Bright Tighting

(Cantinued, lrom Pa.ge 66)

The reason you get a loss in contrast is quite simple, Professor Grifrth explains. For example, in the pencil task, paper reflects more of the diffuse or uniform light than the pencil mark reflects. This difference in brightness is the contrast which allows a person to see the writing on the Paper.

In his tests, Professor Griffith used a onetwelfth scale model room 30 feet by 30 feet with a l0-foot ceiling. He simulated lighting conditions, since it was difficult to obtain ideal test conditions with a full size room. The model's window wall was 30 feet long by 6 Leet 9 inches high from a 42-inch sill.

In summarizing the results of his test, Professor Griffith said the gain in task contrasts wherr sidewall lighting is used would indicate "the need for changing illumination recommendations to specify different levels depending on the lor:ation of the major source."

For good vision it doesn't matter whether the sidewall lighting comes over the left or right shoulder. Either provides good illumination for readins"

Poll Vetoes Numbers

By a vote of nearly two to one retail lumber and building material dealers have gone on record as preferring the use of numbers rather than names in the grading of lumber, according to a poll by the National Lumber and Building Materials Dealers Association at the request of the National Lumber Manufacturers Association.

The great majority of dealers responfing to the poll said they felt mrmbered grades would mean more to customers and result in less confusion.
