Lighting Fixtures
When a round metric 600 by 600 or 600 by 1 200 ceiling grid is installed, round metric lay-in
type fixture sizes must match. Many fixture manufacturers currently produce or can produce
both modular metric sizes and still utilize currently used standard bulb sizes. When other than a
lay-in type of lighting fixture is used in a project, then size is not critical and can be specified
as an approximate size as in other equipment. The following companies produce both 600 by
600 and 600 by 1 200 fixtures unless otherwise noted.
American Fluorescent, IL, supplies fixtures in orders of at least 500 fixtures (Gary
