Would this solve the

no

Would it solve the problem if I used a different type of device rather
that switched mode?


Device? I don't know what you mean. Maybe unsnip some.


If you followed the rest of the thread, you would have seen the link

I was thinking of what is described there as a linear power supply.


Unfortunately you have used a phrase here that also has a distinct
engineering meaning namely a previous power supply technology that used
to work by having a big chunk of iron transformer rectifying it and then
having a voltage regulator that dissipated the excess unwanted voltage
as heat to leave a nice smooth output at high current.

Switched mode PSU is the exact antithesis of linear PSU. Being highly
efficient at turning low current high voltage into high current low
voltage with a minimum of weight and heat.

In addition because LED devices are current driven the PSU used with
them is by a regulated current source rather than a voltage.

Halogen is just a crap option for indoors. Some people love them of course, but then some people drive Trabants.

Very insightful. It's for the kitchen not the toilet though.

What lighting would you actually recommend for a kitchen and for what
reasons?


I find a mixture of LED and LED spotlamps in classic spotlamp fixtures
works OK. The design allows enough airflow to allow them to stay cool.
