Serfas USL-TL80 USB Tail Light

Serfas USL-TL80 USB Tail Light

The Serfas TL80 is a high-powered, compact, USB rechargeable tail light that will keep you visible from more than a mile away. The TL80 can be attached to just about anything and features an angle-adjustable mount to put on your frame or seatpost. Serfas tests all their lights in house on their traceable integration sphere to ensure measurements in lumens, run times, color temperature, and lumen curves are measuring correctly during each test run. As the name infers, you’ll get a true 80 lumens for up to two hours of riding; it then automatically switches to the low setting for the remainder of the battery life. Serfas Lights are RoHS compliant, which means that Serfas does not use any environmentally harmful products in the production of their lights. Choose a brand that cares for the earth.

Ride With Confidence
I was looking for a versatile, USB rechargeable, high illumination tailight, and did some homework before purchasing. I use the light for my daily commute on my e-bike, and on my road bike. So the light is used daily; 1K miles the first month. The light is everything it was advertised to be. It is very bright, the brightest in my night ride group. So bright that I was asked to turn it down when it was on the low setting. My advice would be to angle the light down towards the pavement if too bright in a group setting. Otherwise that intensity is perfect. I also use the light during daytime rides -- it can't hurt to be seen and it is visible, even in bright sun. The transition betweeen bikes is a breeze thanks to the notched stretch band used to secure the light, and the light is angle adjustable (without tools) to account for different seat tube or frame angles. The switch is very sure. I can confidently activate the light while riding, using a gloved hand. If I had a complaint it would be the fact that the unit is limited to four modes, low, high, and two flashing. Overall, the best light I have used and would certainly recommend it.

Battery life is quality and brightness is beyond belief. Jesus or any biblical character would use this light. Only issue is when placing the charging cable into the light as it can break if your over zealous. Treat it like a super model and your rocking.

CONS: Weak

BEST USES: Long Rides, Road Bikes, Commuting, Mountain Bikes

Bright light, weak design
I bought this for night mountain bike rides. It's very bright, but the seat post attachment isn't very strong, so the light jiggles around. I've used lights with much better designs for a fraction of the price of this one. I'm on the fence about returning it.
