Do led lights change color over time.

Because led is not a full spectrum light source early versions could produce a muddy color effect. It has so far been observed that for a given led type the change in light color will depend on operating lifetime thus lights of the same age can be expected to show no color difference relative to each other. The most common complaints were that blues looked green or reds ended up looking brown. Most manufacturers only provide colour performance data on a fixture that is fresh out of the box.

Strictly speaking an individual led can t change color. Led bulbs do last a lot longer than the average light bulb but no they won t last forever. Yes they will dim over time but a very very long time at that. They also work well for the kitchen.

This initial shift is likely due to changes in the led and package materials that began during manufacturing and continue for a short time when the led is first turned on. The electrical and thermal stresses on the components will have an effect on the colour performance eventually. The three leds are red green and blue so any of these colors can appear at a specific time simply by passing a current through one led. They are clearly the safest and most durable lighting option available.

The higher the kelvins the cooler and bluer the light. The notion that led light does not show colors faithfully is also due to a bad first impression. In addition they save quite a bit of money on energy and maintenance costs during their long lifetimes and are infinitely safer on the environment. Instead a color changing led is made up of three separate leds in one casing with a micro controller operating them.

Like all light sources they eventually fade over time. Deciding what light color to have where is a matter of personal preference. But remember that our led light bulbs will keep shining almost as brightly as they did when new for most of their lifetime whereas many other brands start to noticeably fade even after a year. The lower the number of kelvins the warmer and more yellow the light is.
