I'm curious about something guys. Energy saving compact fluorescent bulbs and fluorescent tube light fixtures don't work well at relatively low temperatures (below freezing) which is why they shouldn't be used in cold climates in an unheated garage.
Here's my question; how can fluorescent tube light fixtures in outdoor commercial signs work in cold temperatures? Are they designed different?

P.S.: Fluorescent bulbs can not be operated with the typical light fixture dimmer. I'm assuming that they require a specialized dimmer. And one last thought. I like the idea of saving money with energy saving compact fluorescent bulbs but I don't like the color of their light. What do you think?
