How many watts is a bulb with a color temperature of 6500K

6500 watts.

1 watt is defined as 1 joule of work done per second.

That is, 3600 joules of work per hour. The kilowatt is a 1000-fold derivative unit of watts, which means that it does 1000 joules of work per second and 3,600,000 joules of work per hour.

The same goes for megawatts.

is defined as 1,000,000 joules of work per second and 3,600,000,000 joules per hour. Therefore, the meaning of megawatts can be thought of as generating 1 million joules of electricity per second.

Hello! Color temperature has nothing to do with wattage, but luminous flux is related to wattage.

K is the color temperature unit, which refers to the color of the light when the light is on, usually from 2700K to 7000K. The higher the color temperature, the whiter it is, and the brighter it looks visually, but it doesn't.

In the professional English of color temperature, warm color refers to 2700K, similar to yellow lights, Daylight (natural white) refers to 6400K, similar to the light color between yellow and white, and cool daylight refers to 6500K-6700K, similar to white lights.

Schematic diagram of color temperature.

The color temperature is below 3300K, and the light color is reddish to give a warm feeling and a stable atmosphere;

The color temperature is between 3000k-6000k, and people have no particularly obvious visual psychological effect in this tone, and there is a refreshing feeling, so it is called "neutral" color temperature;

The color temperature is more than 6000K, and the light color is blue, giving people a cool feeling.

Incandescent lamp. The light color is 2700k, which is suitable for the dining room bedroom to create a warm environment. 6500K is the standard color temperature of traditional home projectors, below this value, the picture color is warmer, and above this value, the picture color will be cold.

6500k and 5500k. It is an indication of the color temperature of the lamp. The 6500k light color is close to the color of the sun at noon. The color of the 5500K lamp is yellowish or warm white.

Color temperature (colo(u)r temperature) is the scale that represents the light color of a light source (the color seen by the human eye when directly observing the light source) in k (Kelvin). Light with different color temperatures will cause people to react differently in emotions, and we generally divide the color temperature of light sources into three categories:

A: Warm white light, the color temperature is below 3000K, giving people a warm, healthy and comfortable feeling, generally used in families, dormitories, residences, hotels and other places.

B: Natural white, also known as intermediate color, color temperature is about 4000K, soft light, so that people have a pleasant, comfortable, natural, feeling, suitable for shops, hospitals, offices, restaurants and other places.

C: Positive white light, color temperature above 6000K, close to natural light, bright feeling, make people concentrate, suitable for offices, classrooms, design rooms, libraries and other places.

A color temperature of 5000K indicates that the light emitted by the light source is natural white.

The color temperature is described according to the arrangement of red, orange, yellow, green, blue, blue, purple, from the perspective of visual perception, the higher the color temperature, the brighter people feel, when the color temperature is as high as 6500, people may feel disproportionate again, because the light begins to develop in the direction of ultraviolet rays. The lower end of the sensory wavelength band of the human eye is the red light emitted by the infrared electric furnace wire, and the high end of the sensory end is the ultraviolet light emitted by the ultraviolet light such as the electric welding machine. Lamps with a color temperature of 5000K are suitable for projector light and photographic light sources.

K is the letter of Kelvin temperature, and our Chinese name is "Kelvin", which is the same as the " " in our Celsius.

0 = , so 5000k here also refers to temperature.

To put it simply: color temperature is the color of the light. (The color of the light emitted by heating to different temperatures of black objects is the standard) see the middle section of the attached figure is the color temperature range of white light:

The light emitted by the phosphor used in energy-saving lamps under ultraviolet excitation has different luminous colors for different components, and the formula can be adjusted to change the color.

There is no reason here. The color temperature of the lamp is determined by the phosphor. The color temperature of 5500K is the color temperature of positive white light close to the noon sun, and it has good color rendering.

Hello, I'm an engineer who makes lights.

6200K is the luminous color temperature of energy-saving lamps, what is the color temperature?

Physics believes that all white light in the world is the light emitted by a black object (black body) heated to a certain temperature, and the lower the temperature of the black body, the more yellow the light color emitted, and the higher the temperature of the black body, the bluer the light color emitted. The light emitted by a black body when it reaches a certain temperature, and the temperature of the black body at this time is the color temperature of this light. For example, white light with a color temperature of 5000 K is the white light emitted when the temperature of the black body reaches 5000 K (the unit of Kelvin temperature).

This is not a very scientific definition, but it is easy to understand).

Therefore, the color temperature is divided into three stages from low to high in lighting: ambiguous white, positive white, and cool white. Different companies have different specific segments, and there is no unified segmentation standard, which is roughly segmented as follows:

3500k Warm White (white with reddish) gives a steady, warm feel.

3501 5500k Pure White (White in the middle) Gives a refreshing feeling》5501k Cool White (white with blue) Gives people a cool, cold feelingThe color temperature of some commonly used light sources is: 1930K (Kelvin temperature unit) for standard candlelight; Tungsten lamp is 2760-2900K; 3000k for fluorescent lamps; The flash is 3800k; The sun is 5600k at noon; 6000k for electronic flash; Blue sky is 12000-18000k.
