SupFire F3 L2

supfire f3 l2

 
I received these lights recently, ordered both Supfire F3-L2 and Supfire F3-XPE (Cree Xp-E). They are same except F3-XPE has a different driver, and LED. F3-L2 means it uses Cree Xm-l2. Great zoomie lights considering their price.

Supfire F3's height is only 125mm and head size is 35mm. L2 has 5 modes High, Mid, Low SOS and Flashing mode, XPE has 3 modes High, Low, Flashing.

Some specs from dealer for L2: Tube diameter: 28mm, Tail diameter: 27mm, Lanyard length: 18cm,  Weight: 114 g, Battery: 18650 / AAA (with holder, 3 x AAA in series) , LED: Cree XM-L2 6500K
