Macro Light for Nikon AF-S Micro 105 2.8G ED

For my other hobby I needed a light for my macro lens.

I didn't wanna buy, so i designed one by myself.
It works very well at a distance of 5 to 25cm (Macro :-D)
and also for Portrait ring light.

It fits perfectly on the sunshade of the macro lens
and the accu-pack-box can be attached at the belt by 2 cable ties.

for power I used a 12V 1,2AH Accu
for light I used 40x 5mm white LED with no lens
