But now to the details:
1) light intensity and illumination: The luminous efficiency of the LS-950 is at night at the highest level simply fantastic. Have more than once experienced that pedestrians have turned puzzled or oncoming cars are out weights on country roads with respectful distance when I was with the LS-950. The lamp projected approximately 3-5m in front of the wheel about a 20-30m long bright trapezoid on the road, which provides enough light width for higher speeds. Directly in front of the tire a little scattered light is still drawn to the road in between, it is rather dark, but what for me is a total fine. Unfortunately, the light beam is relatively narrow, it will light up only about a roadway width of sufficient, which is sufficient for straight-ahead driving. If you want, however, not reduce cornering the pace at night and also recognize wildlife timely, coming at a second LS-950 on the handlebars not help - that's true then a bit expensive but then in terms of illumination already with halogen low beams of older cars models compete.
2) Battery life: ie light intensity can be varied in 5 levels. The battery lasts fully charged at the highest level by about 6 hours on the lowest level even 45 hours without interruption. An indicator on the display are immmer precise information on the remaining maturity for the current light intensity, which is then also respected in practice. The 5-level brightness adjustment is a nice feature to increase in 24-hour race or at the end of battery life with the remaining time can, without also losing a lot of luminosity. From pure driving her in different situations would be quite sufficient brightness and a 3-step control. The battery loses unused over several weeks little capacity. I've loaded it with the supplied USB cable and dispensed fast chargers with higher charging currents, which should be given the capacity in the next 3-5 years or less.
3) support: The ZL-700 is conceptually one of the best fixtures that exist currently for sale for headlamps. The holder can be assembled and disassembled without tools and can be adjusted not only in the tilt, but the upper part can be rotated horizontally to give the lower part can be mounted on the stem even normal to the direction of travel. On the handlebar bracket can be mounted front or back off because the symmetrical shell allows placing the lamp in both directions. Unfortunately, the ZL-700 is suitable against the notice for Trelock only conditionally for road handlebar with 32mm diameter. The rubber band is adequate in length to fasten the bracket to the handlebar, the curvature of the plastic part, however, does not fit the rounding of 32mm handlebars, making it rests only on 2 points on the handlebars and the lamp mainly by the static friction of the textile rubber -Bands must be kept. On aluminum bars that still keeps apart from potholes though provisionally reasonably well, on carbon handlebars I would not mount the holder because of slipping and scratching risk of the plastic part. The ZL-700 also has remarkably often be tightened because the textile rubber band elongates over time, and because an aluminum handlebar is not always dependent on the ambient temperature of the same thickness. News would be a screw holder, at least for racing cyclists probably the better choice. Trelock is the problem to improvise deliberately trying with a supplied rubber adhesive film, however, I hope that next year a new holder with the right curvature is taken for road handlebar in the assortment.
4) Housing: The plastic used on the lamp housing and the on / off switch operates very high quality, for heat dissipation an aluminum cover on top of the lamp fitted. The headlamp lens is, however, very sensitive to scratches - here should be careful when cleaning. The charging port is protected by a small rubber cover against pollution. Overall, rainwater lamp little harm, it is not waterproof, however.
5) Design, concept and scope of delivery: The built-in battery, the lamp has the advantage that you do not have to deal with cables and battery packs. There are no weak spots due to connectors, thus no loose contacts. Just put the lamp on the bracket, turn on and take off again after the trip - done. The battery can not be replaced if defective, but is nowadays also in electric toothbrushes and razors (tlw. Even in mobile phones) otherwise. For conformity with battery maintenance, storage and gentle charging should minimize the risk of defects and dwindling battery life here. Visually see the light due to the reflector technology is not as futuristic like the projector models from other manufacturers, but it is available in two colors (black or white) is available, enabling an optical adjustment to the wheel. The supplied charging cable is unfortunately a bit short, the PSU miss I do not really due to the large number of nowadays existing USB chargers in every household. The lamp, however, can not be charged with any mobile phone USB power supply when its electronics prevents this.
Overall, I can recommend the LS-950 for this price and very forgiving for the mentioned minor weaknesses in coverage and support 4 out of 5 points. If Trelock still nachbessert in bracket racing bikes, I'll buy without hesitation a second lamp. In order for the light cone is then wide enough for quickly driven curves.
