Do you supplied drivers fit through the cut out hole for the fittings they are supplied with?Yes, all of our Office LED downlights are supplied with drivers that fit through the cutout hole so you do not need to access above the LED Downlight to fit the driver.2. What’s the difference between CRI and CCT?Usually, there are two key measures used to valuate lighting sources:  Color redering Index(CRI)  Correlated Color Temperature (CCT)  CCT Measures the color of a light source by using Kelvin (K) temperature,  Color rendering Index (CRI) helps match human perception of color quality.
