Spotlights

[csehz]

Hi, can you please advise about how to do spotlights?

Actually I am aware of two methods, on the attached picture left side creating a high step blend between two ellipse with changing profile, or maybe creating two rectangles over each other with linear transparency and changing the amount of feather for both.

Probably the blend is the best but the high blend steps typically requires a lot of resources on my computer. Are there maybe methods help on that, for example creating bitmap copy, however that I do not like too much
