First time I combined focus bracketing/stacking and HDR. I needed HDR obviously to deal with the brightness levels. At the same time, I wanted to have the bulb interiour completely sharp, but the background should be as blurry as possible. So I had to open the aperture to F2.8 and shoot 15 shots (stepping 1). I did 5 brackets with 2EV difference. Post processing was to stack the 5 brackets (Helicon Focus method C) and then merge the HDR in Lightroom. Some global and local adjustments in LR as well.
