Their range is between 2700K and 6500K.
6500k vs 4000k. Difference Between 5000K and 6500K Bulbs When searching for daylight or color-balanced LED lights you may frequently come across two different color temperature options. Generally plants will grow optimally between the 2700k and 7000k range. I use 7000k on my aquarium.
Next we will introduce the application and impact of 3000K 4000K 5000K. The 3000k is almost identical to hps. If the bathroom features a bathtub and you want to be able to create a warm atmosphere as well consider using an additional layer of light eg.
3000K vs 4000K vs 5000K. 4000K is a cooler whiter colour than 2700K and 3000K. In this example both bulb families have the same brightness.
As one would expect is most definitely on the cool side when compared to typical warm white lighting options but is also on the warm side when compared to. Both 3000K and 4000K are still on the warmer side of the Kelvin scale as LED light fixtures can still reach 4800K 5000K and up to 6500K color temperatures. 6500K is a very cool white that is used to simulate day light.
When purchasing 6500K lights you must understand the spectrum of the light. For most LED lights colour temperature ranges from 2000K candlelight to 6500K cool white. What Does 4000K Look Like.
4000K is an often overlooked color temperature as it falls right in between warm white 2700K3000K and daylight white 5000K6500K color options. Full spectrum color temperatures are between 5000K-6500K. 2700K and 4000K light color are commonly.
