In-Depth Review & Pictures:
Packaging: The review sample sent by Fenix Light carefully packed arrived intact. The packaging inside was well preserved. Have a look at the pictures below.Back side of box displays Fenix mission, product specification and company address.

Package Contents: Let's open the box. Here is what you should expect. From left to right. First is Fenix Warranty, User Manual second, Fenix T1 & Hoister. In front is a little zip lock with lanyard attachment with some spare O-rings and tail cap boot.

Size Comparison: About 2.5 times as big as a standard AA cell. Pictured below size comparison between Fenix T1 and DereeLight CL1H V1. From L to R: Fenix T1, AA Battery and DereeLight CL1H V1.

Bezel: Reflector in Fenix T1 Tactical is built from solid Aluminium. Perfectly aligned Premium Q5 binned Cree 7090 XR-E LED in center within reflector. The reflector has LOP Finish. Beam is excellent quality with good throw and a distinct transition from Hot Spot to Spill beam. There are no artifacts in the beam. The Glass Lens of Fenix T1 Tactical has AR Coating. There is a o-ring seal between glass lens and the bezel body protecting reflector of T1 from dust and water. Bezel ring is made up of stainless steel and is chamfered on to prevent sharp edges at the same time it has 4 grooves with sharp edges.

Shown here is a comparison between reflectors, Fenix T1 on right and DereeLight Cl1H V1 on left both with the LOP reflector finish.

Body: Tank like construction with thick body walls. Fenix T1 is built from Aircraft Grade Aluminium. The Machining work is excellent, there are no flaws in workmanship of Fenix T1. The body is sand blasted and with hard anodized type III Natural coating, the T1 has a shiny matt finish. Anodized type III coating also protects Fenix T1 from wear and corrosion in normal usage. The body of T1 consists mainly of 3 parts; head housing lens, LED, reflector & Electronics, battery tube and the tail cap with switch. Head has non removable pocket clip attachment. The battery tube has diamond knurling offering a good grip. The laser engraving is done on battery tube to identify light model. The battery tube has fenix logo and T1 engraved. The overall T1 is very comfortable to hold.

Pictures below show side view of Fenix T1 highlighting the structural features on the bezel, battery tube & tail cap.

Fenix T1 Components: Showing from left to right, T1 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. Notably the Bezel side of battery tube has two O-Rings.

Thick positive contact tab placed over the PCB in head ensures good contact with battery as well as protects PCB from wearing out. Just outside the positive tab are the two quarter moon shaped disks placed equidistant from the center. This basically prevents negative terminal contact when battery is put in reverse direction acting as a reverse circuit protection.

The battery tube is about 4 mm in thickness that's a lot strong.

Tail cap has gold plated negative contact spring.

Beam Shots:
Here are two beam shots with Dereelight CL1H V1 on left and Fenix T1 on Right. The first Beam shot is with on Max light level for both next is the low light level on both.
