    Winter night rides here we come! Really excited about this light. Sleek, study and bright!! Not only can ppl see me but I can see my path and I feel really confident when I am on the roads in the dark. Like being able to use different modes in different levels of darkness. Battery lasts long and appreciate the red light signalling low battery before it dies and I catch myself in the dark. Thanks Serfas!

    I bought 2 of these late in 2016 for some long distance riding, at that time the replaceable batteries were not available, after talking with the tech department they said I could tether them to external USB Batteries and they would run and charge at the same time !! this worked very well. These have been very user friendly and reliable, very light weight .

    Finally got to try it on a ride with two people out later than planned. He did not have a headlight. So, we both had to rely on my 950. It worked much better than any headlight I’ve ever used and got us home safe. The light pattern was perfect. Works with the same mount as other Serfas headlights. But, much much more substantial amount of available light than anything I’ve seen before—and I’ve seen and used many. Most amazing is the small size and weight for that much light. You used to have to have a separate battery pack to get that much punch. This is the headlight I’ll be recommending to all my clubs. A++ in every way! Serfas knocked it out of the park on with this light!!!

    Excellent light. I got the 950F as a replacement for an older light that was no longer working. I couldn’t be more pleased. Very bright light with excellent battery life, which yields excellent visibility when riding in the dark. I am using this for early morning, pre-dawn mountain bike rides where visibility is critical. I typically ride for two hours, and I’m typically in the dark for the first hour. I need to be seen by cars on the surface roads that lead up to the off-road portion of my route. I then need to see what I’m doing off-road so I don’t fall. This light performs well at both tasks. It is a *serious* upgrade to the 500 lumen light it replaced. I am also very pleased with the service and responsiveness I received from Serfas. Kudos to both the product and warranty teams for answering my questions and helping me out.

    I got the TSL-950F in the TSC-3 light combo. I can honestly say that this light is an amazing headlight for any type of riding. I take this light with me on any of my rides, day or night. The daylight flashing pattern is so bright, that I can see the reflection off of cars and signs that are much further ahead of me during the brightest days. At night, the steady beam spreads enough to allow the rider to see far ahead and to the sides as well. I charge this light once a week, and sometimes twice depending on the length and frequency of my rides. Also, the light has a light sensor that helps prolong battery life even more by automatically switching the light on and off depending on the surrounding lighting. I am using a different light mount for it, but if using the original mount, make sure to tighten it well to avoid unnecessary moving. In the end, these lights provide excellent lighting, batter life, and price point. I recommend it to anyone who rides a bike, day or night. I love mine, and I’m sure you’ll love it as well!

    This light is small, light, and powerful. A pedestrian was complaining to me to shut my lights off as he said it was too bright. Also, when I come up behind cars, 950 lumens seem brighter than what a car can produce. Now… most of the time, I am commuting in one of the less powerful settings. Quick Release HB clamp makes it easy to transfer between bikes. I would buy this light again and highly recommend it.

      Hi Brian, Great to hear our True Series TSL-950F is getting you some attention! We’re sure the pedestrian who complained would understand how awesome your light is if he, or she, was the one riding behind it 🙂 Thank you for your feedback and enjoy your light! – The Serfas Team
