The development of light sources that provides lighting with electrical energy has a history of about 200 years and it has still
been continuing today. Over the time, diferent light sources have been developed by the use of diferent technologies. Eventually, a large product inventory comprised from light sources in diferent structures and characteristics has been obtained.
Residential lighting is an important feld in the sector in terms of appealing large number of users and a wide range of application areas. In addition, lighting quality is prioritized in residential buildings, because people get more closely exposed to
artifcial light in those places. In this study, the most commonly used eight diferent light sources in residential buildings have
been investigated. The selected light sources are comprised of the products from halogen, CFL and LED lighting technologies.
All the light sources have been chosen with equivalent luminous fux values. The selected light sources have been subjected
to photometric and electrical measurements realized simultaneously under the same ambient conditions. The interactions
between photometric parameters and the meaning of these magnitudes in terms of users have been tried to be explained in
an explanatory language. For the same purpose, electrical parameters have been also examined and their meanings terms of
both the user and system have been given. Based on the results obtained, evaluation of the light sources selected from diferent technologies have been provided sophisticatedly and their suitability in terms of users and systems have been discussed.
In the last part, the loading efcacy value has been examined and reference has been made to the appropriateness of the use
of this value in expressing the efciency of the light sources.
