Lighting has come a long way since the days of primitive oil lamps and candles. From incandescent lightbulbs to fluorescent lighting, there are a variety of ways to light up a room. But what is the difference between incandescence and iridescence?
In this blog post, we’ll explore the differences between these two types of light and how they can be used to create a unique atmosphere in any space.
Differences in definition

The terms “incandescence” and “iridescence” are often confused because they both refer to the phenomenon of light being emitted from a surface. However, there is an important distinction between the two.
Incandescence is a type of luminescence, which is the emission of light as a result of heat. This is the type of light that is generated by a light bulb or a candle flame. On the other hand, iridescence is an optical phenomenon in which the surface of an object appears to change color as the angle of view or the angle of illumination changes.
It is caused by the reflection of light from the surface of an object, which results in a rainbow of colors. Iridescence is often seen in soap bubbles and the wings of certain butterflies.
Differences in physical properties
Incandescence and iridescence are two physical properties that appear to be similar at first glance, but they actually have different underlying characteristics. Incandescence is the emission of light from a hot surface, while iridescence is the result of light being reflected off a surface in a changing spectral pattern. Incandescence is a steady and consistent light, while iridescence has a shimmering and often changing appearance.
Incandescence is a steady and consistent light, while iridescence has a shimmering and often changing appearance. Incandescent light is generated from a heat source, while iridescence is created by a physical phenomenon known as thin-film interference. Both properties can be found in nature and in everyday objects, but the differences in their physical properties makes them unique.
Difference in applications

When it comes to lighting, there are many different applications to consider. Two popular choices are incandescence and iridescence. While these two terms may sound similar, they actually have distinct differences.
Incandescence is the emission of light from an object that has been heated to a high temperature. This type of light is created when a filament is heated in a vacuum, and the resulting light is bright and uniform.
On the other hand, iridescence is the appearance of different colors depending on the angle of view. This type of light is created by interference between light waves, and it produces a unique, rainbow-like effect. While both of these types of lighting can be used for decorative purposes, incandescence is generally more effective for illuminating a space, while iridescence is often more suited for creating unique effects.

Difference in color
When it comes to color, there is a big distinction between incandescence and iridescence. Incandescence is a dull, uniform color, while iridescence is a shifting, rainbow-like appearance.
While the former gives off a simple, warm glow, the latter creates a dazzling effect that is truly eye-catching. Iridescence is often seen in nature, such as the rainbow-like sheen of soap bubbles and the shimmer of a butterfly’s wings.
Incandescence, on the other hand, is found in man-made items, such as light bulbs and candles. So, while they may look similar, incandescence and iridescence are two very different colors and effects.
Difference in cost
When it comes to illumination, there is a significant difference in cost between incandescence and iridescence. Incandescence is a traditional form of lighting that uses heat to create light, whereas iridescence uses light to create its own light source. Incandescence is more expensive due to the amount of energy consumed in the process, whereas iridescence is a more cost effective solution due to its low energy consumption.
Incandescence is more expensive due to the amount of energy consumed in the process, whereas iridescence is a more cost effective solution due to its low energy consumption. Additionally, incandescence has a shorter lifespan than iridescence, as the bulbs used in incandescent lighting burn out more quickly. This means that, while incandescence may be more expensive upfront, it will also require more frequent replacement, making it a more costly option in the long run.
Iridescence, on the other hand, is a more cost-effective and longer lasting option for illumination.
Conclusion
Conclusion:The main difference between incandescence and iridescence is the source of their light. Incandescence is the result of heat being converted into light, while iridescence is caused by light being refracted by an irregular surface.
Incandescence produces a steady, even light, while iridescence produces an ever-changing, rainbow-like effect. Incandescent lights are used primarily as a source of illumination, while iridescence is used more for its decorative effects.
