As we can see the picture as follow, there are 3528 SMD LED case with 4 leads and there have 3 position inside of the 3528 SMD LED. Which means we can put it up with 3 LED bare die inside of it. For this product, we just put 850nm and 400nm inside. These two kinds of LED can emits different lighting color and will have two kinds of lighting result. Since it's a custom LED, you can put it with different chip inside as your design of your project. Do you need some custom LED for your project? 1 chips 3528 SMD LED, 2 chips 3528 SMD LED or 3 chips 3528 SMD LED, we all can produce it as your requirement. Contact us now~

*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.

- Golden Wire Connection -

* In order to keep every one of LED's long lifespan, BestLED factory use high pure gold wire for inside circuit connection

- Packing -

*We package it with vacuum packing after tape it as a reel
