I had some LED filaments left over from my big open filament lamp project, so I spontaneously decided to make a tubular LED filament lamp after discovering that test-tubes fit nicely into salvaged lamp bases.
Initially I was tempted to cheat with the absolute minimum number of components by using a single diode instead of a bridge rectifier, using a single current limiting resistor and omitting the capacitors discharge resistor, but then I decided to do it with a full circuit. This was a good approach because the circuitry is visible inside the glass tube and looks good.
