2H Choke 600mA of EI steel core use for tube filament supply calculation

[supernut]

To wind 2H Choke 600mA on 70 mm EI steel core with diameter of 14mm of left and right and 28mm center, thickness 40 mm (as picture)

Voltage input of coil is about 18 VDC.

Question.
1. Copper Wire number for 600mA 18V? #18 1mm suffice?

2. Number of turns

Thank you very much.

Ok just get the value thank you very much

As a comparison, in countries with 240Vac mains a classic 18W flourescent light used a choke/ballast of about 1.7H with a dc current capability of about 400mA and circa 50 ohm DCR - they are also designed for high AC voltage application (as in choke input filtering) due to their original application. They use a very optimised core and winding due to the mass market at the time, and that achieves a notably high self-resonant frequency of about 10-14kHz, along with throw-away pricing for 2nd hand items.
