Why is it that table and desk lamps are so badly designed nowadays, I

I bought a bedside lamp only a few years ago. All I have to do
to turn it on or off is to touch the metal shaft or base.

I would quite like to buy a floor standing reading light for my wife but
I have yet to find a suitable one, especially as I want one where I can
change the bulb.Â* These days some lamps are made with LEDs where you
would have to scrap the lamp if they fail.


LEDs in conventional light fittings are more likely to fail because the
LED or the electronics are squashed into such a small space with little
heat-sinking. Heat kills LEDS and the associated electronics.

I have floor standing LED reading lamps where the illuminated area is
16cm x 10cm and the fitting runs at around ambient room temperature.
They are around two years old already and I expect them to last for many
more years.

I don't worry too much about replacing fitting when they expire and most
of my ceiling lights are LED panels of various types.
