Black Flat & White Flat - Differencees

LED Flashlights – General Info
1

I need a little LED education.
Can someone explain the difference between Black Flat & White Flat LEDs.

Currently own a Skylumen Delta which uses a Black Flat emitter, very happy with the throw for a fairly small light, just wondering how the new Flat White LEDs differ in output & performance.

Thanks

black flat has higher vf and no neutral center pad, so electrical isolation is required

performance does not differ that much output wise

Is there a difference in throw?

The white flat is better, especially the 4040 version.
