The manufacturer might make the bulb for exterior settings with features like pre-start heating or a shorter arc length, but you'll need to find the bulb specification to determine if the lamp will start in the setting you're planning on. Generally speaking, freezing is pushing it for most fluorescent bulbs, but there are bulbs that can get down to the -20 F range.<br /><br />And no, Dave, it doesn't make a whole lot of sense to toss the ballast when the lamp is changed. However, ballasted CFLs probably make up the cost of the ballast in energy savings if they're replacing an incandescent bulb. If you really want to be efficient, get dedicated fluorescent fixtures that use T5 HO bulbs... from the information I've compiled, these give off the most lumens/watt with the least waste material. Keep an eye on solid state lighting such as LEDs, though; their price continues to drop and the efficiency and quality keep climbing as research continues. The lifespan of LEDs is already exceedingly high where light fixtures are concerned, and there isn't the mercury waste issue encountered with fluorescent bulbs.

The ballast adds to the overall length of the lamp, limiting the fixtures it can be used in and limiting the design flexibility of the fixture designers.

What is the mean lumens rating for the lamp?
