fluorescent lights that can operate outdoors at cold temperatures.
fluorescent lamps are not suitable for outdoor applications. At cold
temperatures (below 4°C or 40°F), the ballast (in particular, magnetic
ballasts) may not be able to start the lamp.
Most cold-temperature compact fluorescent lamps with electronic
ballasts can operate properly down to -29°C (-20°F) provided they are
installed in an enclosed fixture. Below this temperature, the lamp may
still operate but the light will flicker and have reduced lifetime. The
light output is reduced at cold temperatures. However, if the lamp is in
an enclosed fixture, the heat from the lamp will warm the fixture and the
light output will rise to normal levels.
Normal compact fluorescent lamps are limited in size to 26W and 1800
lumens; long tube lamps with higher output are available although they may
be difficult to install in an enclosed fixture. Compact fluorescents have
a rated life of 10,000 hours.

compact fluorescent lighting is best used for accent, walkway or low-level
security lighting. One type of security lighting combines a compact
fluorescent lamp with a motion sensor. Compact fluorescent lamps are not
suitable for high outdoor lighting requirements such as parking lots.
Low-pressure sodium lamps or high-intensity discharge lamps should be used
in these applications.
fluorescent lamps operate well in cold climates (under the conditions
noted previously). In some cases, the rated lifetime has not been
achieved; this may be due to constant cycling (on-off) of the
The cost of a 26W compact fluorescent lamp (with
ballast) is approximately C$30. The price for enclosed fixtures will vary
with the type and style chosen.
