TOWILD CL1200 Bike Lights for Night Riding,Compatible with Garmin/GoPro Mount,1200 Lumen Bright Bike Headlight,4000mAh Rechargeable Battery,Waterproof Bike Front Light for Commuter Cyclists

One thing that made me buy this light is that it doesn't make ridiculous claims about brightness. It claims to produce 1200 lumens at the brightest setting and that seems about right. I find the lowest setting of 300 lumens to be bright enough for most cycling unless I'm bombing down a steep hill or trying to stand out in brightly lit areas.The light is compact and easy to use. Press and hold to enter low setting, press again to cycle through medium and high. Double press to enter flashing modes. Double press to return to steady modes. Long press to turn it off. The button is illuminated to give an idea of battery level and charging status.The mount is well thought out. It can use a GoPro mount or a Garmin mount. It comes with both and a handlebar mount too.It has a shaped lens, like the expensive German dynamo lights. Most battery lights have a perfectly round beam that gets brighter in the center. This is not a good shape because the bright center washes out the road near you and prevents you seeing anything further up the road. You need a beam that gets brighter towards the top (because the top hits the road further in front of you) and then cuts off so you don't blind oncoming traffic. This light does that - not as well as an expensive dynamo light - but better than most battery lights. Because the beam is shaped, you can't just turn the light upside down. But if you want to hang this light under the handlebars or under your head unit, you can flip the light in its mount so it's still the right way up. This is very important and it shows the designers knew what they were doing. Thumbs up to the engineer who told marketing this has to be a feature.I have a GoPro mount on my helmet but I thought this light would be too heavy to put on a helmet. I recently rode a hundred miles with it up there and it was just about OK. So there's another mounting option.Summary - bright, easy to use, great mount, shaped beam, and a reasonable price. Really nothing negative to say. Five stars!

In my opinion, the obsession with the brightness (lumen output) of bicycle lights is overrated as the primary measure of the 'quality' of a light. Brighter is not necessarily always better. What is important is how well the beam lights the road in front of you. Most domestic (USA) bike lights are essentially flashlights with a handlebar mount.This light has a maximum output of 1200 lumen, but the more importantly it has a shaped beam that puts more of the light on the road. It conforms to the German StVZO specifications which requires that the beam cut off on the top end to avoid dazzling oncoming traffic (cars, other bikers, walkers/runners). I think this is very important--especially for lights with a high lumen output. By focusing more of the beam on the road you get more bang for your lumen buck and fewer expletives hurled at you by startled oncoming drivers, bikers, or pedestrians.In some circumstances, the best reason to get a very high lumen output light is to achieve extended run times in lower output modes that are adequate for most riding conditions. For example, the Towild CL600 (600 lumen max and smaller battery) has a claimed runtime of 1 hour 30 minutes at 600 lumens or 2 hours 30 minutes at 300 lumens versus the claimed 3 hours 30 minutes at 600 lumens or 6 hours 30 minutes at 300 lumens for this model. You get more than twice the run time on very useful output settings for less than twice the cost.Since this light has a shaped beam, it is important that it is always mounted right side up. The mount can be flipped over with the supplied hex key so that it can be handlebar mounted (included) or attached to a GoPro compatible out-front or helmet mount adapter (See update at end), but not the mount included). It attaches to the mount using a Garmin style 1/4 turn so it is easy to remove the light from the bike for security. Those who complain that the GoPro mounting screw is not included with the adapter should note that the screw is generally included with the mount which is threaded to accept it.The lowest setting (300 lumen) is fine for riding on city streets with streetlights. The medium (600 lumen) and high (1200 lumen) settings are good for paved trails and streets. If you need to watch out for debris/potholes or ride at higher speeds on unlit roads or trails, stick to the highest setting. As a test, I took it on an unlit paved trail near my home. While not as bright as my dynamo powered B&M IQ-X, I felt comfortable at about 15mph with the light on medium (600 lumens). I found this light to be more useful at 600 lumens than another at 700 lumens that had a wide, undirected beam. Regardless of the conditions and light output setting, be smart and supplement your lighting with reflective clothing when riding at night!I bought this light primarily as a daytime running light. The day 'warning' mode is plenty bright with a 4 flash/pause/2 flash pattern. The night 'warning' mode runs in a constant low mode with an intermittent bright flash.The claimed battery life on high is 1 hour 45 minutes. In a test, it lasted over 2 hours on high before it went into the 10% warning mode. The recharge time via a USB-C input (short USB-A male to USB-C male cable included) was about the expected 4 hours. The light can be used with an auxiliary charger on its lowest steady setting or either of the 'warning' modes to extend the runtime. It makes sense that the higher output modes are disabled when it is attached to a charger because the charge time is longer than the expected runtime. It can also be used as an emergency backup battery for your phone or bike computer. A USB-C to USB-A female adapter is included.There is a single switch to control all of the light's modes which also has an integrated led to indicate mode and charging status. Various short/long click patterns are used to switch it on/off or to switch the brightness or steady/flashing modes. A little confusing. The remote has dedicated buttons for this so it is helpful (see below).It can be programmed to automatically go into standby mode (off) after 2 minutes stationary and automatically turn on when movement is detected. The indicator led is blue for 'smart mode' and green for manual (on/off) mode.When charging, the indicator is solid red with a full charge being indicated by solid blue or green depending upon whether the light is currently programmed for smart or manual mode.The indicator light also displays the charge level while in use: 100-30% = steady blue or green; 29% - 10% = slow flash blue or green; less than 10% = blue or green alternating with red.Miscellaneous notes: Hot to touch when in high mode (there's a warning on the body). Solid construction and materials. I think it will stand up to its water-resistant rating so long as the charging port cover is in place. It returns to the last setting used (brightness or flashing) when turned back on.Only a few complaints (not worth a star reduction in my rating):1) The instructions (especially for the remote) are terrible because they were clearly written by someone who is not fluent in English (e.g., the use of the term 'gears' for 'modes' and lots of awkward phrasing), but with patience you can figure it out.2) I would prefer a 4-step indicator for charge status (e.g., 100%/75%/50%/25% with a flash and/or red warning at about 10% or less).3) The single switch operation is confusing and hard to operate while riding. The remote is a good option to get around this. It has three buttons: 1-Off/On (long press) brightness level or day/night warning mode toggle (short press); 2-Steady/Warning mode toggle; and 3-turns on the high, steady beam while being regardless of current running mode.4) The remote can turn the light off, but it will not turn it back on unless it is currently in smart mode, standby state. A bit of a pain, but it makes sense that keeping the light in a constant standby mode waiting for a remote command would slowly drain the battery.5) Pairing the remote to the light was not intuitive. However, as noted above it makes the light easier to operate while in use.Despite these few complaints, I am happy with this light and recommend it.Update: the included plastic GoPro style adapter is not very sturdy. It cracked and I had to replace it. I am still very happy with the light itself.

Great simple little light, I have the 1200 with the 4000 mAh. It only has 3 settings, but it is all I need for night riding. I rode a few times with it, and it provides plenty of lighting, even at the medium setting, with a good light beam in front of the bike. A blinking setting would have been nice for day riding. The battery appears to last as stated.It is easy to operate with a back-lit switch that turns from green to red when the battery is down to 30%. It would be great to have a battery percentage reserve indicator instead of the light turning red. This means that when the light is green light can be anywhere from 100% to 31% and I can't know if I have enough for another ride. This is no big deal but you know we sometimes forget to charge our stuff (Phone, Computer, Back light/radar, Shifters, PM, etc...)The light itself is solid with an aluminum body but everything else is plastic, it doesn't feel cheap, you just need to be careful to not over-torque during the install. There was some play between the light and the u-shape bracket that holds the light, so I put a small piece of duct tape between the light and to bracket to fix this.The supplied holder is easy to install, it holds the light securely, the light also works fine my other Garmin holders. I have the remote, but I haven’t tried it, I may use it if I decide to put the light below the holder on the road bike. On the gravel bike it works well on top of the handlebars.Overall, a great value, highly recommended.
