LED bulbs oﬀer light in a range of color temperatures, it’s what makes light feel ‘warm’ or ‘cool’. A lower color temperature produces a warmer, more relaxing light. A higher color temperature emits a cooler, more refreshing light. Color temperature is measured by Kelvin (K) and can be found on the packaging or in the light bulb’s speciﬁcations. If you’re looking for a new bulb that is the same “color”, choose light with the same color temperature. Some bulbs like SceneSwitch oﬀer multiple color temperatures in one bulb.
