In-Depth Review & Pictures:
Package: LiteFlux LF4 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 LF4 Flashlight, 3 Spare O-Rings, 3 Color Filters, 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: AA battery, LiteFlux LF4 SSC P4, AW RCR2 battery.

Bezel: Reflector in LiteFlux LF4 SSC P4 is built from solid Aluminium. The reflector has smooth Finish. SSC P4 LED is perfectly aligned and centered within reflector. Even though the Reflector is smooth, the beam very has a very soft transition from Spot to Spill beam. There are no artifacts in the beam.

The picture below shows closeup of LiteFlux LF4 Reflector with perfectly aligned LED.

The Glass Lens of LiteFlux LF4 is AR Coated, you can barely 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 LF4 SSC P4.

Body: LiteFlux LF4 SSC P4 is machined from Aircraft Grade Aluminium. The Machining is good, without any flaws. The body is sand blasted and has hard anodizing type III coat for better wear and corrosion resistance. The body of LiteFlux LF4 mainly consists of 2 parts, head housing lens, LED, reflector & Electronics and the battery tube. The head has grooves machined providing good grip to hold and 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.

Pictures below showing side view of LiteFlux LF4 highlighting the structural features.

The body walls of LiteFlux LF4 SSC P4 are relatively of good thickness indicating fairly good construction.

LiteFlux LF4 SSC P4 Components: Showing from left to right, LiteFlux LF4 Head, AW CR2 Lithium-ion Rechargeable Battery and battery tube. The threads are anodized, thus preventing wear and tear during operation. O-Ring placed behind threads on battery tube offers good water resistance.

Inside the bezel on left, you can notice the positive contact and special 2 stage switching mechanism. The battery tube shown on right has contact spring. The spring also prevents battery rattle in the tube.

Beam Shots:
Beam Shots LiteFlux LF4 SSC P4: Beam with good hotspot providing moderate throw and having very good side spill for medium distance and general illumination. The overall beam quality for LiteFlux LF4 SSC P4 is excellent. Here is the Beam shot matrix comparing Low and High in default UI mode.

Candle Shots:
The 3 color filters accompanying LF4 SSC P4 work excellent. Here is a combined image with all filters, these images are borrowed from LF3, the light output is fairly similar to LF3.

The filters with diffuser can be used for mood lighting or even be useful in case of emergency.

Red and Blue filters used along with diffuser appear very pleasing.

Below is the Candle Shots Matrix showing LiteFlux LF4 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 LF4 SSC. Where as in second image, you wall notice that there is a considerable change, the LF4 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. (All images below are borrowed from LF3, the light output is fairly similar to LF3)

Here is the runtime chart for LiteFlux LF4 SSC P4. The runtime for LiteFlux LF4 SSC P4 with AW Li-Ion RCR2 on High is 45 Minutes until the battery protection kicks in. LF4 SSC Runs in good regulation and for the RCR2 battery runtime of over 45 Minutes is very impressive especially considering the total output of about 50 Lumens and use of rechargeable Li-Ion Battery.
