20W High Power 2000LM Led Motorcycle Headlight Lamp Motorbike Led Spot Light for Street Bike Bicycles Motorcycles Motorcycle Rider Cars Trucks Boat Using

Very bright at 36V. Small, light, and bright. Seems well made. Very pleased so far.

This is a great light. The bracket is a bit cheap looking, but it mounts solidly and it does not vibrate on my gravel roads. This thing really throws a lot of light - and heat! Holding my hand 12" from the front, I can feel the heat! That makes me worry whether the passive cooling fins will be enough to keep it running long-term.Someone asked if this is waterproof... I'd say the LED portion may be, but the housing itself is not. The cheap 90° metal bracket that is held to the aluminum housing by two screws, is the actual back cover. There is no seal between the bracket and housing. In fact, 95% of the inside is empty with just the very front portion being used for the LEDs and circuitry. I suppose that is for the heat dissipation requirements.In any case, the cable that comes with it is way too short. Unless your ebike controller is mounted on the handlebar, be prepared to splice additional. My controller is in a under-seat bag - so I had to add about 3' of cable. Rather than have a splice 10" from the light, I made the splice inside the light housing and used a cable of the same size and type as the OEM. It looks just like the original, and it reaches the controller. If you're handy with solder/head-shrink tubing, this is a pretty straight forward mod.Overall I'm very happy with the performance of the light. In fact, I'm a bit concerned that on-coming traffic may find it blinding.

This headlight looks decent and is plenty bright for navigating unlit streets. It accepts a wide range of voltages so it's simple to add to an e-bike or scooter. One minor cosmetic annoyance is the LEDs are not rotationally clocked at a perfect 90 degrees but slightly off from it. Doesn't affect performance. I cut and drilled the mounting bracket so I could clamp the light under the stem and it works great.

Using an ebike's 48v battery as the input to this headlight, it's the brightest thing I've ever seen on a bike; this thing is so bright at night that the stock headlight on my ebike isn't even visible (it's completely drowned out). It's really almost as bright as car headlights, as far as my eyes can tell.Excellent brightness combined with a great price, as well as the simplicity of installation -- i.e. nothing but positive & negative input wires (it's either getting power and is on, or it isn't getting power and it's off) -- makes this a winner in my book. It even has a wide range of compatible input voltages. It's absolutely perfect for my purposes.

The light is dencently bright, but only 10 minutes of 80v and it was getting dangerously hot. Over 150 degrees fahrenheit, which is really hot to the touch.

I wired this direct to the power feed to a 36 volt ebike motor from the battery. I comes on and off with the key. I use it mostly for daytime safety, but it's strong at night. Very, very bright. I have two bikes and sometimes my wife falls behind. It used to be tough to pick her out in my rearview, but with this beast I can easily see her 300 yards away in the bright Florida sun!. I really like this light. I have it mounted on the fork brace so it bounces up and down a lot. So far it has taken a beating, but still working good. I bought a second one and put it on my bike. We ride 4-5 times a week for an hour of so. Some people mentioned a frail power wire connection on the circuit board so I took my lights apart first to see if it was secure. Looked like the manufacturer listened because the connection to the circuit board was nicely secured with silicon adhesive over the soldered joint. As long as I had it apart I put some silicone grease on the threads and the face of the housing where the lens screws on. Couldn't hurt to supply a little more water resistance here. Heck even if it lasts a year will happily buy a replacement. High voltage ebike lights that throw this much light from the foo foo brand companys cost 10-20 times as much.

UPDATE: After 6 months of riding on my eBike, mostly without rain it has died. It seems water got into the light. Very cheap, so expected, but still annoyingI wired this into our 72V ebike and it is super bright. At night it is seen .5 miles away, and illuminates the road well plus is visible in the day. It is a bit narrow of a beam, but very happy with the bracket that holds it steady. You do need to have minor electrical skills to strip and solder/ connect this wire, but very happy with it's brightness.

Updated my lights for 97 express, looks good too.
