Has a light wait front led head light housing (single led and plastic housing with switch). Zoom is nice as long as it doesn't change adjustment in tight spots by accidental pushing of it, we'll see on that. Switch step positions are On-Full-1/2 bright-flashing. 3 18650 batteries (same basic battery used by Tesla in the past) puts the weight at the back of the band, which is good as the front with it's light extension dominates the light position if you take the band off while the head is still attached to the band.
Removable head for tight spots that can't be seen while wearing it, hoping this works for spots such as underneath a car and needing to spot light deep up. My old light wasn't detachable so placing the light to shine somewhere else was all about what the batteries would allow for placement. Usually, not in the right spot because the entire headband and light needed to agree for hands free location of the beam. Usually, did not work as the batteries were too heavy for pointing and maintaining the light at the desired angle hands free.
Oh, forgot.... It comes with 3 batteries rated at 2200ma and tested to a actual 1400ma. If they last at all, that's maybe 4 bucks per battery right there, so that makes this a real bargain. That would put the head unit at $8. My last head light cost more, no batteries and not as good as this one overall. Now that I've used it for a few hours I appreciate the long battery life and that the zooming light unit is still small and not hanging out there very far.
