Excelente producto, cumple con todas las especificaciones descritas

Esta muy genial alumbra súper bien

De las mejores lamparas que he tenido, son garantía de resistencia y calidad, la tengo desde hace mas de 2 años y aun funciona sin problema, lo único que deben mejorar es el plastico que protege el centro de carga, ya que está débil su acoplamiento y se cae fácil, por eso le entrá agua, polvo y demás basura, lo que ocasionó que el centro de carga se oxide y ya no carge, decidí llevarlo a un taller de celulares y alla le cambiaron la pieza y ya quedó como nueva, saludos

This is my third Cygolight product in 12 years. I still have the first one, so these things are built to last. This light is perfect for urban use, or as a backup for mountain biking. The brightness is accurate (about 550 lumens) but more importantly, the beam is evenly distributed over a wide area. Cheap lights will have a spotlight effect. Very study mount (I ride 3' drops and this does not move) and easy to install. Battery life is excellent, as described by the manufacturer. I also use this as a flashlight for night walks - the shape is easy to carry. Highly recommend.

Me gustó mucho por la intensidad de la luz, en día lluvioso funciona perfectamente

Es una luz potente, rara vez la utilizo a toda su potencia, el modo de estrobo a pesar de que en la caja recoemiendan no usarlo de noche aqui en cdmx es muy útil al pasar por intersecciones.Los detalles solo son que la montura de la luz es un poco inapropiada para manillares gruesos por lo que cuesta un ratito montarla.

Un producto bastante bueno. Lo recomiendo mucho, sin embargo para la ciudad (CDMX) aún le falta potencia.

Queria una lampara con buena iluminación y a un precio accesibley esta en especial cumplio mis expectativas.Muy sencilla de montarse, y con buena iluminación para rodar de noche.

Tenía una versión anterior de este modelo, que funcionaba perfectamente pero que perdí cuando se cayó en plena vía rápida después de pasar un bache.El anclaje en este modelo está mejorado. Cuesta un poco más de trabajo quitarla para guardarla, pero ofrece más seguridad en terreno irregular. Por experiencia del modelo anterior, estas lámparas soportan lluvia densa, caídas y muchos ciclos de carga sin perder luminosidad. No tiene un indicador de batería, más allá de simplemente observar si la intensidad de la luz va disminuyendo.

Outstanding light. It attaches/detaches easily, has multiple flashing modes including blink and pulse, has a horizontally oblong beam pattern, and plenty bright for semi-lighted urban commutes.The only cons:- No removable battery- Takes a whopping 5 hours to charge from dead- Has useless side portsThis light is replacing my MagicShine 1600lm trail light. I do miss the crazy bright beam from the MagicShine, but it's a trail light and thus throws light in all directions - which means the same brightness could be achieved on the road itself by using less lumens in a more concentrated beam. This light does just that.Can't beat the price - just buy it.

This is an impressive light. I marvel that LED technology has progressed so quickly in the past few years. It's probably better than any one-piece light you could have gotten five years ago at any price. I bought one for use with a road-biased hybrid. Measured weight is 110g for the light and 32g for the included bar mount.It's powerful. The lowest setting would be ideal for walking around a campsite. The highest makes my capable Black Diamond headlamp from 2012 seem like a dollar-store flashlight. The beam dispersion pattern is oblong, a useful improvement over a more claustrophobic narrow spot. Blink modes are visible head-on in broad daylight, but don't have enough lateral feedback to replace side reflectors.It's durable. I took mine apart. The front plastic piece is robust and held on by three long screws; removing it reveals a battery encased in thick plastic and the LED assembly. Typical of 'name' gear and often lacking in knockoffs, the LED is properly cooled by heat-conducting paste and an iron backer. The lens ahead of the LED is a solid cone abutting the front plastic with a rubber waterproofing gasket. While the outer case will abrade if you drop it on concrete, I can't this see light ever failing.It's current-regulated. A lot of lights aren't (or they use an algorithm that allows for significant fade), so they'll dim as the battery voltage drops with use. There's a site called 'we test lights' that charts luminance over time for this light and Cygolite's Expilion 850, among others. This Metro 550 overachieves with 600 lumens for 80 minutes, then rapidly dims. The Expilion manages 800 for 20 minutes, then dims until it dies at around 2 hours. Between 60 and 90 minutes, it's actually dimmer than the Metro 550. The Metro 750 is similarly overrated; while properly regulated, it only has about 50 lumens and 10 minutes of runtime over the Metro 550.Mounting is a strong point. The metal quick-release mount is very secure, as is the plastic sliding release mount, though the latter is sticky and tight. You have to put pressure in just the right direction for the light to slide off. There's also a lateral swivel function I use frequently on bike paths to direct the beam away from oncoming traffic. Swivel friction is set by a single Philips screw in the mount.Controls could use improvement. There's a single, stiff, waterproof rubber switch. From off, a press-and-hold rapidly switches the light to the dimmest output. Once in this mode, tapping does nothing; you can only press-and-hold again to turn off. Short taps may or may not turn the light back on. Usually (but not always), you have to tap twice or even thrice, which will boot the light to standard brightness. (A long-press always works, but you have to time it right or risk switching to low.) Subsequent taps will cycle it through the various modes.There's no easy way to temporarily dim the output, so the only way to be courteous to people approaching is to cover it with your hand. The inconsistency of the tap modes makes it difficult to tell mode you're about to enter until you see the output. I often end up terrorizing someone with the blinking disco pattern by mistake.Should you buy this light?It depends how fast you ride. At a 10-15 MPH cruise, you could do nearly as well with 300-450 lumen Streak and Dash series. They weigh about 40% less and have 70% of the battery life at equivalent brightness. 300 lumens is plenty for safety and visibility at a running pace. The Metro 550's additional brightness is primarily in the form of a wider beam pattern; it doesn't have much more 'throw' than the others. To me, it's good to about 16-18 MPH. Past that, my gaze is too far ahead of the light's useful illumination. If you're a fast roadie on blacktop, you may well find yourself wishing for a more focused beam pattern.Mountain biking is a tempting use case. This light does have an inexpensive helmet mount, but there's no external battery input and it won't be bright enough by itself on quicker rides. I'd consider it an adjunct to a more powerful 1000+ lumen frame-mounted light. In addition to greater output, these lights often have a broader beam pattern that's more useful on a trail. Compared to the cost of replacing the bike or yourself from a wreck caused by inadequate lighting, this dual-light approach would seem economical.

Update:Consider getting the lower lumens versions of this light unless you really need a super bright setting. I believe the batteries are the same in all the Metro’s. That means the brighter bulbs will get you shorter battery life. And the only benefit of the more expensive higher lumens versions is if you need the extra brightness at the expense of how long it will last before needing to charge. I also posted an update with more details in the 600 lumens version. I’ve had 400, 500, 550 and 600 lumen versions and they’re all 5 stars. Great lights.Original review:I got these to "be seen" rather than to "see." I run two of these lights on my handlebars, each pointed somewhat to the side, to increase visibility to drivers approaching on side streets. To see the road ahead, the brightest mode is ample even at higher speeds (25 - 35 mph). The low steady beam is sufficient for others to see you on separated paths. The "steady pulse" mode is great for night traffic, but seems too obnoxious at night on separated paths or other places where other people riding and walking are nearby. I do run that mode or the flashing mode in traffic because I believe some pulsing improves visibility. The steady pulse mode is the brightest mode steady for one second then it briefly has a quick flutter, then it is steady again for one second, etc. I run flash mode (which flashes the brightest beam setting) during the day. Battery life is good, and re-charging is easy so there is no reason not to enhance safety by having these lights on every time you ride. Mounting brackets are excellent. Very solid, well-designed, and quick to remove when parking in thefty areas. The mount has inserts for older small diameter handlebars, and they are solid, and don't fall out, but can be taken in and out if you switch among bikes with different bar diameters. Beam pattern is round and fairly focused, but with generous "spillover" in the periphery for drivers to see you. I have run these mountain biking in the dark. It was amazing. As if the trail was in daylight. I have not much experience with night MTB so I can't say how they stack up to other lights for that. Running two of these lights for that was very helpful because it provided a wider area of bright illumination. Another nice aspect of having two of these lights (or some combination of two headlights) is if one runs out of battery then you still have safety / light to get home. Waterproofing seems good after several months of rainy commuting. For me the only "missing" feature would be a low beam flashing setting that I could use instead of the low beam steady mode on separated paths when I don't want to be too obnoxious to other people riding or walking at close range. With the good battery life, though, steady is fine. If you are tempted to think brighter (and more expensive) is better, note that manufacturers tend to offer a range of lumens with the fewer lumen lights being cheaper--but the batteries are the same, so the more expensive lights go brighter but don't last as long. Decide if you need that extra brightness, and only pay more for the brighter light if you do. For me, this light is plenty bright and the battery (unlike some smaller lights) is quite sufficient. Bottom line, great light, get two!

this light is very bright at night. good product
