For many common household lighting applications, people prefer warm white lights. It is relatively easy to pick up a warm white incandescent bulb just about anywhere, but if you want to save electricity and money with one of the new LED light bulbs, picking a good warm white LED light bulb is a little more complicated. For example, you want a LED g9 warm white light, but you didn’t know whether it is suitable. This article provides some advice and recommendations on picking the best warm white LED light bulbs.

When we describe a light as warm white, we are referring to its color temperature. Technically, the concept of color temperature is based on the relationship between the temperature and radiation emitted by a theoretical standardized material (a so-called black body radiator) that has been cooled down to a state in which all molecular motion has ceased. So, simply put, the color temperature is a measurement that is used to define the color of a light emitted by the bulb. We typically think of the color temperature in terms of the whiteness or warmness of a light source: "Warm White" = 3000 Kelvin; "Neutral White" = 3500 Kelvin; "Cool White" = 4100 Kelvin and "Daylight White" = 5000 or more Kelvin.

LED light bulbs are available with a wide range of color temperatures, but the warm white LED light bulbs that produce a light similar to a traditional incandescent light used in general home lighting are more expensive because more or brighter LEDs are required in the bulb. Since cool white is the natural color of LED light, it is brighter, whereas chips that emit a warm white light require a phosphorous "filter" to "warm" the color temperature, thus reducing the chip's brightness. So, a warm white LED bulb is an LED light bulb with a color temperature around 3000K that will produce a warm light similar to that we typically expect from an ordinary household incandescent bulb.

There are a growing number of LED light bulbs on the market today that are marketed as warm white bulbs. Which ones are the best? Below we discuss a couple of the best we have come across for replacing common household light bulbs.
