At A Glance

We’ve been fans of the Diablo range of lights for some time, last year the Diablo Mk4 was a clear favourite amongst the test team and this year the Mk5 instantly got whisked away from the office as soon as night fell. The build of the light is the same as last year, but this year there are 1100 lumens of output for the same run time on the battery. At just 106 grams it makes for a perfect helmet light and Exposure ship the Diablo with a great helmet mount. It cleverly sandwiches itself into your lid without using Velcro and is solid no matter what the terrain, it’s also easy to remove and won’t leave a mark.

On The Trail

Despite its diminutive size and weight, don’t be fooled by the Diablo, its very bright and if you ride reasonably short rides then it would make the perfect companion as your only light. It features the Optimised Mode Selector button that allows you to fine tune the power output to increase run times. On high power it only lasts for an hour, but if you put it in a lower setting on climbs and when transitioning between more technical sections of trail you can easily get over 3 hours worth of usage. Even on the medium mode it is plenty bright enough to ride with on its own and it casts a solid beam of light right out into the distance as well as giving good spread to the sides.


Small, lightweight and with a very well engineered mount the Diablo should be on your radar when you are looking for a simple helmet mounted light. It’s exceedingly powerful for it’s diminutive size, just be sure not to leave it on high power mode on a long ride as you’ll quickly use up all of its available energy.

His first mountain bike was a Trek 820, which he bought in 1990. It didn’t take him long to earn himself a trip to the hospital on it, and he’s never looked back since. These days he’s keeping it rubber side down, riding locally and overseas as much as possible.
