Some of ours do.  Every Sun I have ever seen (of those that have
graphics screens, of course) has a brightness control of some sort; in
some cases it is just a bare potentiometer shaft, in others it is a pot
shaft with a knob on it, and on yet others it is a thumbwheel sort of
thing - sort of like a knob of which only one side is accessible.  But
every single Sun monitor I've ever seen has a brightness control
somewhere, and some of them even have a knob on it.

Perhaps there are some that don't.  I haven't seen an example of every
type of Sun in existence.  But I am familiar with the -3/50 (mono),
-3/60 (mono), -3/60 (color), -3/160 (mono), SLC (mono), SS1+ (mono),
SS1+ (color), and have used a -4/110 (mono).  Every one of them has/had
a brightness control.

I restrict myself to those with graphics screens because you say
"workstations".  But you bring up a good point; I have seen dumb-ascii
terminals that hide their brightness control faily effectively, though
I can't recall having seen one utterly without such a control.
