Using a sample of 29 bipolar Planetary Nebulae (BPNe) we show correlations between the luminosity and SED shape with the inclination to the line of sight of the objects polar axes. The presence of an equatorial “doughnut” of material around the central object can explain both these correlations and also and the bipolar shape.
