Cool white light contains more blue light and looks brighter to the eye (this is why cool white bulbs have a higher lumen output when compared to the equivalent warm white bulb). It also seems people from sunnier countries tend to prefer white light compared to people from cooler countries who prefer more warm light.
Is cool white brighter than daylight?
The Range of Color Temperature
The three primary types of color temperature for light bulbs are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.
Which is better for reading cool white or warm white?
The warm light of 2,500 to 3,000 K will help you relax while reading and rest better after that. The natural light of 4,900 to 6,500 K is the best solution for eyes that allows comfortable work. The cold light of 6,500 K offers an excellent level of brightness and improves overall attention.
Which light bulb is the brightest?
A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb. Typically, the higher the wattage, the higher the lumens, and the more light output.
landscaping light bulbs.

What color temperature is the brightest?
In general, LED lighting color temperatures range from 2300K to 6000K. Despite what you may assume, lower Kelvin lights produce the warmest light, while higher Kelvin lights produce the brightest, coldest light.
Is cool white light bad for you?
The Australian National University found that overexposure to “cool” or “bright white” fluorescent bulbs for over 45 hours a week put your eyes at risk for many health issues, such as cataracts and pterygia. The reason why these light bulbs are so bad for your eyes is because they emit an amount of UV rays.
Are daylight bulbs bad for your eyes?
Bright white and cool fluorescent tube bulbs and incandescent bulbs emit the most UV radiation and cause the most damage to your eyes. … They also state that extended exposure to sunlight, especially in the teenage years and for those that don’t wear eye protection, can also lead to eye damage.
Which light is better for eyes warm or cool?
Warm white is more relaxing for the eyes and softens the skin tone and reduces imperfections. We all look better in warm white. We recommend Cool White for: … In a nutshell, we can conclude that Cool White LED lighting best suits practical applications while Warm White is best for living areas.
Which light is best for eyes?
Warm light is best for the eyes. This includes filtered natural light and light produced by incandescent and LED light bulbs. Spread out lighting in your home and workspace to ensure sufficient lighting.
Is white LED light bad for eyes?
The basic technology for producing a white light combines a short wavelength LED such as blue or ultraviolet with a yellow phosphor coating. … The whiter or “colder” the light, the greater the proportion of blue in the spectrum.
Are daylight LED bulbs bad for you?
Unlike other energy-efficient types of lighting, the LED bulb does not emit polluting radiation and therefore does not pose a health hazard. It is important to note that LED bulbs operate at low voltage and are therefore considered safe compared to any other lighting systems (LED operates at low DC voltage 12 V).
Which bulb is brighter 60W or 100w?
Answer: The bulb rated at 100 W will be brighter. When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb.
How do I choose a bright light bulb?
More lumens equal brighter light; fewer lumens equal dimmer light. Standard 100-watt bulbs produce about 1600 lumens. Watts: The amount of energy a light bulb uses. The lower the light bulb wattage, the lower the electric bill.
Which color temperature is best for eyes?
Color temps are measured in degrees of Kelvin, with the scale ranging from 1,000 to 10,000. During the daylight hours, it’s best to keep your monitor relatively cool with a default color temperature of 6,500K. At night, the color temperature should be warmer, and around 3,400K.
Is 6000K brighter than 8000K?
While it might seem a bit odd, the 6000K LED headlights are brighter than the 8000K headlights – and there’s science to back this distinction. Light intensity is measured in Kelvin units, which are abbreviated to K.
Which is brighter 3000K or 5000K?
A 3000K LED bulb produces soft white or warm white or yellowish color light. … A 5000K LED bulb produces a bright daylight kind of color. So, it’s good for bathrooms, basements area and your study room.
