A bit OTT, but Morrisons sell 30W CFLs with a PF of close to unity. About
3-quiddish IIRC.

That's interesting. Is the PF figure a quoted one or the result of
measurements taken with a decent digital watt meter?

OK, just as long as you don't want to know the price!

Is the fact that a decent CFL 60W equivalent costs £54.99 not an
admission that those you can by for a pound or two are pretty crappy
compared with a good old incandescant bulb?

I have 60 and 100 watt lamps hanging about because I bought
lots years
ago and haven't used one for about 5 years! I can't find
anyone who
wants the blessed things now that CFLs and halogens are so
good, and
the cheap shops around here are still selling 4 x 60w for a
pound. My
father in law for instance is partially blind. For him it
means we can
use a 25 watt CFL in a shade rated for 60 watts of
incandescent lamp. A
huge increase in illumination for him, without scorching the
shades
which is what used to happen.

I would dearly love to find a CFL that was anywhere near
acceptable. I see
posts like yours and I do ask myself, what are these bulbs and
where do
they get them from. Every CFL I've ever seen has given off a
disgusting
greeny/yellow light with poor intensity nowhere near as bright
as a 60W
they are supposed to replace.

CFLs come in various wattages, from the 7 watt 'golfball' up to
23w. I
certainly find the Megaman golfballs and R50 (spots) as good as
their
tungsten equivalent. What are you using to replace a 60w
incandescent? If
an 11w CFL isn't bright enough, try a 15w one. The colour
temperature has
got much better over the last few years, too.

Some brands also come in two formats -- warm glow and harsh white.

And CFLs are so 20th Century now that LEDs have arrived.

sigh

OK then. Please give me name rank and serial number for an LED light
which
is a good replacement for a 60W bulb or was that sarcasm?

Many people seem quite happy with various types of new bulbs and I still
haven't seen even 1 with a decent amount of light output and a colour
that
isn't disgusting.

Why does the power factor matter to you?

Well, that LED one is dimmable (I know some CFLs are, I have a couple
they're buzzy and the colour temperature changes drasticly with
brightness) and supposedly it is genuinely as bright and warm as a 60W
incandescent.

However I really can't see them shifting many, seems they want to cover
all the R&D costs on the first boatload rather than over several years?
Whoever set the price needs their head examining.

Yes, that's the best part of my life wasted fixing TV aerials. It was
just after D Day that I went full time.

What should you have been wasting it on?

I should have

-- accepted an offer to travel India rigging comms aerials and taking
photographs for a motor rally

-- accepted various other offers (details not available)

-- taken an interest in IT before it was too late to take it all in

-- owned more dogs

-- spent more time with the kids when they were little

-- had more holidays

-- taken remedial action following my appalling education

Bob.

I don't think anything that just produces spot frequencies of light can
ever work properly. Our eyes expect continuous spectrum. There are bound
to be funny effects if you are looking at things under spot frequencies.
It's like watching television: the medium attempts to reproduce natural
colour but with a limited number of phosphors it can't do it very well.

It could be that I'm hypersensitive because an ancestor of mine actually
invented colour, in 1919. Of course it didn't catch on very quickly and
some people were still living in black and white in the 1960s. You can
see this on some early Beatles films.

Teaching English?

Ah well, things could have been so different! It was a close call, a
decision made almost by the toss of a coin. I've often wondered how life
would have panned out if I'd stayed in teaching.

Temperamentally though, I need to be self-employed.
