What does 'warm white' mean?

Warm white is a color temperature of 3000K. This means it will have a more traditional yellowish color, similar to an incandescent bulb. If you want a more modern, cool white appearance, choose the 6000K option.

Is this bulb polarity sensitive?

No, this bulb is not polarity sensitive. It will work in either direction. If the bulb does not light up when you first install it, try flipping it around.
