This Liberator model is the first one introduced by First Light.  I was my first unit from them and one I use to this day for audits and assessments.  The light uses their first generator 80 lumen LED rather than the current 120 lumen one.  Also this unit does not have a belt clip but come instead with a belt holster.  At 80 lumens max output the light steps down to 40 then 20 lumens allowing three levels of adjustment.  It is a soild well proven tool anywhere an good light is required and frankly the 80 lumen output is more than enough for any work you might be doing.  For most uses I leave the light set on low and just hit the main power bar for momentary full power use.  A great light now at a great price including a very well made holster.  The numbers are limited and when the stock runs out they will no longer be offered.
