Abstract

In
this study the power, power factor, correlated color temperature (CCT), color
rendering index (CRI), lux values measured from 0.75 m distance, LED lamp
temperatures and changes in the currents of 6 LED lamps, which are most
commonly used and directly connected to the network are experientially
recorded. The effects seen from the very start and 1 hour later, on LED lamps
were compared in terms of temperature, current, and lux values. The high
temperature values on the LED were seen to have adverse effects on the
efficiency of the LED lamp.

Keywords

LED, lighting, CRI, CCT
