In-Depth Review & Pictures:
Size Comparison: About 3 times as big as a standard AA cell. Despite the odd shaped battery tube, Fenix L2D CE Premium Q5 is comfortable to hold by hand. Pictured below size comparison between Fenix L2D CE Premium Q5 and standard Fenix L2D CE is virtually identical. From L to R: Fenix L2D CE Premium Q5, AA Battery and standard Fenix L2D CE.


Another size comparison, From L to R: L2D CE Premium Q5 and Energizer AA Lithium battery.



Bezel: Reflector in L2D CE Premium Q5 is built from solid Aluminium. Although the premium Cree 7090 XR-E LED is perfectly aligned and centered within reflector, there is a gap in between LED ring and reflector. The beam very has a distinct transition from Hot Spot to Spill beam. The reflector has LOP Finish. There are no artifacts in the beam. The Glass Lens of L2D CE Premium Q5 has AR Coating. There is a o-ring seal between glass lens and the bezel body protecting reflector of L2D CE Premium Q5 from dust and water. Top of bezel is chamfered on to prevent sharp edges.


Shown here is a comparison between reflectors, Standard Fenix L2D CE on left with smooth reflector and L2D CE Premium Q5 on right with the LOP reflector finish.


Body: L2D CE Premium Q5 is built from Aircraft Grade Aluminium. The Machining work is very good, there are apparently no any flaws in workmanship of L2D CE. To remove the machining marks and rings, the body is sand blasted and with hard anodized type III coating, the L2D appears to have a matt finish. Anodized type III coating also protects L2D from wear and corrosion in normal usage. The body of L2D CE Premium Q5 consists mainly of 3 parts; head housing lens, LED, reflector & Electronics, battery tube and the tail cap with switch. the battery tube has flat faces machined offering relatively good grip. The laser engraving is done on bezel to identify light model with L2D Premium Q5 engraved on it. the battery tube has fenix logo and L2D engraved. On the other side of bezel there is a also a serial number engraved. The overall size of L2D flashlight is very comfortable to hold in hands.


One of the distinct feature of the LxD Series is the battery tube. It looks kind of odd having dissimilar diameters at different sections. At one point the diameter is very less, about 16.5 mm and it's 18.5 mm at the beginning and end of tube. Now considering the inner diameter as measured to be 14.5 mm, the wall thickness variation in battery tube from 1 mm in the weakest section to 2 mm at the thickest section. Comparatively, the L2P had a very nice Hexagonal body with thick walls.


Picture below showing side view of L2D CE Premium Q5 highlighting the structural features on the bezel and top of battery tube section. As you there is a band of straight knurling on bezel to offer more grip.







L2D CE Premium Q5 Components: Showing from left to right, L2D CE Premium Q5 Head, Battery tube and tail cap. The threads on body tube on tail cap side are anodized but the threads on bezel side of tube are not. O-Ring placed behind threads on both sides of battery tube offering good water resistance. The battery tube is of relatively fair in thickness and the tail cap has gold plated negative contact spring.


Thick positive contact tab placed over the PCB in head ensures good contact with battery as well as protects PCB from wearing out.


Beam Shots:
Here is a Beam Shot in smoke.


Below Beam shot Matrix shows Fenix L2D CE Premium - Q5 on Left and Fenix L2D CE on Right, one of the interesting observations from these beam shots is even though the L2D CE Q5 is considerably brighter by numbers visually, there is less difference in brightness visually.
