This model was carried over from the previous range, but had an improved projector casting with screw controlled elevation. Although the projector was the same as that used on the "standard searchlight", this model gave a more powerful light because it had a more powerful bulb and a 4.5 volt battery. The round base searchlight was in production for longer than any other model and as a consequence is the most common Astra toy found today. The Astra-Pharos Round Base Searchlight is Number Model Number 15 in the range.
