2103358 9301613 PCTABS00019 An improved incandescent lamp is disclosed that is specially adapted for use in combination with a concave reflector (15) in providing a high-intensity beam of light. The lamp (13) includes a plurality of linear, helically-wound filaments (25a, 25b, 25c, 25d) arranged with their longitudinal axes parallel with each other and spaced substantially uniformly around the lamp's central longitudinal axis (29). Orienting such a lamp with its longitudinal axis aligned with the reflector's longitudinal axis, and with the filaments near the reflector's general focal point, ensures that a high proportion of the emitted light is collected by the reflector (15) to project the high-intensity beam.
