The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.
Select the wattage of your conventional bulb to find the LED equivalent.
Unified Glare Rating
The Unified Glare Rating indicates the amount of blinding glare emitted by a light and, therefore, its potential to cause visual comfort. In offices the UGR rating should be <19, while in public areas <22 is sufficient.
