    It’s a great light, however, I have a wireless computer on my bike and when I turn on the light…the computer stops working.

    • Serfas

      Hi Dave, Thank you for your feedback. The situation you have described indicates an EMI (Electro Magnetic Interference) scenario between your wireless computer and our high-output headlight. This can occur when electronic shielding in either device leaks these invisible signals. Our recommendation is to relocate the light and/or computer far enough away from each other on the bike that interference no longer occurs. We apologize for the inconvenience.

    Wow, Just got it but so far am truly impressed.Commute to work in the dark morning and ride home when it gets dark, with no pun intended this is the brightest part of the ride. Bought a Lumina 900 and battery life was subpar and not a very good pattern. Rode the 1600 e-lume on high thinking it was on overdrive until I pressed button and all I could say was Wow

    Same light from is only $40. I have been through three in the last 9 months. Pretty much just cheap Chinese junk. Buyer beware.

      Hi Josh, Thank you for bringing this to our attention. Our Serfas lights are high quality products manufactured to meet high performance standards. Our Product Development Team tests our lights in-house to make sure they meet, and often even surpass, performance expectations. It is unfortunate that because we offer such a successful and high quality product that sub-par imitations are occasionally found outside of the United States market using lesser quality components and lower standards of construction. We are sorry to hear about the three imitation lights that failed on you and encourage you to try a genuine Serfas USL-1600 E-Lume light! – The Serfas Team

    Forgot my helmet mount on a night ride and my old bar mount headlight was not enough. When I was able to hold my pal’s wheel I was so impressed with his Serfas light (and in the dark as soon as I got dropped) I had to get one.

    Construction is rock solid and form is attractive comparing to my Nite Rider and Lezyne lights, not to mention it’s bright as you need it and the battery will probably outlast your night riding. I like the on/off button timing too — minor detail but some buttons need to be held awkwardly long or turn on accidentally without a hold function.

    The bar mount is adjustable for different diameters, and the clamp is, in my experience, the easiest to mount/dismount, and then it’s absolutely glued to the bars. So much so that you’ll have to unlatch it to make small pivot adjustments. At 240g it’s reasonably light enough for helmet mounting too.

    Look no further for a mountain or road headlight!

    This is my first light for my new addiction of winter fatbike night riding…..or I should say with this light its daylight riding even at night. Absolutely amazing light, length of battery life is very impressive. As Jeff mentioned above your mount is crazy good and strong, well done on this product…..worth EVERY penny spent for this baby.
