THX!!.....I'd still like to nail-down this width dimension!
After extensive web-searching I DID find this site with this info.

(Scroll down web page /link to see technical info.)
After finding this I decided to "risk it".
Ordered the strip on one site......the 4 -timers on another site.
Total cost was LESS than a dual-timer strip ("Coralife" or "Zilla" brand) for aquarium lighting that offered lighting cycle possibilities that I wanted.
Also reviews for those lighting strips were VERY poor overall.
With 4 separate timers,..ANY cycle is possible!
THX to all for responding...
I've been "agonizing" too long over this "minor" issue.
"Back in the day"....I just ran a standard tank light fixture with a upgraded color-bulb at best..
This 3 option fixture is a whole new thing.
