I need the inductance value of a 40Wbulb

Why do you need to know this? The inductance is insignificant for normal 50 or 60 Hz operation.

Note to others: a light bulb filament is a coiled wire, obviously there is some inductance there.

Which 40W electric bulb? You could calculate it or you could measure it. For a traditional household incandescent bulb, the equivalent circuit would be an extremely low inductance in parallel with a resistance (when lighted) of about .003 ohms. But as I'm sure you know, you didn't provide enough information to answer your question.

The light bulb of 40 Watts has no inductance to be considered at 60 Hz.

Inductance should be negliable in a light bulb. A light bulb essentially consists of a resistive filament between two electrodes, therefore there is no real source of inductance.

incandecent lamp is considered a totally resistive load (of negligible inductance)

That is a non sense question. It like asking what's the take off speed of a Honda.
