Making a huge open filament lamp with a load of the LED filaments just seemed a logical thing to do. So here it is.
It uses a smoothed resistive dropper to run two circuits of four series LED filaments at just a couple of milliamps each to give the effect of a huge tungsten filament on support wires.
The circuitry is potted into a base from another LED lamp and has three solid core insulated wires (stripped from house wiring cable) which provide support, a common negative connection and two current limited positive connections to the zig-zagged filaments.
It should be noted that the solder connections on the filaments are live at nearly 300V DC and capable of giving a zing if touched.
Even at just a couple of milliamps, the light output is surprising.
