An 18350 battery weighs about 24g
An 18650 battery weighs about 45g
That’s a total decrease in weight of 24g, which is close to 30% just in weight of the total system.
From a performance perspective, 18650 all the way, but if you don’t need to use your headlamp for extended periods of time on high, that’s when the smaller and lighter package is preferred by many.
Its unfortunate that they don’t sell the battery tube separately and use glue in assembly.
So now you're comparing it with other brands? I was responding to your comment implying that the H04 Mini's small reduction in weight from the standard H04 wasn't worth the reduction in performance. To some people, it is. That's why people buy small(er) lights.
The H04 Mini is certainly smaller and lighter than the standard H04 and even though it might not be a large amount, the difference in weight and size is more important to some people than the difference in performance. I used the reasons I choose between my ArmyTek headlamps as an example, not as a comparison to the Skilhunts.
I beg to differ.
For my use it offers no advantage and it kills the biggest feature of H03 - very low weight.
I consider H03 to be a top notch headlamp and actually the best stock headlamp I’ve seen so far. H04 does not stand out from the crowd.
