Summary of Reviews

We have read all expert and user reviews on the Garmin Varia UT800. In summary, this is what cyclists think.

6 reasons to buy

  • The Varia UT800 can be mounted on handlebars or helmets, but only one of the two mounts is included in the price.
  • Mounting the Varia UT800 and syncing it with Garmin head units is easy, according to buyers.
  • The Varia UT800 is compatible with a standard GoPro mount.
  • Testers and owners praise the brightness at full power (800lm) and in daytime flash mode.
  • When paired with a Garmin bike computer, the light can be set to automatically adjust brightness based on time of day, speed, and ambient light.
  • This light has five modes ranging from high (800 lumens) to low (200) steady. It also has night and day flash modes.

5 reasons not to buy

  • Multiple owners report UT800 cases and mounting tabs failing. The problem appears widespread enough that Garmin runs an exchange program for it.
  • The Varia UT800 can’t be used while charging.
  • A tester and multiple owners experience connectivity issues.
  • Full-power battery life is poor. Testers and owners typically get around one hour, though one reviewer gets 2.5 hours with auto brightness control enabled.
  • Garmin advertises this light for trail riding, but the beam intensity and spread are insufficient to be a standalone light.

Bottom line

The Garmin Varia UT800 is a rechargeable bike light sold with a choice of handlebar or helmet mounts. It weighs 4.6oz (130g) and has a beam spread of 270 degrees. This light receives praise for its different modes and auto brightness control. However, it’s not bright enough to be a standalone light for trail riding at night. The Varia UT800's short battery life at full power disappoints, and it can’t be used while charging, so it’s useless for longer night rides. While most experts consider the Varia UT800 a good light, connectivity issues, broken mounting tabs, poor battery life, and the high price should deter buyers.

Garmin Varia UT800 – Overpriced Front Light? Or Top Tech With ANT+?

It’s a good light… but it’s an expensive good light… if you’ve got the money, buy it.

Garmin UT800 Headlight Real-World Review

… I recommend buying the UT800 kit with their handlebar mount. You have plenty of GoPro or third party alternatives if you want to stick this to your helmet.

Trail Tested | Garmin Varia UT800 Smart Headlight

On full power, the Varia UT800 is plenty bright and does a fantastic job of lighting up the trail. The mounting system is clean and secure, and the unit itself is water-resistant and seems to have a great run time.

Garmin UT800 Smart Headlight Review

The Garmin UT800 front light is compact, adjustable, low weight and is plenty bright for the majority of riders.  It  uses smart technology to maximize battery life without sacrificing the quality of the lighting.

Garmin Varia UT800 Bike Light | My Opinion [Polish]

After two months of testing this light, the only thing [to complain] about is… that this light simply cannot be charged while it is on.

Garmin Varia UT800 Review [German]

The highest level does use a bit too much battery for me, but otherwise, it is a really top-notch front light. The light intensity in particular is very good and does its job.
