I am very partial to the hurlkins orbit headlamp, similar to the one you mentioned. It’s 3x the price
, but the light diffusers built in do wonders for the normal shadowing you get from these types of headlamps.
I show people the difference in a dark engine
compartment all the time.
No they are not great for the marine environment
, and the connectors will corrode. I get about 3-4 years out of one. Still worth it.
When I give someone a hand on a project
, I bring my own headlamp, and they almost always order one that night.
