		Reflector lamps (Type R) are designed to spread light over specific areas.
		The ellipsoidal reflector (Type ER) focuses the light beam about 2 inches (5 centimeters) in front of its enclosure and is designed to project light down from recessed fixtures.
		Ellipsoidal reflectors are twice as energy efficient as parabolic reflectors for recessed fixtures.

		A white, sharply-outlined, 200' ellipsoidal object was reported and listed in the Blue Book Unknowns.(McDonald) A midday sighting by a University of New Mexico meteoriticist, Dr. Lincoln La Paz, and members of his family was summarized by _Life_ magazine years ago without identifying La Paz's name.
		The object was described as ellipsoidal, whitish, and having sharply-outlined edges.
		Markley while watching 2 balloons with radar reflector to the SE in 10x binoculars saw traveling at unprecedented rate of speed around white object in horizontal flight S to N several thousand feet over the tops of Sacramento Mtns.

	UFO Symposium 1968: Baker Statement
		Examination of film frames obtained from the photogrammetric experiment -- reference Analysis of Photographic Material, Serial 01, Appendix II -- show that no significant broadening is produced by flat white diffuse reflectors such as birds, bits of paper, etc. at f/16 under the conditions of the filming.
		The actual exposed white area of a bird is usually less and depends upon the perspective of the observer.
		This difference has been roughly accounted for in the data given, however, if the body were the principal reflector the distance given should be reduced by a factor of 2 or 3.

	SBF Glossary: ER to Es war einmal
		In the strict sense of the term that excludes ER lamp, an R lamp has a bulb with a parabolic reflecting back surface.
		As the name implies, however, an ER lamp has an ellipsoidal reflecting surface.
		The filament is placed at the nearer focus of the ellipsoid.
