Color-changing LED lights are usually available as bulbs, strips<\/a>, or strings for decorative purposes. However, they have functional applications, as well, to help set the mood or vibe for activities like yoga or sleeping.<\/p>\n\n\n\n

Therefore, it is vital to understand how these lights work and how the colors elicit human responses. We have covered these topics in detail below, and let’s get right into it!<\/p>\n\n\n

Why Try Color Changing Light Bulbs?<\/h2>\n\n\n

Although these bulbs work like regular single-color bulbs, you can dynamically change their color temperature<\/a>, brightness, and color.<\/p>\n\n\n\n

For instance, you can design the bulb to change colors dynamically to match music or sound patterns. It is also possible to set them to cool white during morning hours, switch to warm white at night, or pick a color to set the mood in your bedroom.<\/p>\n\n\n

What Gives The LED Its Color?<\/h2>\n\n\n

The color produced by an LED depends on the energy level emitted by the semiconductor<\/a> used to make it.<\/p>\n\n\n\n

For instance, light-emitting diodes with an aluminum gallium arsenide semiconductor produce a red glow. Green diodes have a gallium phosphide semiconductor, while blue diodes have indium gallium nitride.<\/p>\n\n\n\n

A regular LED bulb has one of these semiconductors. However, a color-changing bulb contains all these semiconductors to control the produced energy level.<\/p>\n\n\n

How Do LED Light Strips Change Color?<\/h2>\n\n\n

Color-changing LED bulbs are three LEDs in one (red, green, and blue). These three are the primary colors and produce all other colors via different combinations.<\/p>\n\n\n\n

If current passes through one LED, it produces a single light color. However, powering the red and blue diodes creates magenta, while red and green merge to create yellow light. Lastly, a combination of blue and green produces cyan.<\/p>\n\n\n\n

\"Red,<\/figure>\n\n\n\n

Red, green, and blue LEDs<\/em><\/p>\n\n\n\n

You can widen the color range by varying the amount of current flowing into the LED to control the color intensity of each of the primary colors.<\/p>\n\n\n\n

For instance, controlling the current going into the red and green LEDs will give you all the color options between the two. They will produce yellow light when the red and blue LEDs are at 100% output.<\/p>\n\n\n\n

If red is at 50% brightness and green is at 100%, the light strip will produce a pink color. But if you switch the two (red at 100% and green at 50%), you will get an orange light output.<\/p>\n\n\n\n

Using AC on the diodes can create an impressive light show with millions of shades and colors. White light is a mixture of red, green, and blue. Therefore, powering all three LEDs to 100% brightness will create a white-color smart bulb.<\/p>\n\n\n

How Long Do Color-Changing LED Lights Last?<\/h2>\n\n\n

Color-changing LED bulbs can last 25,000 to 50,000 hours, depending on their quality. However, unlike incandescent bulbs<\/a>, they don’t burn out and go off immediately. Instead, they fade gradually, becoming dimmer towards the end of their life.<\/p>\n\n\n\n

Generally, LEDs last longer than other light bulb types because they:<\/p>\n\n\n\n
