Garmin's Varia UT800 Smart Headlight is penetratingly bright and versatile. At its highest setting, this mountable bike light shines at 800 lumens and provides 270 degrees of visibility. The Varia UT800 has 5 manual modes of operation and smart auto-adjustability based on speed (higher speeds trigger a brighter beam) and ambient lighting (well-lit environments trigger a softer beam). In turn, these automatic adjustments help conserve the battery for extended use between charges.

Lightweight and highly water resistant, the Varia UT800 can be used in all kinds of conditions: rain, snow, and it can even withstand occasional splashing. This smart headlight syncs to Garmin Edge computers, remotes and light sensors for greater versatility and ease of use.


In the box:

  • Varia UT800 smart headlight.
  • Hardware included for a helmet mount ("Trail" version), or an out front mount ("Standard" version).
  • Charging cable.
  • Manual.

Dimensions (LxWxH): 96.6 mm x 33.5 mm x 29.7 mm; 44.7 mm with flange; Weight:130.0 g.

Garmin has put out a finished great product this time.

After 6 month of use i really like this product. The only thing I could knock would be light adjustable angle pincher screw mount. Sometimes when going over rough road the light will loosen and change angles. I do not want to over tighten it do to the mount is plastic. Garmin should go to a grooved lock design that will stay put.

Great light

This light works amazingly well with the Garmin mount allowing the installation of the light under the computer and not on your bars taking up space. That said even though the light comes with an upfront dual mount, that mount places the Garmin Edge (1030 in my case) too high above the bars. But that might be as well a matter of opinion. I purchased from BTD the Garmin Out Front Mount (Edge 1030) Part Number 010-12563-00 and that places the Garmin at my preferred height flush with the bars. Pairing the light with the Garmin Edge is a snap and very easy to operate while riding as far as changing from the various settings. Highly recommend this light.

Excellent Light

Ive used this bike for about 1,000 miles in sunshine and dark morning rides. First the good, it is compact and mounts well to a GoPro style mount well. I have had to really synch it tight to keep it from slipping down when I hit bumps but as long as I do it works great. The beam at night is really bright and the road is well illuminated I can be seen and see very well. In daylight I use the flashing mode to be seen and to conserve battery. My riding buddys tell me its really visible from a long distance and the flash mode Really catches the eye, which is why I bought it and use it every ride. switching modes manually is reallyeasy with the large tactile button. My rides are 2-3 hours long and I have no battery problem with 1 hour steady and 2 hours flashing. I have not syncd with a cycle computer as mine was not compatible, yet. It takes a while to recharge and once fully charged slowly discharges over time. I charge mine after every ride and if I go a couple of days without use it will lose about 30% of its charge so I have to top off the charge the day of ride if I plan to go long. Hence the 4 not 5 stars. all in all, I would recommend this light.

Great light that works wth Garmin

Run this light on my road and gravel bike. Easy to sync with my Garmin and like how the speed effects the brightness of the light saving power. I run it in flash mode during the day and its bright.

Excellent light

Easy to attach to the Garmin computer dual mount without taking up space on the handlebars. Also, very easy to turn on andor adjust mode while riding. It has a reasonable operating time before required recharging. It is also water-resistant as I found out when I was caught in a rainstorm. The headlight continued to function properly while my taillight (another brand) was not able to handle the deluge. However, the Varia is more expensive than other headlights of similar wattage.

Bright, convenient, good battery life, takes up no room on your handlebar

The best thing about this light is that it doesn't clutter your handlebar with another gadget, but fits under a Garmin in a dual mount. I don't ride at night, but went to Europe and felt comfortable in the long, dark tunnels.

Good, not great

Nice beam, but there are some Bontrager and Light & Motion lights that have better ones. Good battery life, but when you use the smart life features the battery can burn through in 1.5 hours or less. Not incredibly expensive, but also not a great deal.

Look elsewhere

On its highest setting you'll be lucky to get 45 mins of light. Probably less. But wait there's more... when you sync the light up to your Garmin cycling computer using the smart technology be prepared to have the cycling computer completely freeze up and require a factory reset. That's right..... you'll need to re-program all your screens, personal data, etc... On the plus side, it looks nice.

Great light when combined with head unit

I have the light mounted to my helmet using a GoPro system. The light works well and the battery life has been very good. When connected to a Garmin head unit, the light will turn onoff automatically and will get brighter with speed. Light coverage is good for the trails I am riding. I generally have a light on the bars plus this one on the helmet.

Wonderful light

Garmin makes pretty good products and their UT800 is no different. Its bluetooth compatible and you can hook it up to your existing Garmin Edge device for connectivity. Its baytery life is pretty good lasting around a couple of hours on the solid beam section. I have this parked with the Garmin Varia and they work well with one another. Hopefully their next iteration the light will be better.

Convenient and bright light

The road bike version of Varia 800 comes with dual holder for garmin gps and light. Easy to assemble and has settings for night riding to bright flashing for daytime. My only complaint and its not against the light so much but the blue tooth is interfering with my garmin 810. Its not supposed to work with the 810 but its causing pauseresume issues as its tryng to connect.

Excellent Light - Well Made - Long Battery Life in Flasher Mode

Love the style, mount and workmanship. Mounts on the bottom of my Garmin mount. I used a 1030 in top and it connects to the light. I use the light in flasher mode to be seen during the day by motorists.

best light out there!

This is a great headlight. the mounting to the underside of the out-front mount is fantastic as it removes connections of gear on your bars. The connectivity to my edge 530 is awesome. turns on automatically, adjusts the beam intensity for speed. Combine this with the Garmin rear view radar/tail light for the best possible set up. I thought this light was so good that i bought one for my wife as well. looks great. The windows which provide light to the sides is a great feature for visibility.

Very bright light, long battery life, variable intensity and flash.

I'm 72 ride 18 mph in Pa. mountains and hills 50-90 miles a week. It's heavy, not sure of the weight but heavier than my last light. It is very bright, the mount allows for my Garmin computer to mount on top and aim the light downward so as not to blind on coming drivers. Don't want to give cyclists a bad name..but I can reach down and pull it up if someone is pulling out or not watching out for me. It gets their attention quickly.
