The lamp including batteries is not too heavy, so they can be worn with just adjusted tethers pleasantly and without too much pressure on his forehead and head. For regular jogging the weight may be too high (weighted 133 grams including batteries 'front-heavy' can there ever a bissl wobble), for hiking or work fits all, there sits the lamp 'wobble-free'. The (more than three, then the other screen settings do, however, at some point no sense because then lit it rather in the face) rasterization options, the inclination angle setting give me a more precise adjustment takes place on my 'built-in' joint (cervical spine).
At the highest level with 7 active LEDs has a really sufficient light intensity for's premises (no idea how many lumens, the light goes on a forest loosely over 20 m wide), in continuous operation, the three supplied batteries holding down approximately 8 hours (itself tested, sacrificed a pack of high quality batteries, eventually, however, the light intensity begins to decrease visible). In medium setting with 3 diodes can short-range (about 5m) well lighted and read in low settings with 1 diode easily a card, the operating time will be extended accordingly thereby. The more LEDs, the more the light intensity is increased both in the vicinity, as well as increases ranging width.
Only downside, the focus can not be selected, so the light thus not variable focus on a selected point. Who needs such a function (some like the example for cycling's) or a whole lot of lumens, which was to buy another lamp (and of course it also has to spend a lot more money). For all others LiteXpress Liberty 102 is clearly a recommendation.
