Terminology: „Phase“: Power supply used to dim incandescent bulbs, halogen lamps, magnetic and electronic transformers for low voltage lamps „CRI“ (Color Rendering Index): It is the measure of how much a light source is able to make the colors of the objects it illuminates appear natural. „LM“ (Lumen): It is the unit of measurement of the luminous flux of a lamp, ie the quantity of light emitted. „W“ (Watts): Is a measure of power used as an international standard is used to indicate the power of an electrical product. „K“ (Kelvin): It is an international unit of measurement in which the color temperature is measured. The higher the Kelvin number, the „colder“ and brighter the light. The lower the Kelvin number, the „warmer“ and more yellow the light.
