olight O'Pen 2 - the revolutionary lighting pen

I buy Zebralights for the small size and NW/CRI options and like the unibody design. Zebralight also have the same Olight problem of poor/green tint and I returned a few Zebralights because they were horribly green. In terms of build quality, Zebralight is good but Olight is perfection. Holding a brand new olight out of the box is like the first time I owned a brand new Iphone. That feeling of holding an ultra premium grade luxury item, a perfect piece of art that you marvel at for the first few hours.

While Zebralight has its own unique, customizable UI, I love Olight UI’s simplicity (despite some new models lack moonlight). Olight also makes the most efficient drivers, even more so than Fenix and their output and throw ratings are spot on or conservative. Zebralight and Acebeam lumen specs are usually 15-20% higher than what I actually measure.

Of course it’s not an apple to apple comparison because the CCT and CRI are not the same but it’s obvious even if they are the same, the Olight will still be much more efficient. The difference in emitter efficiency is probably 20%

The recent Olight Perun is rated to run 500 lumens for 240mins (4hrs) on an 18650!!! That kind of efficiency is unheard of. Though I will never buy the Perun because of the horrible tint, which I will never use.
