LF2 SSC P4 supports multiple types of AAA Batteries ranging from Alkaline AAA battery to rechargeable 10440 Li-Ion battery. LiteFlux LF2 is built from aircraft grade aluminium. It has hard anodizing type 3 coating offering good environmental protection, corrosion resistance and durability. LF2 has O-Ring Seals at different locations such as between bezel and lens and between battery tube bezel which provide a good water resistance. LiteFlux LF2 SSC P4 has a specially designed unique 2 stage twist switch. With Seoul Semiconductor P4 power LED as solid state light source, LiteFlux LF2 is one of the brightest lights in its category especially when powered by 10440 Li-Ion battery. LiteFlux LF2 SSC P4 has advanced drive circuit, with programmable Microcontroller (µC) offering great flexibility in operation and programming options. LiteFlux LF2 ships in beautifully packaged wooden gift box.

Light Features:
  • Unique 2 stage twist switch
  • Microcontroller (µC) Controlled with extensive programming options
  • SSC P4 LED
  • AR Coated glass lens
  • Supports multiple AAA Battery types
  • Can stand on tail, includes diffuser for excellent lantern type operation
Light Operation & Output:
Basic Light Operation: Simple, Twist the tail cap 1/4th turn anticlockwise to turn on the light in low mode, twist more anticlockwise to enter high output mode. To turn off the LF2, simply turn the tail cap clockwise fully. For advanced operation, please refer to the user manual.

In-Depth Review & Pictures:
Package: LiteFlux LF2 SSC P4 comes in a very beautiful wooden box with chamfered top edges. The company logo and name is laser etched on wood. The box has label identifying the product inside. If you are planning to gift this light, the box comes very handy.

Inside the box, you will find LiteFlux LF2 Flashlight, 3 Spare O-Rings, Candle Mode diffuser, lube jelly (silicone based) in small container. It is very thoughtful of LiteFlux to include the silicone lubricant.

Size Comparison: Pictured below is the complete LiteFlux Beacon Serials Family. From L to R: LF4 SSC (CR2 battery), LF2 SSC (AAA Battery), LF3 SSC (CR123 battery), LF2 Cree (AAA Battery), LF5 SSC (AA Battery).

The LiteFlux Family arranged as battery supported next to light sorted by height of flashlight in ascending order. From L to R: CR2 battery, LF4 SSC, CR123 battery, LF3 SSC, AAA Battery, LF2 SSC, LF2 Cree, AA Battery, LF5 SSC placed at right most end of the picture.

Another size comparison, From L to R: AAA Alkaline battery, LiteFlux LF2 SSC P4, AA battery. The LiteFlux LF2 SSC P4 is almost twice the size of AAA Battery in terms of length.

Bezel: Reflector in LiteFlux LF2 SSC P4 is built from solid Aluminium. The reflector has Light Orange Peel (LOP) Finish. SSC P4 LED is perfectly aligned and centered within reflector. LOP Reflector allows for a very smooth beam transition from Spot to Spill beam. Also, the LOP reflector removes any artifacts that might come due to LED or other defects.

Another view of bezel highlighting LOP Texture.

The Glass Lens of LiteFlux LF2 is AR Coated, you can hardly see it in front of the bezel. To ensure that dirt and water does not enter the light from bezel, there is a o-ring seal between glass lens and the bezel body protecting LiteFlux LF2 SSC P4.

Body: LiteFlux LF2 SSC P4 is machined from Aircraft Grade Aluminium. The Machining is very nice and is without any flaws. The body is sand blasted and has hard anodizing type III for wear and corrosion resistance. The body of LiteFlux LF2 mainly consists of 3 parts, removable bezel (housing lens and reflector), head housing Electronics and LED, battery tube. The head has grooves machined allowing easy twisting operation. The battery tube has machined slots allowing means of attachment either to key chain or to lanyard. There is a laser engraved dot on bezel determining the current position. This helps a lot when you need to know that you have to turn about 1/4 turn anti clockwise to turn on the light in low mode.

The bezel can be removed and replaced with the included diffuser, please see candle shots and comparison matrix further below. The diffuser does the job well diffusing light almost 360 degrees.

The body walls of LiteFlux LF2 SSC P4 are thick indicating strong construction.

LiteFlux LF2 SSC P4 Components: Showing from left to right, LiteFlux LF2 main body, Rechargeable NiMH AAA Battery and battery tube. Inside the bezel, you can notice the positive contact and special 2 stage switching mechanism.

Side view of LiteFlux LF2 SSC P4: Again showing from left to right, LiteFlux LF2 main body, Rechargeable NiMH Battery and battery tube all sideways. The threads are anodized, thus preventing wear and tear during operation. O-Ring placed behind threads on battery tube offers good water resistance.

Beam Shots:
Beam Shots LiteFlux LF2 SSC P4: Beam with biggish hotspot providing moderate throw and having excellent side spill very good for short distance and general illumination. The overall beam quality for LiteFlux LF2 SSC P4 is excellent. The beam shots below are taken with exposure compensation -1 to +2.

Exposure Compensation: -1 showing main hotspot

Exposure Compensation: +0 showing main hotspot, the side spill merges with hot spot very smoothly

Exposure Compensation: +1 showing main hotspot and side spill

Exposure Compensation: +2 showing main hotspot and side spill

Candle Shots:
Below is the Candle Shots Matrix showing LiteFlux LF2 SSC P4 on Right and a real candle on Left. The Candle flame glow and Diffuser over LED have same height and are placed at about same distance from the wall. To better understand how they compare notice background on the wall. For instance, if you see the first left image, you would see that the candle has almost equal amount of light throwing on the wall as compared to LF2 SSC. Where as in second image, you wall notice that there is a considerable change, the LF2 SSC throws much more light on the wall as compared to the candle. This fact is more aggravated when shots are taken at different exposure compensation levels.

Here is the runtime chart for LiteFlux LF2 SSC P4. The runtime tests was carried out in 4 ways.

Alkaline 1:
A depleted Alkaline battery was used to determine how it works with depleted battery. LF2 SSC Performed fairly well with about 36 Minutes till 50%.

NiMH: La Crosse 700 mAh NiMH AAA battery was used do this runtime test. The battery was charged fully and given rest for 2 Hours to settle down. The runtime of LF2 SSC P4 on NiMH was found to be good with about 51 Minutes till 50%.

Alkaline 2: Fresh AAA Energizer Max Alkaline battery was used to perform this runtime test on LiteFlux LF2 SSC P4. The runtime was found out to be around 25 Minutes till 50%. The light runs in fairly good regulation considering it is being powered by Alkaline battery. LF2 SSC P4 continued to provide light in 'moon mode' another half an Hour.

Note: After the Alkaline 2 runtime test, battery is not fully depleted yet. The alkaline battery has a property to 'recover' and revive itself and we use this fact to do the runtime test again. Also, It should be noted that during practical use, it would be on exceptional occasions that you would be using light for Hours at a stretch. What this means that if we allow the battery to recover itself, it becomes useful again. Although at a lesser capacity than the previous condition.

Alkaline 2 Re: The runtime test was again performed with the same battery used to do the previous Alkaline 2 test. As you can see, the light performs fairly well. The runtime was found out to be around 15 Minutes till 50%. We allowed the light output to go up to zero for this test. So, do you think the battery is now completely drained by now?

Alkaline 2 Re Re: The answer to the question in last runtime is here. After the Alkaline 2 Re test the battery was allowed to rest for about 8 Hours. Another runtime test for LiteFlux LF2 SSC P4 was performed. This time again, the light output was slightly lesser than the previous test but the light amazingly lasted till 14 Minutes till 50%.

LiteFlux LF2 SSC P4 Runtimes Conclusion: The runtime for LiteFlux LF2 SSC P4 on NiMH battery is very good at 51 Minutes. Also, what is being observed is that although the runtime for LiteFlux LF2 SSC P4 on alkaline test seems low at 25 Minutes, in practical situations you would experience a much longer runtime than that have a look at the chart below.
