This invention provides for an improved reflector-type lamp having reduced focus loss and exhibiting an increase in reflector collection efficiency. Stray light from the lamp's light source is reduced and channeled into the central angular region of the reflector where it can be more easily controlled and increase the in candle power of the lamp. A shorter, more compact filament design, wound with larger mandrel ratios, is positioned within the reflector to evenly disperse the light energy throughout the central angular region.
