What is the color temperature? What's the difference between 3200k and 5500k LED bulbs?

Color temperature is the color change that human eyes feel when light waves are at different energies.

Difference:

1, different colors: the light at 3200k is light and yellow, which is mild and belongs to warm white. The color of 5500k light is whiter and closer to sunlight, which belongs to cold white.

2. Different rain and fog effects: Compared with traditional halogen lamps, the more popular LED lamps in the market have higher brightness, but it is more difficult to concentrate light. Because halogen bulbs emit light at points, the light emitted by point light sources gathers together through the reflection of reflective bowls and spreads evenly forward, while LED bulbs emit light at the surface, which is easy to astigmatism, so the paving effect is poor.

3. Different color temperatures: the color temperature of standard sunlight is about 5200~5500 K, that of news photography lamp is about 3200 K, and that of general tungsten lamp is about 2800 K. ..

Precautions:

1, LEDs with the same wavelength and color temperature will have the same color. This large combination lamp is particularly important. The same lamp should not produce too much color difference.

2. The leakage current is the current when the LED conducts electricity reversely. We suggest using LED products with smaller leakage current.

3, waterproof ability, the requirements for outdoor and indoor LED lights are different.

4. LED lighting angle has a great influence on LED lamps, which requires many different lamps, such as LED fluorescent lamps. It is recommended to use 140- 170 degrees.

5. The size of LED chip also determines the quality and brightness of LED. Try to choose a bigger chip when choosing, but the price is different.
