The specialty lamp group is a combination of various lamp categories with different applications. The colored incandescent lamps are available for both indoor and outdoor effect lighting. These lamps are used for creating special events as well as highlighting the architectural features of residential and commercial properties. The double contact B22D base lamps enable the simple conversion of European fixtures to North American power supplies without the necessity of converting all of the lamp sockets to E26 medium screw base. Aquarium fluorescent lamps are uniquely designed for both freshwater and saltwater aquariums with the ideal light spectrums for coral and plant growth as well as providing full spectrum light to enhance the colors of all the aquarium inhabitants. Finally, half-chrome lamps are designed to be used in fixtures that require inverted lamp installation and would produce a significant amount of environmental glare without the use of the chrome shield inside the lamp to create a soft indirect illumination pattern.
