Due to the global interest of Light Emitting Diode (LED) Technology, LED lamps manufacturers and academic researchers are doing great efforts to study different aspects of LED lamps performance. This paper investigates the photometric and electrical properties of LED lamps. The effect of temperature on the output light emitted from the LED lamps has been studied and a model of LED lamp is simulated and presented in this manuscript. The presented model has been implemented experimentally to investigate the lamp performance. Experimental results show that the effect of aging test on photometric parameters of LED lamp such as luminous flux, correlated color temperature (CCT), color rendering index (Ra). This study enables to understand and well control the features of the visible light emitted from LED lamps. The value of CCT is an important parameter in many applications such as lighting, videography, photography, publishing, horticulture, and manufacturing. It is desirable to achieve a high CRI light in color-critical applications such as neonatal care in hospitals). Experimental results also demonstrate that PF of LED lamp driver decrease when the lamp is operated in high ambient temperature.
