Gloworm is a New Zealand-born company formed in 2010 with the sole aim of developing powerful LED lighting systems for cyclists. Over the last decade, they have excelled in developing and improving affordable lights for road cycling and mountain biking, consistently beating out competitors in terms of lumen output, battery life, and smart tech. Suffice it to say, Gloworm lights make you look forward to the end of daylight savings when you can charge them up and embark on the first night ride of the season.
The ever-popular Gloworm XS has been paired with the Power Pack 5 to create the XS Adventure. This pairing allows a lighter-weight setup without sacrificing light output. The XS is the perfect balance of weight and output making it light enough for the helmet and bright enough for the bars. Combine its 2800 lumens with the convenience of a wireless remote and Mobile App customization and you've got the perfect partner for your next after-hours escape.
Gloworm Link Mobile App — Gloworm Link makes customization of your light simple and convenient. Link allows you to select between 1 and 4 light levels and the type of light pattern for each level- Fixed or flashing. You can program the intensity of the fixed beam from 1-100% or choose from one of three flashing patterns. Link will also provide current battery charge and diagnostic information.
Default Settings: Low (20%) / Medium (70%) / High (100%).
The Special mode emits a disrupted flash pattern. Special mode is activated by double-clicking the button when the light is off. This allows the user to conduct any outdoor activity without having to cycle through the special mode and having an interruption of a steady light beam. The light is turned off by holding the button for approx 2 seconds.
***The main difference between the 'adventure' light and the non-adventure is the non-adventure has a larger battery pack — the non-adventure has power pack 10, and the adventure has power pack 5.

Mixed review for this product. Some background: I installed this on my wife's bike. We typically ride early in the morning, starting at 5:30AM to 6AM, for 1 to 1.5 hours, 5 days per week. All city street riding. Wanted a light to illuminate the road close and far, plus some side spread. Also wanted a flashing mode for daytime rides.
First, the positives. The light intensity and light pattern are outstanding! I stuck with the original lens pattern; no improvement needed. At first I thought that the app's ability to customize settings was just a gimmick, but it turns out that I love this feature. Lastly, my wife loves the remote switch. She has some limited motion with her thumb, and the remote switch makes it very easy for her.
Now, the negatives. The battery life is way under the manufacturer's claim. I've used it for multiple charging cycles, as per their advice in their FAQs, and it hasn't improved. I find that after 4 hours on 10% power, I only have 35% remaining. Can't imagine what the run time is on full power. Also, the overnight temperatures in my garage are typically 32 to 45F and daytime is 40 to 60F. If you live in a colder climate, your run time is sure to be considerably shortened.
Next, the light loses 4-5% power overnight if you leave it connected to the battery. Finally, the light loses synchronization with the button overnight, even when I do leave it connected. This means that I have to go thru a resync procedure every ride. This involves unplugging and re-inserting the USB connection. It's unlikely to wear well. I expect that either the light side or the battery side connection will break within the year.
Gloworm is oh so close to a wonderful product. They just need to improve their battery management, which probably can be accomplished with a firmware update. (Turn off the wireless communication if the light is idle for 10 minutes. Restart it with a button press. Or some other solution, such as a disconnect switch in the USB cable.) I would not recommend buying this product until Gloworm recognizes and fixes this issue. If they do address it, or if you are OK with the limitations, then this is a top notch product.
