My wife prefers uniform lighting - even if that means you are looking
into the light. When reading in bed, she will turn on the overhead light
(single ceiling rose or lots of GU10 spotlights) which illuminate the
rest of the room and shine right in your face, but leave the pages of
the book in shadow, She believes that reading by over-the-shoulder
light, with the book brighter than the background, strains your eyes.


Over-the-shoulder light would be a lot better than black letters on a
very dark gray background (because your eyes are adapted to the bright
light coming around the edges of the book).

It's rather obvious now, a troll-feeding senile idiot is as much of a
driveling mentally deficient idiot as the troll he keeps feeding!

I have a LED

That irritates me, why don't you write "an LED"? How do you say
"LED"? I say "Ell Eee Dee", not "Light Emitting Diode". So it needs
an "an", not an "a".

"an LED" irritates me. I know the word is "light".

It's "a LED" if you pronounce it as an acronym.

What do you mean by "pronounce it as an acronym"? I would have said
that means "ell eee dee" as in you're treating it as an acronym rather
than a word and spelling it out.

An acronym is a pronounceable abbreviation, e.g. NATO, scuba, radar.


Ah, I always say acronym to mean abbreviation. I don't care if it's technically wrong Smile

More light is better if the whole room is lit evenly. Which is why I
prefer strip lights to point sources. Much better if you're soldering
for example, you don't create shadows, as light can come to the
workpiece from all angles, no matter where your body/head/hands/tools are.

In the case I described, the lamp (a "helpful" person tuned on) was to
my side, almost the same direction as the back of the TV.


The lighting in all my rooms comes from striplights all over the ceiling, so everything is lit nice and evenly.

no it isn't and your light is a bare bulb in a night light
