what is your favorite typeo of light?

I love thoes yellow sodium vapor lightes used in street lights but the best are the realy bright white lights used in football and baseball stadiums, I don't like football or baseball but I would go just for lights since they are sooo bright and it is like day but brighter and more white and it just being under the lights is like a shot of adrenaline.

[edit, I said mercury vapor when It was realy sodium vapor}
