building a dimmer

[Andrei Butica]

good day or evening to everyboy

 

I want to build a dimmer for a car interior night shoot, I will use a convertor that will give me 1kw output from the cars battery at 220v ( I'm in Romania). My plan is that from the 220v plug of the convertor i go out into a household hardweare store dimmer and from the dimmer I go to the bulb( bulbs) that I have outside the car. I will use a cable with two wires.

For each bulb I have such a sistem, cabe-dimmer-bulb. My question is: Giving that I will shoot in winter, probably very humid and with a great chance of snow outside, is it safe to have a dimmer built like this? I'l make sure to isolate every conection and the bulbs themselves but is that enough, will I get burned?

 

so, simplified: two wires come out of the convertor (220v/AC), enter into the dimmer,than go out to the bulb. is it safe?
