    I have a UV lamp i want to power using AC 120 volt wall outlet. I believe from the specs pasted below i need to build a circuit for 99 volts and .355 amps, 30 watts. I know how to do this using DC, but not using AC cause of hertz required. Im using 24 gage copper wire.

    How many feet of wire does this circuit need to be in order to meet the power requirements to power the bulb, 30/35 watts? AC.

    here is the uv bulb specs that i need to build a circuit for.
    G30T8 - 30 Watt T8 Clear Germicidal Fluorescent Lamp G13 Base 99 Volt .355 Amp 35.16" Maximum Overall Length, 8,000 Average Rated Hours. Spectral UV 253.7NM

    i dont have the money for a ballast. i have to used the 24 gage wire i currently have.

    how many feet of 24g cable required to power this bulb?

    This is an arc lamp. It doesn't use resistance, it uses inductance to limit its current.
    How many feet of 24 gauge wire does it take to make .95 Henries?
    It depends on the shape and the core material which you have not provided in your post.

    Feet does not matter. You don't use wire alone. If you can't get a proper ballast, then you don't have a path to success.

    i thought i could just build a circuit rated at around 35 watts power and it would power up?

    Would DC power this UV light bulb??? or is it designed for AC only?

    Inches might work.
