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

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.

Excellent light for the price which is half the cost of the big G brand to match my rear radar/light & it also has more lumens. I run it in flash mode to be visible during the day. I haven't used it on a night ride yet. At some point I'm going to test the battery limit but I'm OCD so my items get charged between rides. I'm very glad they sell the 1/4 turn mount separately so I was able to get one for a second bike. It's not cool when you drive out of town and leave the mount on your other bike.

My son made fun of me until it got dark. Remote is cool but not quite intuitive. Mount fits the top of my helmet perfectly.

It is OK. On its own is not bright enough for full-speed rips in the woods. Having one on the bars and a helmet-mounted light to supplement it is essential. I am confident cars can see me when I am on the road but I don't like the light pattern. It is just a full-on flood and It should have more focus dead ahead. It has a wide throw, though. That is good for some situations for sure. I wish it had a focus setting. It can flash but its fiddly to switch from the flashing choices to the flood choices. It is two separate arrays as opposed to one list of all 6-8 types. All the flashes are one, and all the floods are the other. It is not cheap enough. the charger cord is too short. I like the clip mechanism and the fact that you can run it under the bars or over. The twist to lock it on is a feature I like. Seems to charge pretty fast Even though I am only using it for about 25 min 5 days a week, it has only needed about 3 charges in the last month and it sits outside at work for 10 hours in the freezing weather and rain and no issues killing the battery thus far. I hope it keeps up. I don't regret the purchase but I should have spent more and got more lumens or a verified amount. This seems low for 1200 and I bet my eyes that if you buy 4 of these 1200-lumen lights, no two will have the same lumens

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!
