LEDs with this light color contain a significant amount of blue light in their spectrum. Avoid LED lights above 3000K and/or labeled "bright white," "neutral white," "cool white," or "daylight white" as these lights will generally have a crisp, stark white color. These bulbs are usually labelled "warm white" but confirming the exact color temperature can be preferable. Choose a bulb with a color temperature of 2700K or lower, preferably 2400K.You may want to consider the following factors: Red energy (long wavelength) is plentiful in light given off by candles and flames - types of "light" that our bodies are already accustomed to being exposed to at night, and does not impact circadian rhythms. ![]() In general, you will want to look for bulbs that provide more red energy, and less blue energy, in their respective light spectra.
