Great light, narrow focus. Being a night rider i have two of every light, my safety depends on being well lit. I bought another brand as my backup helmet light because it had a tail light but the beam was too broad rendering it a "˜be seen' light not what you want in a helmet light. This one works well even on low power. I'll order another as my backup.

Bought one for me and one for my spouse, both the 1000 Lumen series.
Experience: I ride my bike 100+ miles a month, she rides 1000+ miles a month.
Short review: We both love these lights, would recommend completely!
Long review: VERY bright - as bright or brighter than my car headlights. Have not seen another bike light that is brighter.
Compared to other bike headlights we have owned, or seen on other's bikes, and we have seen/used many - I would say there is none better - especially at this price!
Over the last three months we have used them for many rides: day, early morning, late nights, and one relay ride that went overnight. We also use for walking after dark.
Lots of settings for day/night and steady or flashing options!
One single "˜power button' is easy to operate on and off; it is also the button to switch between settings.
When you take this out for a ride and see the light bounce off of street signs and reflectors FAR in front of you, you may be as shocked as we were because of how powerful these lights are! Nice white light gives good color reflection and visibility.
Battery life through several charges seems to be as described in the product descriptions and manual. Satisfied with charge and life of battery in use.
We tested these lights to battery-shut-off, a few seconds later hit the power button again - got a few more minutes (was able to do this a few times). We have found that these will hold full charge or close to full charge for several days if not in use - haven't really let it sit out of use for more than about a week.
Light will get warm when on - most notably when on highest power. Ours have never got too hot to hold in a bare hand, even for extended times.
The supplied mount is sturdy, stays put on the handle bar. No issues with breaking pieces or slipping mounts. Very easy to install, no tools needed. Mostly simple to put light on and off of mount. Locks in securely - we have not had light come off once on a ride. Sometimes is slightly stubborn to remove, but I need to try the lube idea from another review to see if it makes it a little smoother to take out... not a big deal, and certainly no more difficult than other bike equipment we use.
Have not used the go pro mount, but excited to buy and give it a try in the future to mount to helmet or head strap.
CECO-USA, if there is anything we could recommend to improve to your light compared to other bike lights we've seen or used- it would be adding an indicator light on the unit for battery life; such as different power button lighting colors or small lights to help indicate full battery, 50%, 25%, almost dead.... that would make the light about perfect! Not taking away any stars for this, as there is a flashing of the light that indicates when the battery is getting low - just think another indicator system would be nicer.
After purchasing and using these lights, we have decided to order two styles of the rear red safety lights from this same company to replace existing rear lights we want to improve. We hope we are just as happy with those when they arrive!
My wife and I would recommend this light as a "˜must have' to anyone for day or night safety on bike rides. Also great for outdoor walking in dark, or even a flashlight for camping, at home projects, or power outages... it's light weight, and a good size to hold comfortably in hand. It's my go to equipment anytime I want to use a flashlight better than the one on my phone.
This light does not adjust to your speed or level of light in your environment, we've seen lights that do that - we don't really care for those features. We appreciate that this one is straight forward and cost effective with a simple design. Overall for price and function - it's the best light we've seen for bikers! If you need a bike light, this one works, and works well!

This is a heavy duty aluminum bodied light. Good build quality. Also, unlike so many others on the market, it does not inflate it's lumens claim for brightness. The only issue is the mounting mechanism is a little fussy. Not particularly hard to mount, but if the cord is not tight enough when secured, the light will move up and down on rougher surface roads or trails. Need to really tighten as hard as you can. Otherwise, an excellent light.

Excellent. Battery life is adequate. Would be nice if battery replacement were possible but at this price point this is good enough.

I have gone through several cheaper lights trying to find the right affordable solution for night time commuting and found every single one of them in the ~$20 range either disappointingly dim, poorly constructed, or just plain broken on arrival. I wish I had just saved my time, increased my budget a bit and purchased this first.

This light is high quality, bright enough to illuminate the whole road (and at top brightness probably even be mistaken for a motorcycle by motorists) and has a heavy duty rubber strap that I personally prefer over other, more permanent mounting solutions. I like that I can easily swap it between bikes or pop it in my bag when I go into a store without worrying that I'll return to my bike and find it missing. Its direction is also adjustable with a screw so if you keep your cables tight on your handlebars leaving you with no flat mounting surface you can tweak it by degrees until it looks straight ahead. Very cool feature!

If I had one small complaint it's that at full power it doesn't hold a charge for long, around an hour or two, but that's the tradeoff for not getting a light with a clunky external battery and is more than enough to get through a commute or nightly workout ride without issues. Just remember to pop it on the charger when you get to the office or get home. It's even got a handy flashing light under the power button to tell you when it's running low so you won't forget.

I love this light, I expect to use it for years to come. Highly recommended!

UPDATE 06/2023:
I've had this thing for 2 years now, put thousands of miles on it and it has never failed me. It does suck up juice if you use it at its highest brightness, but this is comparable to a car's headlight and total overkill for all but the most intense weather and traffic conditions. 5 Minutes of charging from dead will get you 30+ minutes of low power flash mode. Toss a small power bank in your saddle bag and you'll never ride without light.

I love this light, I plan on buying another 2 or 3 to keep new in the closet as backup in case of emergencies, I never want to go on a ride without this light again.
