Garmin Varia UT800 Smart Headlight

Fantastic light. Very bright for daylight use and many useful modes to apply. Highly visible in daylight so perfect for safely being seen. Very rugged, I didn't connect it properly and it was bounced off skittering down the street. Took the fall well with barely a scrape and functions fine. Holds charge very well and easy to charge. Your run time will of course vary on mode used but I get over 10 hours in intermittent flash mode charging every 3rd ride or so with battery remaining. Love this light!

Impressive light. You have full control from the head unit, which can set the light to automatic. Ambient light sensor takes care of this - as well as fluctuating the lumens based on your speed to get the most out of battery life. Another very well thought-out Garmin product, just wish it wasn't so heavy... but that's just battery tech for you. Highly recommended either way - completes the ANT+ light network with the Varia RTL515 when used with a Garmin head unit. Game changer for cycling safety. Recently replaced my conventional front light and couldn't be happier.

Bought this headlight to integrate with my Garmin Edge cycling computer and replace a Niterider headlight that I'd been using for a number of years. The construction and light strength is every bit as good as the Niterider and the fact that it plays nice with my cycling computer (along with a very intuitive app) is a big plus and the main reason I bought it. It also attaches to the same mount as the computer, meaning more space on my handlebars due to one less clamping mechanism.

The light works seamlessly with my Garmin Edge 1030 Plus, with effortless connectivity. The Garmin Varia UT 800 provides exceptional brightness making me feel much safer and the battery life is excellent. It is very easy to use.

This headlight is very good. Garmin allows you to pair it with your Edge cyclo-computer via ANT+ and set up a "Light Network" which allows you to control your lights via the cyclo-computer, including battery status. However, creating a Light Network causes the light to continue to broadcast ANT+ even after you have turned it off. This causes the battery to drain and the next time you ride it may be dead. You don't have to use the ANT+ and then it works just like any other light, and the battery lasts a long time, especially in flash mode. When/If Garmin fixes this issue, the light will stand out over similarly spec'd lights

I was excited to add the Varia Headlight to my Garmin/Varia rig. I purchased the light as a safety light rather than for night riding. My typical ride is about an hour to an hour and a half with much longer rides on the weekends. However, I am disappointed in how long the battery lasts, about an hour, even at the lower setting. Pairing the light with my Garmin 540 took a bit of work and seems to "lock" the light at one setting. It may be me, but I should have paid better attention to the reviews. I'm surprised at how short the battery life is.

I'm a true testament of the Garmin brand.!That's why it was a no brainer in making this purchase. The light seamlessly connects with the cycling computer. I'm able to check the battery's life from my head unit. And to my surprise, the battery lasts longer than expected. But like every other cycling light on the market. It depends on which feature you choose. I don't usually ride at nights so I can't say how bright it is. However, the light shines bright enough to be seen during the day. Which is what I personally prefer for my safety.

I bought the Garmin Varia UT800 Smart Headlight to replace my Garmin Varia HL500 Smart Headlight, which is now discontinued.

The HL500 was a very good headlight, but for one design flaw. The power button is made of a rubber-like material which degrades over time and eventually breaks off. This is the same design flaw that affected the Garmin Edge 100 bicycle computer.

The power button on the UT800 is much sturdier solid plastic. Just like the power button on the Edge 1030.

The UT800 emits a maximum of 800 lumens at the high setting. 400 lumens and 200 lumens modes are user selectable. Garmin says the 200 lumens mode provides 6 hours of lighting time. The UT800 also has two flashing modes.

The UT800 is certainly bright enough for the nighttime road riding that I do. I usually run the light on the low setting, only switching to high when there is no street lighting.

Which brings me to my favourite thing about the UT800. It can be turned on and off, and switched between modes from a Garmin Edge cycling computer. So no fumbling in the dark for the button on the UT800.

My minor gripe is with the locking ring mount used to attach the UT800 to the supplied out-front mount. If the locking ring is not aligned with the quarter-turn fitting on the out-front mount, the light will not be securely fixed to the out-front mount. There is no positive sign - like an audible or tactile click - to alert you that the UT800 is securely attached to the out-front mount. I found this out the hard way when my UT800 fell onto the road after I hit a couple of bumps.

To its credit, the UT800 survived its fall onto the tarmac with just a couple of scratches.

The UT800 is not the cheapest headlight, but it works as advertised. I think it is worth the price premium for the convenience of being able to control it from my Edge 1030.

Just make sure that locking ring is properly secured before you head out onto the road or trail.

One month of use, 11 rides and twice the mount dropped the light. the twist release is nice but poorly designed. vibration is allowing the light to fall to the ground. Not a recommended product for this reason.

With its sleek design and connectivity it's a hit with my Garmin 1040 and Varia rtl510 tail light. It's bright and the battery life is decent for daytime use, haven't used it at night - yet.

I've had another UT800 for several years which was a warranty replacement within the first couple months of that initial purchase due to greatly diminished battery life. The replacement was great and met or exceeded the stated battery life through several years of use. I recently purchased another UT800 and from day 1, battery life was well below stated and less than half of the old light in the same use cases. Garmin, admirably sent me a warranty replacement but unfortunately it has the same poor battery life. I don't know if it's a bad batch of batteries, a change in firmware or what, but I can't get past an hour of daytime riding without getting a low battery warning and another 30 minutes of power save flash mode before it dies. The old light is always good for 3-4 hours, even with more time at higher output settings, so a substantial difference. I probably wouldn't consider this light again, even though I like having an integrated system of Garmin head unit, radar and headlight. The battery life just doesn't cut it on the last 2 units I've received.

I just bought my second as the battery started to wear down after 10 years or so! Bright enough for riding at night, but I use it when road cycling as well for visibility in bright sunlight.

I use the headlight primarily during daytime road riding and use one of the flashing light settings. During these rides I keep the headlight disconnected from my Garmin 1040 since I don't need the additional controls (set and forget at start of ride). During rail trail rides where I will be going through tunnels I do have the headlight as part of the 1040's light network for the additional controls. Most of my rides are 2 to three hours long so I started to recharge the headlight after every ride since I haven't found a reliable way to determine remaining battery charge.

Easily integrates with my Edge 1030. When paired with my 1030 you can control the light mode via the 1030 interface. The light is easily installed on the bottom of my bike computer mount. I have experienced excellent battery life in the "Day Flash" mode - approximately 20 hours

I have been through several headlights despite the fact that I do not ride at night. I have used the daytime flash on all of the ones I have owned because the majority of my rides are on roads, not bike trails. Previous ones I owned have not had the battery life of the Varia UT800 which barely touchs the battery in a 3 hour ride. Those that came close were far more fragile or had a far from ideal mounting system. Assuming you own an Garmin Edge 800 series of 1030 (more recently 1040) this one uses a mounting system that attaches easily and securely to the underside of the OutFront Garmin mount leaving your handlebars unencombered by the device. I like this particularly because it is both secure and allows me to keep my hands on the bar tops rather than the hoods. Like all Garmin products, it is really sturdy. It can also be controlled with the Edge computer setting the style of lighting you want without having to touch the light at all while you are riding. I use it in combination with the Varia Radar light in back, so I feel pretty certain that I am being seen from both direction well in advance. Aesthetically, it looks solid and professional. It in no ways detracts from the beauty of your top of the line bike. As a night time unit, it throws a powerful beam which should be sufficient for any rider needing to see the road in front. I do recommend it if you have the upper level Edge computers.

This thing is great. Very powerful, multiple brightness options, daytime blinking 'be seen' option. Syncs with computer. Love it.

I use this as a stand-alone light (not synced with a computer) The light works very well and has a strong beam. I can see potholes and other road hazards easily at 20 mph. My one peeve with this light is that, after charging t, if it sits for more than a week, it seems to lose its charge. Then it will automatically go into an energy saving mode on the next use, even if you need full beam for a short timespan. I think that it's maybe using up battery searching for a Bluetooth connection. My work-around is just to charge the night before a ride. But my other lights can be charged and left to sit for weeks without losing their charge. Otherwise, this is a good light and the attachment options for this light work well for my needs.

It synced to my 1030 plus immediately. It adjusts brightness according to speed. It turns on during the day without me needing to think about it. The 1030 tells me when the battery gets low. It mounts well to the underside of my out front mount.

I haven't had enough time with it to really judge battery life but it seems okay. Remember that because it turns itself on when you start an activity that you have be ready to charge it even if you're only riding during the day. I've only been commuting with it and haven't had it out on a multi hour ride yet. I don't usually do more than an hour in darkness on either side of a ride anyway so as long as it lasts an hour I'm okay.

This light mounts as a Garmin well. I had a problem with a bontrager light that kept on falling off. The only big issue is that full bright light only works one hour rather than double with my bontrager. But I am very happy with it.
