Abstract
A beam for grid in a suspended ceiling that has an increased effective beam height over prior art beams. The beam has a peak at the top, which conforms to the shape of a standard light fixture box frame supported by the beam in the ceiling. The beam does not interfere with the proper support of the fixture frame on the beam flanges.
