Electron only claim it has a 165 lumen output, but its reach is good and there are no distracting holes or halo disturbances in the beam. There’s barely any light thrown to the side though, so it only really works on technical trails as a helmet light. The problem is that it doesn't have a mount though, so you have to fudge one out of a velcro strap or zipties.
The small mode-change/power switch next to the charger port on the back can be hard to ﬁnd, especially when you're wearing thick winter gloves, but the audible click it gives means you know when it’s switched outputs. Battery life is good enough to let it run full chat through most two- to three-hour night raids without it going ﬂat.
Despite the affordable pricing we’ve had good reliability in three years of running Electron lamps, and this year’s crop has been trouble free too. The Terra Mini is great for commuting or even as a general-use torch, and the inclusion of a USB charger is a bonus.
