Color temperature is important for LED lighting. Normal Household light bulbs have a color temperature of around 2700 Kelvin. These bulbs have a nice yellow glow that is very familiar and comfortable. The noon time daylight or the color of a flash bulb is about 5000 Kelvin. This is great for taking pictures and one would think that it would be perfect for lighting. However, the color of 5000-6000 Kelvin is very similar to the new headlights on some cars, which is blue/white in color, which is very unpleasant.
It just happens that the cheapest LED lights have a 5000 Kelvin color temperature. Driving around last year at Christmas, these lights were very noticeable and unpleasant to view. I own some of GE LED light strings, which are generally more expensive, but the color temperature is 2700-3000 Kelvin. So, when you are looking for LED lighting, if there is no indication of the color temperature, do not buy them. Ensure that you get the lights that have a temperature of 2700-3000 Kelvin, you will not be disappointed.
