Question 1: Energy-saving lamps are warm and white. If you don't rent a house, the room is small in summer and the light bulbs are easy to change. You change it into warm white in summer and warm yellow in winter, because white is refreshing, warm yellow is biased towards sunshine, and it always feels hot and uncomfortable in summer. Ha ha. If you choose energy-saving lamps for home decoration, it will be more troublesome to change them. Daming Fluorescence is right. It seems to be a professional seller of lamps, hehe. Bedrooms with low color temperature (2700K or 3000K) are better and look warm; The living room with high color temperature (5000K or 6500K) is better and warmer; The medium color temperature (3500K or 4000K) used in restaurants is better and appears peaceful. That's comprehensive.

Question: Is the led light warm white or white? L 1 Visual effect: True white is equivalent to the color of noon sunlight, and warm white is equivalent to the color of street lamps at night, giving people a relatively dark feeling, but it is warm and warm.

2 Different color temperature readings: generally, warm white led is 2800-3500K, normal white LED is about 5500K, and cold white LED is above 6500K K. ..

3 Difference of brightness: brightness is usually understood as luminous flux (in essence, brightness has a professional explanation, and the unit is Candeira/square meter), and the unit is lumens. Lumen is the degree of perception of light by human eyes. The lumen value of warm white led made of the same grade chip is slightly lower than that of ordinary white LED.

Question 3: What color is warm white light? Hello! Warm white is warm color, yellowish, and warm white light (color temperature 2700-3200K) is suitable for places where warm white light is needed. Warm white light is generally chosen for home decoration, and warm lighting can create a warm atmosphere.

Question 4: What are the white works with warm white and warm colors? For example, two shades of white are not very clear, one is blue-gray tone, and the other is yellow-gray tone ... In this contrast, yellow-gray tone is warmer than blue-gray tone ...

Question: Is there any difference between warm white, cold white and positive white of LED lights? The visual effect of 1: true white is equivalent to the color of the noon sun, and warm white is equivalent to the color of the street lamp at night. Yellow gives people a dark feeling, but it's warm and warm.

2 Different color temperature readings: generally, warm white led is 2800-3500K, normal white LED is about 5500K, and cold white LED is above 6500K K. ..

3 Difference of brightness: brightness is usually understood as luminous flux (in essence, brightness has a professional explanation, and the unit is Candeira/square meter), and the unit is lumens. Lumen is the degree of perception of light by human eyes. The lumen value of warm white led made of the same grade chip is slightly lower than that of ordinary white LED.

Question: What is the difference between warm white and positive white of led projection lamp? Warm white is yellow (similar to incandescent lamp), cold white is blue, and positive white is somewhere in between.

Question 7: What is the difference between the white and warm white of the bedroom downlight? Personally, warm colors are warmer in the bedroom and white is better in the living room.

A. Warm color light: The color temperature of warm color light is below 3,300 K. Generally, the color temperature of our energy-saving lamps, tubes and fluorescent lamps is around 2700K K. Warm color light is similar to incandescent lamps and contains more red light, which can give people a warm, healthy and comfortable feeling. Suitable for families, houses, dormitories, hospitals, hotels and other places, or places with low temperature.

B warm white light: also called intermediate color, its color temperature is between 3300K―5300K. For example, our plug-in tubes are generally around 4300K K, which is warm and soft, making people feel happy, comfortable and serene. Suitable for shops, hospitals, offices, restaurants, waiting rooms and other places.

C. Cold light: also known as daylight color, its color temperature is above 5300K K. For example, the cold light of our energy-saving lamps, plug-in tubes and fluorescent lamps is around 6400K K. The light source is close to natural light, which has a bright feeling and makes people concentrate. Suitable for offices, conference rooms, classrooms, studios, design rooms, library reading rooms, exhibition windows and other places.

Question 8: The color temperature table (K value) of spotlights is a constant value to measure the color of light, and it is the most common indicator of the spectral quality of light sources.

At K3300, it is cooler (bluish), k >；; 6000 is almost white! K stands for color temperature. According to this value, it can be seen that k > 6000 is positive white. While k < 3300 is warm and yellow.

Positive white light refers to white light with a color temperature above 4500K K K. Generally, the color of 5650-6500 K is similar to that of the sky at noon.

Warm white light refers to white light with a color temperature below 4500K K. Generally, the color of 2760-3260K is similar to that of the evening sky and light bulbs.

If the two are made of the same material (bracket, chip, glue, phosphor), the white one should be a little brighter.

The question whether the led light is warm or white mainly depends on what occasion you use it. Warm white is generally used for indoor lighting at home and some jewelry counters, positive white is mostly used for some office occasions, and cold white is mostly used for some lighting.

In short, it is still a concrete analysis of specific occasions.

Question 10: What do warm white light and white light of fluorescent lamps mean? Which is better? 18 square contains two lights. How many watts do you need? 1.2m warm white light is mild and not dazzling, and white light is also called bright white highlight brightness. It is recommended that you use led tubes to save energy.
