These guys lumonite do some interesting headlamps and made in finland(i presume unless sourced out to China). Either way some of the products look quite cool, but pricey as well. There is a headlamp clip mount for hard hats, amazon had them in stock so ordered. It was returned same day as unfortunately to me it was poor quality.
Clip
Where it went wrong for me, the single grub screw just could not hold the clip/bracket secure. It would still swivel around(extremely annoying for me). Tighten too much and the plastic housing is pushed open with the grub screw. Maybe a stronger housing, 2 grub screws with thinner base would work better. Thinner base as it is right in my eye line, so another problem was not wanting to see the plastic base on the rim of my hard hat.
Grub screw
Head lamp clip.................not too clever ether
I was really thinking this would get rid of the straps.............so promising
Under lip and how it locks
No good!
Olights head band is decent, much prefer the rubber section that secures the light. Easier to rotate if required and no metal/metal contact.....................needless to say its back on the hat with the petzl clips.
