Well done 
Thanks guys!
Not yet, tomorrow is planned a caving day, we are continue the world's longest salt cave survey
The tape is still holding but I didn't yet test it in a caving conditions, if it not hold i just replace it with screws as anybody else does.
Strong magnets are not an option because it will affect the compass for survey.
Also suction cups are not suitable since the helmet is not Smooth
Here are some beam shots, i drove to a remote location bus still some lights on the background and the moon:
Moon mode (3%):
Flood (90°) Low(6%):
Flood (90°) Medium(20%):
Flood (90°) High(40%):
Flood (90°) Highest(100%):
Spot (10°) Low(12%):
Spot (10°) High(100%):
That’s a cool looking headlamp YuvalS! I like that you can see all the wires and components. Kind of reminds me of The Terminator:
Orsm build YuvalS. I’ve enjoyed following you on your trip building this head torch. 
Epic build!!!
Well done on completing your build :THUMBS-UP:
Great headlamp
