LEDs have about half the running cost, AFAIR. And seem to last longer.

You may prefer to keep a few CFLs in positions that get turned when the user's eyes are dark-adapted, as they turn on more gently - but you should know that already.

The best leds like Hues can be programmed to turn on at any rate you like.

Off too.

That's generally regarded as an annoyance. If you want them to come on
gently, use a dimmer (if the lamp type will tolerate them).

Also some do not like the suddencut off in lighting area of leds, but they
are , apparently getting better in this respect now.

My one concern has been that some LEDs have some kind of switch mode psu in
them and kick out rfi at an alarming rate, but I'm sure these are mostly the
el cheapo ones.
Obvioulsly myself I hardly use lights these days, but as long as you get
the right colour temp for what you need then I think LEDs are more
efficient, and come on faster.

Well, actually they come on at full bright instantly. That alone saves
current, because I feel more inclined to turn them off, knowing there
will be no delay when I switch them back on.

I just bought a couple from B&Q (yes, I know, but I needed them _THEN_
to go with some new lights).

Much to my surprise they take a second to come on. And are completely
flicker free.

Not my experience, albeit with a niche product. I bought MR16 (12
Volt) spotlights and the radio frequency interference was so bad it
obliterated DAB reception in my kitchen. I returned them, they denied
receipt, I scanned and emailed the proof of delivery, they said the
person who signed was not an employee and the words delivered from
named sorting office meant the package was still at the sorting
office. Eventually they conceded the package was in their office
after all.

I have bought quite a few from LEDHut, and found them to be pretty good.
I have had a couple of early lamp failures. In each occasion, I have
emailed them and they sent a replacement FOC without quibbling, or even
requesting the dud ones back. I found the filament style 60W equiv lamps
to be very good a true match for light output and a pretty good CRI.

Yes, that's pretty much what we've been doing, but some cfls are being
replaced when they start being annoyingly dim, rather than when they're
totally dead.

I prefer CFLs because there is less flicker if your eyes rapidly move across
the light. I have a Philips Hue LED bulb and I am very slightly aware of
multiple images, in different colours, of the bulb if I am looking at
something on one side of the bulb and then look to something on the other
side. I wonder if the various LEDs that make up the white light are pulsed
in sequence rather than all being fired simultaneously although with
different mark:space ratios to get the desired colour balance.

Also, can you get an LED bulb yet that is as bright as a 25 W CFL which is I
think is equivalent to about 150 W tungsten?

The other thing: LED GU10 spotlight bulbs have a very narrow beam with
sharply-defined edge, whereas tungsten GU10s are wider and the cutoff is
more gradual. If you have arranged tungsten spotlights to give fairly even
coverage, you may find dark patches in between if you switch to LED. I'm not
sure whether there are CFL GU10s.

Not all LED GU10s have narrow beams - mine cast a similar beam to
the previous halogens, which were wide beam (can't recall exact
angle but remember going for widest available!). You are right
though, it pays to be careful when selecting them.

But probably not at 2700K.

You need to be looking at 15W for that.

It's interesting to use one in a common situation - say a central pendant
fitting in a white or light coloured room, and compare the ambient light
between them. My guess is they have a very special tungsten 100w they used

I have found that these:

https://www.ledhut.co.uk/led-filamen...hape-bulb.html

Seem to compare well to a 60W GLS - similar pattern of light production,
colour temperature, and brightness. CRI is not far off.

Note tried this, but:

https://www.ledhut.co.uk/led-filamen...00k-clear.html

Claims 1440 lumens which is in the ball park for a 100W (perhaps closer
to a 90W)

I've heard that the claimed lumen output from LED bulbs is often
overstated.

Apparently there is an acceptable tolerance in stated lumens to
account for the variation inherent in tungsten bulb manufacture. But
LED bulbs can be manufactured to a more precise light output, so
manufacturers can claim a higher lumen value while ensuring that the
bulbs will fall within the acceptable range.

I've also heard that some claims used to be based on the output from
the LED chip rather than the entire bulb. I'm not sure if this still
goes on, or whether it's been banned.

ISTR the comparison was against a pearl 100W lamp - and then probably a
240V one running at 230V just to help manipulate the figures:-)

BTW I put a lightmeter app onto my phone the other day and compared it
to the proper lightmeter we use at work.

It was surprisingly accurate.

Getting rid of the heat may be the killer for LED bulbs in a small
package that's why its worth considering changing the light fitting to
something like a round panel light which commonly come in 12W, 18W or
24W varieties. The LEDs in these are the flexible LED strips but
attached directly to the body of the light fitting to act as a heat sink.

Most certainly true of G9 bulbs, which are much dimmer than the halogens
they replace. The fittings for G9s are usually pretty small, and heat
build-up is a real problem.

I'd get some in ready and try them out before the CFL blow, you might not like the 'cold' colour ones so get a 'warm' one too . You could try mixing them that might help you get used to the differtn colour temperature and the mostly spotlight effect you tend to get with LED bulbs.

Yep.

Pros and cons?

Its obviously going to cost a bit to change them
rather than wait till the cfls fail one by one.

One advantage is that you can get leds that
you can change the color temp of with a switch
which cant be useful in some situations. And the
good ones last longer and are easy to do in led
strips. cfls are more concentrated light.

Pros..
They come on instantly to full output, last considerably longer,
cheaper to run.

Cons..
None really, though some complain about the light spectrum.

I converted all of my regularly used/regularly on lights, over to LED
12 months ago - not a single failure so far. They vary from 3w to 9w.
Just to be clear, I did only swap out the ones which we use often - I
didn't do centre lights and some were 22w CFL's.

I've completely swapped to LED over the last two years and no failures
yet. I took the opportunity of fitting (surface mount) LED panel lights
in the bathroom, kitchen and hallway which I've found give a nice even
spread of light.


As for the colour temperature of the LEDs its really down to personal
preference and you have to ignore those on here who preach that those
horrendous warm yellow bulbs of yesteryear are more natural because they
are the same colour as the candle chandelier they replaced You may
find that for close up working or reading if you are of a certain age
and/or don't have perfect eyesight then a colder blue or daylight type
temperature LED suits you better. Buy a couple different temperatures
LEDs and try them out. Relegate the bulbs you don't like to somewhere
that is used infrequently.

In the past two years, I've had two LED GU10 spotlights fail. They are
mounted in a modern 5-spotlight strip that is also two years old (so it may
have been made with LEDs in mind - or it may not). The symptom is pronounced
flicker, then the bulb goes out or fails to come on when the main switch is
next turned on but does come on if the switch is cycled off/on.

LED bulbs are very fussy about the ventilation of the light fitting (the
cylindrical shank of the bulb). The light-emitting part of an LED bulb
barely gets warm but even a 7W one gets almost too hot to touch close to the
fitting.

I swapped some 100w 100mm ES floods for 9w LED's in the kitchen, backed
up with a hidden 6' fluorescent for additional light as needed. Those
9w wide angle flood lamps barely get warm when on and have been in use
for 12 months now. I would get concerned about the life of any LED
getting near to too hot to touch.

Pros..
They come on instantly to full output, last considerably longer, cheaper
to run.

Cons..
None really, though some complain about the light spectrum.



I've completely swapped to LED over the last two years and no failures
yet. I took the opportunity of fitting (surface mount) LED panel lights
in the bathroom, kitchen and hallway which I've found give a nice even
spread of light.


As for the colour temperature of the LEDs its really down to personal
preference and you have to ignore those on here who preach that those
horrendous warm yellow bulbs of yesteryear are more natural because they
are the same colour as the candle chandelier they replaced You may
find that for close up working or reading if you are of a certain age
and/or don't have perfect eyesight then a colder blue or daylight type
temperature LED suits you better. Buy a couple different temperatures
LEDs and try them out. Relegate the bulbs you don't like to somewhere
that is used infrequently.

That's why you have to go online and stop bother with high street shop
which often sell utter junk.

Or buy the fancy leds that can be set to any color temp you like via
the app so you can have a different color temp when doing fine
work or reading and when doing other stuff like ****ing the slut etc.

I converted all of my regularly used/regularly on lights, over to LED 12
months ago - not a single failure so far. They vary from 3w to 9w. Just
to be clear, I did only swap out the ones which we use often - I didn't
do centre lights and some were 22w CFL's.


I went nearly all LED a few years ago (I cannot find an LED light that
would be a good replacement for my outside floodlight). Swapped the gf's
lamps about a year later.

Not one failure.

However I have fitted thousands of them and I do see failures - usually
in the the first week or so. But not that many.
