Interesting light with weaknesses

I have numerous Batterieruecklichter behind me, and must
say that Hiro is ... interesting. It is the smallest
StVZO compliant luminaire that is I've ever seen. Unfortunately bought
you look at the by using the tiny and this country more
rare N / Lady-cell batteries. With two NiMH batteries with
500mAh - which I had to get me otherwise, because Amazon does not
matching offering - it took still more than 22 hours until the
Battery status indicator from green changed to red.

My concerns about the 1-LED technology have not been confirmed:
The 3mm from the housing protruding lens distributes the light with
up to 260 °.

Furthermore, Sigma seems the "Waterproof" serious about,
I a very close when opening the case in every form
felt fitting rubber gasket get. I have to tidy
pry the recommended in the manual 10 ¢ coin to make it
aufzubekommen what the "noble Rubber Touch case" after a few
Has produced battery changing deep notches.

One more thing: Unlike my Trelock LS610 leaves
the Hiro off easily even when wearing gloves. Thanks for
Read.
