Today LED lights are blue for one of two reasons. The first and most obvious reason is because the manufacturer developed the light to be blue. However, there are times when inferior quality LED s are manufactured that were intended to be bright white, but the result was much the same as early attempts. In other words, the second answer to the ...

Mar 12, 2019 · The enemy of the LED’s phosphor is the heat and UV radiation it emits during operation. Over time, these two forces degrade the phosphor and break down its components. The result is a fixture that used to give off nice white light but is now a little off—perhaps a bit blue or pink or green.
In addition, blue scatters more widely than other colors as it passes through the eyeball, Sliney said. Together, these two effects cause the intense blue light from a point source, like an LED, to spread out across the retina, interfering with other parts of the scene. It's called dispersion: Blue's shorter wavelength makes it refract at a ...
Oct 4, 2015 · Filtering for narrow spectrum light sources merely filters out the light. Also, the bluer LEDs often have UV output that causes issues. You need to start with a proper light source which would be probably 4300K or warmer White LED with a phosphor mix that gives a good CRI (broader spectrum white light).

You can swap the affected bulbs with higher quality...
Before we dig into the main topic, let’s first wrap our heads around LED lighting. This will give you a solid understanding of what LED is and how it the technology could affect the color issue.
The color of the light emitted is determined by the energy gap between the electrons’ energy levels, which is unique to each semiconductor material. In addition, some LED lights use phosphors. These phosphors absorb some of the blue light and emit light of a different color. This creates a broader range of colors to be produced by the LED. Furtherm...
