I have no way of measuring lumen, so I don’t know, sorry!
The light now draws approx. 3.5A from a Lumintop 14500 USB-C cell if I remember correctly. A bit less than expected (thefreeman’s HDR Anduril 2 high efficiency drivers - update : FWxA boost driver - #319 by thefreeman), but I have yet to see if it is not the cell.
My button top H10 is too long, the damn light does not close with it
