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?
