Many tungsten were sold on ebay as `heaters`the wording got them around
the restrictions.

Which is probably a more accurate description of them, given most of

Same applies to LEDs, even the best are still only in the 30% to 40%
sort of area if you include the losses in the associated drivers etc.
Ulitimately of course *all* the energy ends up as heat.

Yeahbut, turn a 60W incandescent lamp on for 10 seconds and then try
and touch it. Have a 60W (light equiv) LED lamp on for 10 minutes and
it will still only feel warm?

Suggesting, that (light) like for like, LED's are generally much more
efficient as they generally run much cooler?

(I've got a 15W (equiv) desk lamp on here set up to the Home
Automation to come on when the light level drops below a certain
threshold and it's been on for a couple of hours now. Whilst it's
'warm' I can still easily unscrew it and take it out, not something
I'd try with even a 15W incandescent that had been on for a fraction
of that time). ;-(

Ulitimately of course *all* the energy ends up as heat.

What, even the stuff coming out as visible light / UV light?

And fluorescent tubes are reasonably efficient in terms of
light output vs power in. They give a much better light
for situations where you need to see fine detail.

Generally they're twice as efficient as fluorescent tubes. As this link
demonstrates:
https://en.wikipedia.org/wiki/Luminous_efficacy

The ballast also generally consumes a few watts.

Generally? Only one type. I know that when I've swapped fluos for LEDs
the latter haven't seemed much brighter, if at all.

LEDs should make the TV racks man's life easier. Not the same change in
colour temperature when dimmed. And give the AC a better chance of coping.

We tend to use Philips Hue for bedside lamps, and these can be set to
anything from cool shady daylight (probably about 10000 K) to very warm
tungsten (about 2000 K). I find that a sunlight temperature (about 4000-5000
K) is a good compromise. Supposedly warmer light than that is better for
reading in an evening, so as not to stimulate the body to produce melatonin
which can cause problems getting to sleep because the body sees it as
daylight rather than "time to feel sleepy".

In the kitchen and in my study, we use MiniSun GU10s which are about 6000K -
just slightly cooler than LED bulbs which are sold as "daylight".

I've not encountered any LED bulbs which have bad colour rendition, though I
bet if you looked at the spectrum of an LED bulb (whether warm, daylight or
cool) you'd find various absorption lines and emission lines, whereas
tungsten is a more continuous spectrum. Certain shades of red tend to be the
ones than look darker than they should under LED, by comparison with natural
sunlight.

I took a series of photos of a standard coloured test picture under a
variety of lights (fluorescent tube, daylight CFL bulb, tungsten,
warm/day/cool LED, sunlight, shady outdoors) with my camera white-balanced
from a sheet of white paper under each light. The results were pretty
similar, apart from a pillar-box red which came out a bit dark under LED and
much darker under fluorescent.

https://i.postimg.cc/W3d4Y1Hw/Led.jpg
https://i.postimg.cc/76jZFyv8/white-fluor.jpg

I'm not sure whether "daylight" (the first) was sunlight or shade, or what
colour the LED was - probably daylight coloured. The "white-fluor" is strip
light, and I presume it was cooler and not warm-white.

Note the different rendition of the red panel on the box of screws to the
left of the face.

I doubt LEDs will work in our John Lewis 'touch sensitive/three level'

FWIW I put a dimmable LED lamp in mums 'touch sensitive three level'
table lamp (and two similar used as bedside lights) and it/they worked
fine? I can't imagine it was bought with LED compatibility in mind but
it could have been LED compatible of course.

They might have been bought from Homebase FWIW.

I expect it's a single brightness lamp so no problems with dimming.

My ASDA three brightness lamp failed so I replaced the touch circuit
with an inline switch. Then I bought a replacement which was single
brightness and took LED. Had to as it can only switch 4W.

Very wise. Dimmers intended for incandescent lamps tend to be leading
edge. Even if it did work, I suspect the different non-linear
characteristics would mean that the LED lamp wouldn't dim nearly as much
as the halogen.

I'm sure halogen will still be available in its guises, but not from the
leading manufacturers, and so be of a somewhat variable quality.

Don't think reading is critical colour temperature wise. Unlike, say,
matching colours.

I've got a Lidl LED desk light where you can select warm normal or cool.

But how an LED appears, colour temperature wise, does not guarantee
continuous spectrum light as you tend to get with halogen.

Yes, this seems to be the case. Do you think price makes a difference

Low pressure sodium, yes. As that is very narrow spectrum. I'm surprised
any domestic light made much difference. Except, of course CFL, claiming
to be much brighter than they were. So if she substituted a claimed 60
watt equivalent, it was likely a lot dimmer.

Some of the LED lamps that come on and off automatically as driven
from my Home Assistant system seem to 'ramp the on brightness'
slightly (quickly) and much more visually down when turning off
(compared when turning them off at the wall) so that change in
functionality is probably because they are being used 'smart'?

When they are off at the wall they are completely off (electrically)
of course whereas when off from Home Assistant they are still powered
but are set to zero light output.

If you set them to come on via a remote of some sort you can gave them
come on at whatever level is appropriate (and that could vary
depending on the time of day) but still be turned up or down as
required (same remote).

Its trivially programmable to any rate you like with the Philips Hue system.

Philips did with the Hues. You are free to have any brightness you like as

with turn on and free to have it come on slowly like CFLs do too if you

senile arse, just like your idiotPhone, your Alexa and your Google Maps?

Apart from a few, rarely used, lamps that have yet to be changed, I have
long converted everything to LED.

Likewise. When we bought our house, the previous people had installed a grid
of GU10 fittings to light the kitchen and two of the bedrooms. The kitchen
had LED GU10s, although we replaced some of those with Philips Hue bulbs
that we already had, and moved the ordinary LED ones into one of the
bedrooms because both of those had tungsten GU10 - each bedroom used about
500 W (10x 50 W bulbs) so the saving by using LED instead was significant.

A few fittings were transformer-fed 12 V, so I converted those to normal
mains-fed because the mains LED GU10s are/were a lot cheaper than the 12 V
equivalents that fit in the same ceiling fitting.

The only rooms that aren't lit by LED now are an en-suite bathroom which
still has a grid of 12 V tungstens (I'd need to go into the loft and change
the fittings from there, because the lens on the front is glued to the ring
of the fitting and can only be changed from above) and the garage which is
lit by 5 ft fluorescent tubes. Oh, and a bedside light which is
touch-sensitive and can only be used with tungstens: my father-in-law, an
electrican, said that LEDs or CFLs would burn out the thyristor.

It seems a shame to throw away the perfectly serviceable tungsten bulbs, but
I can't see us ever using them, apart from the 60 W bayonet one for that
bedside lamp.


The real problem is light fittings which use various esoteric bulbs. Until
about 20 years ago, just about every light, whether pendant, batten, wall or
table lamp, used large bayonet. Then we started to get poncy light fittings
which used SES, SBC, LES - or LBC if you were lucky.

I know we are unusual in the UK in using LBC as the (former) standard, and
that even 220 V Europe uses LES (I'd thought that 240 V implied bayonet and
120 V implied Edison screw, but it's not as simple as that!). I still think
that bayonet is better than screw in terms of speed of changing (push, twist
slightly, remove) and in terms of not corroding into the fitting. It's a
shame that Philips Hue are not available in SBC - we've had to buy lots of
SES to SBC adaptors to rooms with SBC fittings where we want the
controllability of Hue. And the quality of the Edison screw part of those
converters is often very dodgy: we bought one batch where the act of
screwing in a bulb compressed the centre spring terminal in such as way that
it touched the screwed ring of the bulb as well as its centre contact -
bang! Those went straight back and I got Amazon to remove them from sale as
not fit for purpose.

Hmm.. I have about 25 twin 5' florries in my workshop in 4 switched
banks. This may be the moment to do the LED conversion.
