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".

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

(I notice the current version on their websiteÂ* takes an LED bulb)

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.
