            the colour ones are really good, i use flat-top ones to indicate various voltages in psu circuits.

            but your after high-flux white - i never had anything like that.
            i do know the main maker of those is not CREE, it's Nichia.

                  LOL, I like the "Sealed pack of 200 pcs.", they are used so what's the purpose of saying 'Sealed pack', trying to make it looks like new? $150?????

                      They look like they don't have leads cut or soldered, not sure if they're really "used" ...
                      I think these LEDs are NOS not used... though better to clarify.
