between straight fluorescent lamps for general purposes and straight
fluorescent lamps for special industrial purposes. Only the first type of straight

Manufacturers/importers
Manufacturers and importers (such as Philips, 2009; Osram, 2009;
Megaman, 2009) often divide compact fluorescent lamps in general types
according to:
� Function, such as dimmed, night lamp, outdoor;
� Shape, such as pear, globe, candle, spiral (See Figure 2-2 for
examples);
� With/without integral ballast.
Danish energy saving trust
The Danish energy saving trust also divides compact fluorescent lamps
according to shape (pear, rod, other) (Elsparefonden, 2009). See Figure 2-2.
