This study was conducted to compare the different light sources (Incandescent lamp, fluorescent and marcury vapor), lighting periods (16 and 17 hours) and methods (Continuous and intermittent) on protuction traits, feed consumption and egg qual-ity. In addition treatments were compared for net befeit. Localy bred hybrids G 92 xS 92 were used in this study. There were statistical differences among the treatments for the age at first egg, 50% production age and live weight at 50% pro-duction age and at 72 nd week (P
