FilamentLogo Design Contest

Hi. I already prepared new vesion as you asked for, but problem is that only first 5 finalists from ranking can update the files in this fase.

Can we try something more like an Edison Bulb (vs. the sunburst/rounded look here)? https://media.restorationhardware.com/is/image/rhis/prod2680020?$l-pd1$

I do like the F as the base of the bulb.
