Fenix L2D Rebel 100 Premium

  Introduction:
Like the L2D CE Q5 Premium, the Fenix L2D Rebel 100 Premium belongs to 2AA Premium digital 'L' series flashlights from Fenix. L2D Rebel 100 Premium is 5th incarnation since the launch of 2AA L series comprising L2P V1, L2P V2, L2D, L2D CE and of course the L2D CE Q5 Premium. The Premium bin Luxeon Rebel 100 LED replaces the Q5 Premium LED. Except for the LED, it is similar in all other aspects to standard L2D CE. The main difference lies in the beam pattern and beam tint that we shall see in the beam shots. Machined from aircraft grade aluminium with hard anodize type III coat offering very good wear and tear protection, Fenix L2D Rebel 100 Premium is one of the best 2 AA lights reviewed so far. O-Rings are placed at various places to prevent dust and water entering the light. L2D Rebel 100 Premium meets the IPX - 8 Standard and is protected against water submersion, suitable for continual operation under water. Like the L2D CE Premium Q5, the Luxeon Rebel 100 version of L2D on turbo mode produces 175 LED Lumens of light. L2D Rebel 100 Premium is well built, high quality and exceptionally bright light. The electronics inside L2D Rebel 100 Premium are virtually same as the Digital 'L' series flashlights having Microcontroller (µC) Controlled drive circuit and 2 UI (User Interface) modes. In Turbo Mode the light operates with Max Brightness (175+ Lumens) and Strobe. The General Mode there are 3 light output levels and SOS function.

Note: Since L2D Rebel 100 Premium is very similar to Fenix L2D CE Premium Q5, a large portion of this review is taken up from there. This review is a comparison between 2 Premium thin film die LED based lights. i.e. the L2D CE Premium Q5 vs L2D Rebel 100 Premium

Light Features:
  • Premium binned Luxeon Rebel 100 LED
  • Can run on various AA sized batteries ranging from NiMH, Alkaline to Primary Lithium
  • Meets the IPX - 8 Standard Waterproof Specifications
  • Microcontroller (µC) Controlled Regulated Drive Electronics
  • Max Output, with Strobe in Turbo Mode

Light Operation & Output:
Light Operation: The Tail cap Switch in L2D Rebel 100 Premium is 'Reverse Click' type switch.
Turbo Mode: This mode is attained by fully tightening the bezel. It consists of Max Level [175 Lumens] and Strobe. The sequence alternates in cycle.
  • Press the tail cap button until 'click' sound is heard to switch ON the light
  • To change Mode, in ON condition, push the tail cap button until light is off for about half a second and release for next mode. The modes will cycle through
  • Press the button on tail cap until 'click' sound is heard to switch OFF the light
General Mode: This mode is attained by loosing the bezel. The General Mode consist of [12 Lumen]-[53 Lumen]-[107 Lumen]-[SOS].
  • Press the tail cap button until 'click' sound is heard to switch ON the light
  • To change Mode, in ON condition, push the tail cap button until light is off for half a second and release to enter next level. The modes will cycle through
  • Press the button on tail cap until 'click' sound is heard to switch OFF the light
Below is the chart showing total output levels for Fenix L2D Rebel 100 Premium with different types of AA batteries the numbers actually exceed the manufacturer specifications for this particular review sample. You may notice one peculiar behavior of light output on low and medium levels for twin Lithium Primary batteries and single Lithium-ion rechargeable cell. The light output is more than expected, this happens mainly due to combined voltage of battery is more than the LED Vf. The step-up converter goes in to drive mode and forces the light output to be more than the expected level. This is more pronounced in Lithium-ion battery where the terminal voltage for Lithium-ion rechargeable battery is about 3.7 to 3.9 volts where as the LED normally requires 3.4 to 3.5 volts. More voltage than required forces more current to flow through the LED than that required for the light level. More current translates to producing more light than expected.

Let's compare L2D Rebel 100 Premium output with L2D CE standard version & the L2D CE Q5 Premium. The charts show total output levels for various AA batteries, as you can see there is a distinct increase in overall brightness over the standard CE version but the output for L2D Rebel 100 Premium compares fairly well with the CE Q5 Premium version. If you have the standard version, it's definitely worth considering Rebel 100 incarnation. But what if you already have the L2D CE Q5 Premium? Well answer is yes; especially if you are looking for the tint quality and color rendering compared to Cree Q5 version.

In-Depth Review & Pictures:
Packaging: The review sample sent by Lighthound was duly packed and due care was taken for shipping the light. The packaging inside the box was well preserved. Have a look at the pictures below.

The Box built from thick paper board has a window that displays actual product. The window is covered with transparent PE.


Back side of box displays Fenix mission, product specification and company address.


Another view of the box

Package Contents: Let's open the box. Here is what you would expect. From left to right. First is Fenix User Manual second Hoister Next is the L2D Rebel 100 Premium, the warranty card and the lanyard attachment with some spare O-rings in a small plastic zip lock.


Size Comparison: About 3 times as big as a standard AA cell. Virtually identical to Fenix L2D CE Premium Q5 and despite the odd shaped battery tube, is comfortable to hold by hand. Pictured below size comparison between Fenix L2D Rebel 100 Premium and Fenix L2D CE Q5 Premium. From L to R: Fenix L2D Rebel 100 Premium, AA Battery and Fenix L2D CE Q5 Premium.



Bezel: Reflector in L2D CE Premium Q5 is built from solid Aluminium. Luxeon Rebel 100 LED is slightly miss-aligned and a bit off centered within reflector. The beam is very good in quality having 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 Luxeon Rebel 100 Premium has AR Coating. There is a o-ring seal between glass lens and the bezel body protecting reflector of L2D Rebel 100 Premium from dust and water. Top of bezel is chamfered on to prevent sharp edges.


Shown here is a comparison between reflectors, Fenix L2D Rebel 100 Premium on left and L2D CE Premium Q5 on right both with the LOP reflector finish.


Body: L2D Rebel 100 Premium is built from Aircraft Grade Aluminium. The Machining work is very good, there are apparently no any flaws in workmanship of L2D Rebel. To remove the machining marks and rings, the body is sand blasted and with hard anodized type III coating, the L2D Rebel 100 Premium appears to have a matt finish. Anodized type III coating also protects L2D from wear and corrosion in normal usage. The body of L2D Rebel 100 Premium 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 100 Premium 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 and uniform Hexagonal body with thick body walls.


Picture below showing side view of L2D Rebel 100 Premium 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 Rebel 100 Premium Components: Showing from left to right, L2D Rebel 100 Premium 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:
Below beam shot matrix shows Fenix L2D Q5 Premium on Left and Fenix L2D Rebel 100 Premium on Right, one of the interesting observations from these beam shots is even though the L2D CE Q5 is slightly brighter by numbers; visually, there is very less difference in brightness visually.
