Dimmer?

[snakesRkewl]

Hi,

I'm going to menards or lowes to pick up a dimmer for my rack. Does anyone know what make or model I should get? I don't even know what one looks like?
I will be getting a rheostat soon, But I will have to use a dimmer for now, Preferably a cheap one.

If anyone has any pics or info on this that would be great.

Thanks in advance,
Jeremiah

You do know that dimmers and rheostats won't hold the temperature stable if the temperature in the room goes up and down.
This is why most of us use thermostats instead
