I first heard of the Jil Lite Stern through at thread at CPFMP.
The design of the Jil Lite Stern is what "caught my eye".
STERN was developed for the usage in shipbuilding yard, where needs bright hand held light plus longer run time with minimum maintain cost for Primary battery.
The Jil Lite Stern uses 2 o-rings for protection and grip at the lens bezel assembly and the tailcap.
Uses a forward side clickie single stage.
The Stern came with this.
Osram GoldenDragon Plus 120lm/w
- Driven at 700mA
- Runtime : ( measured with LG2600mAh 18650 cell )
Total 4 Hours run.
Enforced B270 glass lens, AR coated both.
The beam tint on my Stern is a warm color.
SMO
OP
You can order with either a SMO or OP reflector but the reflectors are sealed. You need to purchase the whole assembly.
I noticed when swapping out the reflector assemblies the o-ring makes for a very good grip.
The beam is adjustable.

Rear view of the Lens Bezel assembly.
Voltage : 3.7 ~ 6V but Recommend to use 18650.
The battery tube has ample room, width size for any sized 18650 battery.

External view of the rear tailcap.

In the following beam shots I used Ultrafire Protected 18650 2400mAh fully charged.

Jil Lite Stern OP @ 32'
Jil Lite Stern SMO @ 32'

Pros
Good machining
Type III Hard Anodize is even in color between parts. no flaws in the finish.
Smooth threads
O-rings came lubed
Good advertised run time
O-rings on Lens Bezel Assembly and tailcap. Protects and makes a good grip while installing or removing the Lens Bezel Assembly or rear tailcap.
Ample room width size for batteries
Smooth beam when using the OP reflector
Beam is adjustable
Cons
Very ringy beam while using the SMO Refelctor.
No holster
Protruding lanyard holder. Will not tailstand.
Reflector assemblies are sealed
No extra switch boot rubber covers. (I wouldn't know how to change them).
Beams hot spot look off centerd in the SMO version.

The Jil Lite Stern throws a beam very far but while using the SMO it's very ringy. The OP beam is very smooth.
The Stern is very well made.
I like single stage lights and also side clickies.
I will probably use the OP reflector the most.
I also like that the beam is adjustable
