Each lamp unit comprises a formed glass reflector and a tungsten-halogen lamp located within the reflector and having a planar, dual filament structure therein. The lamp units are positioned within the holder such that the planes occupied by the respective dual filament structures intersect at a predetermined angle, e. g. 90 to 110 degrees, in order that the light output from each unit will be centered on a respective diagonal of the rectangular subject field being illuminated by the movie light. Each unit produces a bimodal intensity distribution, thus further assuring increased. illumination levels on the subject field. An incandescent lamp unit suitable for use in the movie light is also disclosed.
