Muy buena iluminación para mí bicicleta

Faretto molto solidoFacile da montareMolto potenteBatteria duraturaFacile da montareOttimo rapporto qualità prezzo

Linterna buena y potente, excelente calidad. Después de un año y medio de uso regular mi experiencia es totalmente positiva. La duración de la batería es más que suficiente tanto para una salida nocturna larga como para varias más cortas, y la carga mediante USB muy cómoda y versátil. El sistema de anclaje es firme y muy fácil de usar, nunca me ha dado problemas. El alcance de la luz es grande y la potencia muy buena, tanto en ciudad como en lugares sin ninguna iluminación. Proporciona un amplio rango de visión y resulta muy visible para otros vehículos (en ocasiones hay que tener incluso algo de cuidado para no deslumbrar). Ningún problema tampoco circulando con lluvia. Es muy útil el sistema que te avisa de que queda poca batería, y los distintos modos de iluminación (mediante flashes) también pueden resultar bastante útiles dependiendo de la situación. El trato del vendedor es excelente, la comunicación rápida y en caso de duda o que surja algún inconveniente responde perfectamente y aporta soluciones satisfactorias. El servicio de garantía post-venta también es muy bueno. Recomiendo el producto, la atención al cliente y lo volvería a comprar.

I just got this bike light today. Here is my first impression.Size - For some reason my brain imagined this thing to be about twice as big as it really is. It's just slightly longer than the palm of my hand and about 2 fingers wide. Each lens / reflector is only about 5/8" in diameter. This will easily slip into a pocket or a backpack.Weight - Based on other reviews I expected a fairly hefty little light and that's what this is. There's a metal housing along with 2 LG-18650 lithium ion cells and the electronics. It's a densely packed little chunk. But it's not unreasonably heavy given the specs. It feels like a quality product.Looks - It looks very "industrial" but clean and functional. It's not some piece of industrial design art destined for Museum Of Modern Art and priced accordingly (I'm lookin at you Apple). It looks like it's meant to take a lickin and keep on tickin. And that's fine for me. Design, materials, and assembly all seem to be high quality.Ergonomics - The simple design extends to the mount and the controls.- The mount can be installed an uninstalled without any tools.- The light clicks into the mount smoothly and securely.- The light can be released from the mount with a button push but it's a 2 handed operation.- Theft should not be a problem if you take 5 seconds to pop the light and/or mount off your bike.- The light can be pivoted up/down by loosening and tightening the mount.- The light can be pivoted left / right using detents built into the swivel mechanism that click into place.- Controls are 2 pushbuttons. On/Off + Mode. They are rubberized, easy to find and have decent tactile feedback.- On / Off = long press- Mode = Fast press to cycle through settings. Long press to switch modes.- An average person should be able to figure out the controls in seconds. Simple is good. Simple is elegant.- It's smooth and there's no texturing but it's small enough to grip securely. I don't envision accidental drops being a problem.Charging - There's a rubber cover on the bottom side that protects a micro USB connector. A spare rubber plug is also supplied. A USB to micro USB cable is included. Just plug into a computer, a phone charger, a 12 volt car adapter, or a power bank. Simple.Modes - There are 2 modes. Switch between them with a long press of the mode button.Mode 1 = Default. The settings you can choose are Low, Medium, and High output. Mode 1 will always be the default start up mode and the light will remember the last setting (Low, Med, High). There is no "Ultra" or "Micro" setting as shown in the product listing. Just a basic 3 settings Lo, Med, Hi.Mode 2 = Requires a long press to access and there is no memory feature here. Unfortunate because this is the mode you want to be in all the time. The 6 choices here are Low, Medium, High, "Turbo", Strobe, and SOS. I'm not even sure why they created 2 modes. Just give me Mode 2 as a default and I'm good.Light Output - Very good. Perfectly adequate. About like a good HID car headlight. But not beast mode. And that's fine for me. But when it comes to actual quoted lumens for any of these Chinese lights.....well.....take the claims with a grain of salt.None of them actually tell you the specific Cree LED they are using. Some of these lights claim to be using 2 of the older XM-L design in a T6 bin LED and they claim 2400 lumen output. That's hilarious because Cree specifies a 330 lumen output for that part. So the most they could reasonably achieve is 660 lumens with 2 LED's.This light claims to be using 2 of the newer XM-L2 parts but specifies no bin number. At any rate the XM-L2 maxes out between 700 and 780 lumens according the the Cree spec sheet so even 1870 lumens claimed is doubtful. So don't get hung up on numbers you can't validate. Just know that this light is plenty powerful with a well designed beam for any reasonable speed.Low = 15 Lumens. A reasonable setting for close up use when the light is off the bike. Think of it as a low powered flashlight for digging your keys out of your backpack, etc.Medium = 180 Lumens. Moderate output. I consider it more for "being seen" than lighting up the path ahead.High = 850 Lumens. The workhorse night mode. This is the mode yer gonna use 95% of the time at night. I'll explain why in a minute. But this setting produces plenty of output in a spread that is about 50 feet wide at a 50 foot distance. It provides enough forward vision at enough distance (~100 - 150 feet) at any reasonable speed. If you're cranking downhill at 40 mph in the dark.....well.....good luck to you. Moving up to the High setting doesn't actually get you much better forward or side vision."Turbo" = 1,870 Lumens. Yes it's higher output than High. But it doesn't really result in better lighting of terrain or greater distance. And here's the kicker. The info sheet that's in the box discloses a nasty little secret. The high output setting has a 5 minute time limit. It seems there's a thermal management system to prevent the LED's and batteries from cooking themselves. And that's a good thing. But because it cuts battery life in half for not much better lighting, I consider this an advertising feature only. It's pretty much pointless.Strobe = 850 Lumens. This is gonna be my "go to" setting for daylight riding. This is great for attracting the attention of oncoming traffic or cars at intersections, etc. in broad daylight, dawn, or dusk. I wouldn't use it at night because it may blind or confuse people. Not so great for the person using it either as the strobe can screw up your night vision.SOS = No output given but I don't really care. I can't envision myself needing to use Morse Code. Another goofy feature. I'm guessing it's probably using the 850 Lumen "High" setting.Battery Life per the advertising.......Low 15 Lumens - 76 hoursMedium 180 Lumens - 32.5 hoursHigh 850 Lumens - 7.5 hoursTurbo 1,870 Lumens - 4.5 hours (LOL, 5 minutes at a time)Strobe 850 Lumens - 8.5 hoursI find this totally acceptable. Both the High and Strobe settings provide about 8 hours of run time. My typical recreational ride is about 12 miles / 1.5 hours. That gives me about 5 days of use on a single charge. The battery cells are a good quality LG battery. I expect decent performance and battery life.Other stuff to consider..........Aiming - Do not point this thing straight and level. You will blind oncoming traffic. Yes, it's that powerful! I found that pointing it downward about 15-20 degrees achieves 2 benefits. First, you're not blinding the guy in the 4,000 lb car driving towards you at 50 mph. Second, it really improves the beam pattern on the ground in front of you by taking the hotspot in the center and making it a long oval instead of a round circle. So instead of lighting up the trees with that hotspot, you put it to work where it will do some good.Beam Spread - Others have said the beam spread could be wider. On the light I received, the beam spread (when properly aimed) is huge. I'm perfectly happy with the beam width. It is way wider than any trail I've ever seen and wide enough to cover a 2 lane road at about 30 feet. Unless you're planning a night ride on a 4 lane highway, I can't imagine needing more beam width. I think they nailed the width to distance tradeoff in the design.Value - I paid $50. I know there are lights that cost $400. But I don't know that the extra cost would give me more usable performance, reliability, or durability. This light gets the job done very well in daylight and darkness. The value here is excellent.Hope this helps others looking for safety equipment.

Sturdy build and good light power. Only downside is that it is very heavy. There is a weight price to pay for battery life.
