Thank you everybody for your comments, e-mails, and
personal experience with battery operated OTT lights.
Now, I'm looking at this model.
Ott Model #290089.
It is light weight.
When it is closed - it is about 8" high + the base
(says on package) is 2 1/2 inches.
It uses Double A batteries (Four AA Batteries)
Compatible with a 6V adapter (not in the package w/light).
Right now, they are 40% off at Michael's
+ that would be about $29.00.
I am guessing that four AA batteries would last
longer than three AAA batteries --- but, I'm not sure.
