- 2835 SMD LED -

2835NW-40K30L3W

2835NW-40K30L3W is a phosphor converted white SMD LED. We mixed the phosphor with the epoxy for the LED lens. That's why you can see there have a yellow color on the top of the white LED. These 2835NW-40K30L3W is a 4000K Natural White 2835 LED, then people might confused, what is the 4000K? What's that mean and how we can produce this different color of white LED? "K" (Kelvin) can as a symbol for color temperature in LED industry. normally, white LED can be like 1800K, 2500K, 3000K, 3500K, 4000K, 5000K, 6000K or even 10000K or 20000K. With the number goes large, the color of the white LED will be more bluish. And with the number go down, the color will be more yellowish. Blue always can make people feel cool and yellow looks warm, that why some people can also name the white LED as warm white LED and cool white LED. Do you need some white LED for your project?

*Luminous Intensity is measured by ZWL600.

*q1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

*lD is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
