fun ones to dig
into!) who already have something that works - and even then a lot of
recognised 'inventions' are often the bringing-together of several
existing technologies or ideas (i.e. the recognised 'inventor' is little
more than the adult equivalent of a kid playing with Lego)

Having spent time in several countries, I reckon they're all insular and
over-protective when it comes to their technological history.

Which is the best to use on a dimmer


IME, none. There are dimmable ones, some which run on a dimmer and

a minimum load below which they don't work, and with that typically
being 40W and the CFL being less than that, the dimmer won't work
anyway.

If you want dimming, forget about retrofit CFLs and go with either
dimming fluorescents on electronic ballasts, or dimming 12V halogens
(although they may also be banned at some point in the future).
LEDs may eventually be the way to go here, but they aren't there
yet (unless you have lots of money, or you want to make the whole
thing yourself from individual LED parts, and you don't need lots
of light).

I'm planning on converting some mains lights (3 lamp pendant and two
single lamp wall lights) which are on a dimmer to use 12V halogen
capsules instead. I'm making up a set of halogen capsule (G5.3) to
bayonet cap (B22d) adaptors. Currently made two, and just got a 3rd
bayonet cap base from a dead lamp (I'm limited by rate at which I
find dead bayonet cap lamps from which I can reuse the lamp caps).

and has the best glow nearest to a normal bulb?


That's subjective. You would need to more accurately define which
properies of a normal bulb you want to match.

Ha, I just had a wonderful idea for an electromechanical dimmer, with a
motorised shield that lowers down over the CFL by an amount proportional
to a dimmer switch setting...

I saw a fascinating show on the TV a couple of weeks ago where one of the
presenters made an oven using one or two 100W incandescent bulbs, and roasted a
chicken in it, using a fraction of the energy of a conventional oven. *I was
most impressed.


Nothing new or impressive there. Slow cookers have been around for

Note that US filament lamps are more efficient than UK ones,
because their 120V mains is nearer the ideal voltage for a
filament lamp (55V for a 100W lamp) than our 230/240V mains.
Also, their lamps are overrun (750hrs) compared with ours (1000hrs),
which also makes theirs more efficient.
So 3:1 is probably about right for them.

Not very good picture, but...
http://www.cucumber.demon.co.uk/lights/adapter.jpg

I was going to pot them with something (thought about cement/mortar).
In the end, the short length of wire and tight ptfe insulation is
just about robust enough to push a lamp capsule in without it
collapsing.

When searching around, I did find an ES version of this, but not BC.

And if you are in a rush for the other two dead lamps let me know. There two
in my van from work today.


Probably not worth the postage! It will be after Christmas when I
complete the job, and I'll probably have enough by then, thanks.

I'm planning on converting some mains lights (3 lamp pendant and two
single lamp wall lights) which are on a dimmer to use 12V halogen
capsules instead. I'm making up a set of halogen capsule (G5.3) to
bayonet cap (B22d) adaptors. Currently made two, and just got a 3rd
bayonet cap base from a dead lamp (I'm limited by rate at which I
find dead bayonet cap lamps from which I can reuse the lamp caps).


Any chance of a photo of these adaptors please?


Not very good picture, but...

I was going to pot them with something (thought about cement/mortar).
In the end, the short length of wire and tight ptfe insulation is
just about robust enough to push a lamp capsule in without it
collapsing.

Very interesting. Thank you.

Did you just solder the two leads up together and then wrap them in
insulation?

I've been cooking like that for a long time, just not chicken. Sheep,
cow, pig, fish. all kinds of game ... far better than in a
conventional oven.

Nothing new or impressive there. Slow cookers have been around for
years.


Yeah, but have you ever made one from scratch?


I have. Not for cooking originally but for melting beeswax and warming
honey in bulk. It's very easy.

I just thought it was rather neat to make an oven powered by a light bulb,
that's all. *As I recall, it didn't take too much longer to cook the
chicken than in a conventional oven, so it wasn't that slow a "slow cooker".


True.

A haybox works too. and our new wood burning stove is superb for
cooking.

How much of that was due to having better insulation than a conventional
oven?

The leads are part of the G5.3 lampholder, and come with PTFE
insulation on them in expectation they may get very hot.
I just cut them to the right length (so filament position is
about the same as in candle bulb which these are replacing),
and soldered to the lamp cap connections. The cables are
stranded but much stiffer than they look. They might be silver
plated to protect against copper oxidising, although the ptfe
is quite stiff.
