One thing that I'm always surprised at with LED bulbs used as room lights
is how bright the dimmest setting is - it's probably too bright to use as
a night light so you can see your way to the loo at night without the
light keeping you awake as you try to get to sleep.

Thats not true of the Hue bulbs.

Actually I have seen this with Hue bulbs - both the fixed-colour and the
colour bulbs. I suppose it's a matter of personal preference how dim you
like the dimmest setting to be, but the dimmest that I have seen with Hue is
still fairly bright.

Given that LEDs are usually dimmed by altering the mark:space ratio of a
constant-frequency square wave, so the light is turned on for a
progressively shorter proportion of each cycler,

Thats not true of all dimmers.

Ah, do some of them simply reduce the current, as you would with tungsten -
though with more complicated electronics?
