3W High Power IR LED 850nm Z-power LED

As we can see from the picture as follow, this time we produce the high power LED with black LED frame. It's still IR LED 850nm wavelength but with black case. Most of time we just make it with white package. Then people might ask, what's the different between the white and black package in this high power SMD LED?
1, For the heat dissipatio: Black packahe might absorb much more heat than white package, which could potentially reflect some  heat when we use this SMD LED or IR LED under the sun(outdoors). 
2, For application: A black case might blend in better in certain environments while a white case coule be preferred in thers for its appearance.
3, Lighting: Even if we using the same chip material inside the package for lighting. There will have some different in brightness when we light up this high power LED in different package of case. The brightness will higher a little in white case than black.
In total, the color of LED package will make this LED got a different application or lighting result. It's totally up to what you going to need this exactly in your project.
