Picked up a light recently from a budget company and I am quite suspect of it. Claims to be XPG R5 but doesn't seem as bright as I would like. In addition, in high mode it has quite a strong blue tint and fades quickly, but in lower power modes has a much better color.
A quick glance at each respective data sheet seems to show identical dimensions on the ceramic substrate. I didn't see dimensions for the die itself. One possible hint would be the middle picture on the left side of page 14 of the XP-C data sheet

It seems to have sort of a crescent shape below the dome, but I can't tell from the picture what that is. Is it a cutout of some sort? I don't have a known XP-C for comparison.
If anyone could post a pic of both LED side by side for reference, I would appreciate it.
Thanks
