I did some macros
Did some photos with my reverse adapter for DSLR
Used Canon Eos 50D with 16-35mm F2.8 lens
@F=18 and reverse adapter ISO400 1/160s
light with a 1400 lumens 5000K NW flashlight from the side
First Lite On

this LED has a electrical neutral middle thermal pad for DTP stars
The active area is a lot bigger than on he Nichia LED, so it throws less
my LED has a surprizing low forward voltage of 3.46V @0.7A
second Nichia NCSU276A U365
die size 1x1mm
LED forward voltage of my one 3.84V @700mA

Improoved the resulution with a extender
Pictures cropped in full resolution
that is already dedomed from the shipping incident which clemence had, so he got replacements and donated the LED
I can live with as its going into a reflector light
the dust particle got removed later with compressed air
.
The IR Osram LED is hard to photograph as its dome is really high and acting as a very strong lens
