    Delivery took about slightly longer than a week and comes in the box as shown on the product page. The overall quality of the light is good. The clicky cycles thru 4 modes high-med-low-strobe although I can't see why I would need strobe pointing front when its so flashing bright up front. After I... Read more

    Pros: Great light beam with changing focus. Durable battery - really 4 h on full power. Other 3 mode also useful. Light survive few heavy rain drives. Good work out in light must be mentioned. Cons: Indicator for battery on ON-OFF button is not perfect. Go from blue just few minutes before out.... Read more

    Recieved it today and so far I'm very happy with it. I've already pulled it apart and put it back together. I haven't rewired it yet, but if you want to disable to stupid flash modes (for the electronics-minded people out there) bridge pins 1 to 5 on the IC inside it. This sets it to full on need...

    This truly is an exceptional lamp to use for night time mountain biking. It has four settings, high, medium, low and strobe. It also has an adjustable been which varies between a narrow spot and a wide beam which illuminates the trail perfectly. The lamp,is well made and easy to setup and use the... Read more

    Works as intended. Can adjust to a wide angle which is great for night riding. 1000 lumins is enough in combination with a small pencil light on my handlebars. This configuration or vice versa seems to be the best for night riding in teh hills around us which is dark and quite technical. None so... Read more

    Housing of the lamp is high quality, feels well built. The luminance range is very good. Zooming function of light works well. Battery life is quite long. Atached cabels are waterproof tight when connected together. The lamp is better for use on bike, since head strap and the housing of batteries... Read more

    Zooms to a very nice beam. You can see the led element shape clearly, so certainly the optics are worth while. Sturdy seeming casing. When ones zooms to narrow beam, the beam is rectangular due to rectangular LED element. Might be a good thing just as well, depending on your needs. Gave the lamp... Read more

    This is a very well built product, with aluminum case, the light is very good and strong. The materials seems to be of optimum quality. The packaging is very good. The power of the beam light can be adjusted from a blue button on the back, which is always visible because us illuminated. I would a... Read more
