This company has been making titanium lights since 2005 and has now decided to enter the international flash light market, the TITANER ET20 is their entry model. This is a two level light where the light is off with tight head, loosen the head will select high and loosing it even more will select low (From off to low is about half a turn). The light is, of course, made of titanium.
The light is delivered in a small cardboard box and as can be seen on the photo it is marked jewelry (It might be a good idea to substitute another box, if the light is used as a gift to a girl friend). The box contains the light, two spare o-rings, a split ring and an instruction and specification sheet.
The light has a deep LOP (Light Orange Peel) reflector with the led XP-G led at the bottom. There is some GITD (Glow in the Dark) stuff around the led.
The head does not have rifling or knurling, but instead a milled pattern that also works to improve the grip and makes the light look different from other lights. It is also possible to get the light with a more regular pattern.
Moving to the backside of the head the battery connection and the two switches can be seen. These switches are pressed down when the tail is tightened, one controls high/low, the other controls on/off. There is not circuit board visible in this light.
Moving on to the battery tube / tail, the threads is the first thing to look at. They do not look like any other AAA light I have seen, these are square cut and very solid, I do not believe they will ever wear out. It requires just less than two turns to take the battery tube off. There is also an o-ring in a grove, this makes the light waterproof and secures that the light will not unscrew itself.
Inside the battery tube is the usual spring.
On the side of the battery tube is the brand name milled in a special font.
The back end of the battery tube has a very solid eye that can used to mount the light in a key chain
This light is one of the best mechanical build AAA lights I have seen, it looks like it will last forever, it also has a very easy user interface. The huge difference between high and low gives a real low in a two level light, but I would have preferred that low activated before high and a driver that worked better with alkaline. I like the design with the pattern on the head, instead of the typical knurling or groves.
Technical specification and measurements
This light is designed for 1.5 volt AAA batteries (Alkaline, NiMH, Lithium).
Measured size and weight:
Length: 80.9 mm
Diameter: 14.6 mm
Weight: 38.3 gram with eneloop
The light uses a Cree XP-G R5 led.
In the above table I have used 800mAh eneloop batteries for measuring and estimating the runtime. The estimated lumen are based on the specified 60 lumen and then scaled according to measured brightness. When turned off the light has a small current drain, but this is low enough not to have any impact on battery life.
The voltage scan show that the light is stabilized down to around 1 volt, but this stabilization has a down side, the light can use up to 2 ampere from the battery! The driver did jump up and down in brightness and current when doing this measurement, making it impossible to get an exact curve.
On high the light uses a lot of current and with an alkaline the driver has trouble stabilizing the brightness, but NiMH batteries works fine.
The light uses current control and has no flashing modes.
