What does "olson black" mean?
It's actually "oslon" as they have some connection to "osram-sylvania" and Black is the line of LEDs. I assume Flat is just their moniker for the domeless Black LEDs.
The black flat is the same size as the Cree xpg2 but is brighter and has more intensity.
i dont know if its actually brighter. xpg2 is capable of 1000 lumens. this olson led looks to be around 700 lumens. i think the die is slightly smaller then xpg2 there for the higher surface brightness
EDIT:
Xpg2 Die size is 1.47 x 1.47mm
Olson Flat black die size is 1.03 x 1.03mm
4am is harsh for the wesrcoasters. Any chance of a later time? I m new here if that s not an appropriate question.
The man running the sale is a west coaster... if 4am works for him, run with it. Why not just be happy that he's offering great lights at great prices?
They'll love this one, Vinh...
