We have a number of those "bedside lights" with a transformer in the
base and a pair of "radio aeriels" taking 12 volts AC to the light unit
containing a 20 watt halogen G4.

I've just used my last spare halogen bulb, I see there are loads of LED
replacements around.

For main domestic lights I have long since replaced halogens with LED
but I am not so bothered about energy saving or safety for bedside
lights, and I do find halogens give good light for reading.

Are LEDs OK in this type of light, or would you stick with halogens?
Presumably the crude power supplies work fine with LED?

TIA

For a reading light I reckon LEDs should be fine. I am always a bit
nervous of quartz halogen lights in close proximity to paper.

I think the problem with the type of light you have could be the
physical size of the LED "bulb" compared to the halogen. From memory of
having similar light in the past was that the halogen just fitted.
However with lED running a lot cooler the glass cover could be discarded
giving more space.

+1

(just be a bit careful you can get 1.8W (~20w Halogen) and 1.0W (~10W
halogen) I can only speak for the 1.8W which seem to be fine. I expect
as always you need to make sure that you get the colour temperature that
you prefer - presumably warm white for bedside.

Thanks everyone for the comments, I'll give LEDs a try. (I actually
quite like the blue-ish halogen light for reading).

I fitted a couple of G4 LEDs in a Cooker Hood. They flicker a bit - I
suspect they are under-loading the power supply.

or maybe a cooler/blue white for reading. I find with my ageing eyes
that the blue white light gives better contrast when reading from a book.

Thanks everyone for the comments, I'll give LEDs a try. (I actually quite
like the blue-ish halogen light for reading).

I like a reading light to be behind my shoulder, illuminating the page
mainly and leaving the rest of the room darker to avoid distraction.

I used to have a fluorescent tube desk lamp on an Anglepoise-type arm. This
was good but I was conscious of the mains-frequency flicker when I first got
it.

I now have a lamp with a shade on a bedside table, using a Philips Hue bulb.
This is a nice restful light, and can be dimmed and altered in colour
between very warm (candle-light) and very cool (daylight in the shade). But
it's not as easy to get good lighting on the book, without my body getting
between the light and the pages. I need to find a *cheap* Anglepoise-type
desk lamp. The one I've got on my desk in my study is probably overkill
(expensive and a very large head) but I'm sure smaller ones are available
now as bedside reading lights.

Even halogens are on the warm end of the range of LED light colour
temperatures, and you will find the daylight white LEDs a great deal
bluer. I find this best for reading too.

Yes, I have a fitting with 6x 12v G4 20w halogen lamps.
It would not even light up with 6 x 4W led lamps in it.
Basic, wound, transformers will be fine, as they always give out power, a
lot of the solid state ones cannot detect the low wattage required by LED
lamps, so do not work.

Halogens are towards the red end of the spectrum. If you want blue, get
any cheap LED. ;-)

I have given up on physical books completely now and only read ebooks
and that fixes the lighting problem completely and can be done anywhere,

Yes they got very hot. I had one with what looked like a car headlight bulb
in it and the outside could burn you if you left it on for a long period.
