Abstract

A multifilament lamp combination (12 min or 121) is disclosed which may be used alone and in multilamp arrangements with other single and multifilaments lamps (12 min or 121) to provide pattern size variation from a large diameter flood effect to a smaller diameter spot effect. A spot/flood capability exists to provide large pattern exposure simultaneously with secondary spotlighting. The filaments (15 and 16; or 123, 124, and 125) can be energized selectively from a remote switching station (D) so that the individuals who are scrubbed and gloved need not touch any part of the switching arrangement (D) to change the lamp pattern size. A cluster of lights (111 through 113) can contain one or more is multifilament lamps (121) within the cluster, so that by switching on the rear most filament (123) of the multifilament lamps (121) and switching off the single filament lamp, a small high intensity pattern is obtained by switching to the other filaments, a large pattern of high intensity is formed. More than two filaments can be provided in each lamp (12 min or 121).
