Black Diamond Revolt 350 Head Lamp | Review

A straightforward and practical new head torch from Black Diamond. Here's our verdict on the Revolt 350

Why We Chose The Black Diamond Revolt 350: Powerful, bright, fully-featured and comfortable to wear

Compared to some of the more exotic head lamps in this year’s Outdoor 100 – like the BioLite HeadLamp 750, or the Petzl Iko Core, for example – the Revolt 350 from Black Diamond looks a lot more familiar. In many ways, it’s a conventional head torch, with the LED light and battery pack placed at the front in one compact unit, with a wraparound headband.

That’s no bad thing. It’s a tried and tested design that has proved its utility over many years. But this head lamp is still far from basic. Like Petzl’s CORE battery pack system, Black Diamond have their own range of rechargeable batteries, and the Revolt 350 includes a BD 1800 Lithium-Ion cell, which can be removed from the lamp’s battery compartment and charged via USB. Again, just like Petzl’s rival CORE system, this makes it easy to swap out a dead battery pack for a fresh one, or alternatively to power the lamp using 3 x standard AAA alkaline batteries.

Who Is The Black Diamond Revolt 350 For?

With both proximity and distance modes, plus dimming, strobe, red night-vision and lock functions, this is a practical head lamp for climbers, wild campers, backpackers, hikers and hillwalkers.

The ability to use either the included USB-rechargeable battery pack or 3 x AAAs also makes this a good choice for extended off-grid adventures – whether your preference is to carry spare batteries or a fully juiced power bank. The lamp works with either option (and if you also purchased a second BD1800 battery pack, you’d get maximum versatility).

Materials and Construction

The body of the lamp is made from chunky plastic, as is the bracket that attaches it to the elastic headband. It has a softer rubberised front surround to ward off bumps, with two easy-to-use buttons on top of the unit, plus a little three-LED battery indicator on the side of the head lamp. The headband itself also has perforations to reduce sweat build-up.

Producing up to 350 lumens of light, this is a fairly high-powered head torch, though admittedly not as bright as some of the other options in this year’s Outdoor 100 selection. Still, redesigned optics make the most of the power on offer. It’s more than adequate for most users, and has the advantage of being intuitive to operate thanks to a second switch that switches between the different LED lenses. You can have either spot or flood modes, depending on whether you’re trying to pick out landscape features down the trail or cast a wide circle of light on your campsite. There’s also a red light mode for preserving night vision.

Helpfully, the lamp has a brightness memory, so it will remember your preferred light intensity next time you turn it on, and you can also instantly ramp up the brightness with a single tap, rather than having to cycle or press and hold the main button.


There’s a lot to be said for keeping it simple, and the Revolt 350 certainly delivers in that regard. It’s well-built and easy to use, and will be a solid, reliable head lamp for hiking, climbing and camping. It’s reasonably light and comfortable to wear, tipping the scales at around 90g, though the traditional design puts all of that weight at the front of the head. There’s no overhead strap, which keeps things simple and makes it easier to use with a helmet, but can lead to a little bouncing if you’re moving fast. Then again, this isn’t a specialist trail running head lamp.

“This is a practical head lamp for climbers, wild campers, backpackers, hikers and hillwalkers.”

There are also enough features to add plenty of versatility without overcomplicating things for the user, while the ability to use either the included rechargeable battery pack or standard AAAs also adds flexibility in the field.

Tester’s Verdict

Ash Routen, outdoor expedition writer and photographer

The Revolt range from Black Diamond was one of the first to include a USB rechargeable battery, and the big thing that stands out in this latest Revolt 350 is the ability to run the headlamp off the included lithium battery or standard AAA batteries. This is a big plus for me. On multi-day trips, particularly to remote regions, you just can’t rely on re-charging electronics on solar or powerpacks.

“The Revolt 350 could be described as a solid all-round headlamp. The strap is excellent, with strong elasticity and a hard-wearing weave. I find many lightweight hiking focused headlamps tend to have rather puny straps. The lighting buttons (particularly the mode selector) are a little on the small side, especially if you’re wearing gloves. But there is a nice “powertap” function which allows you to switch between the main and dimmer bulb simply by tapping the side of the lamp. 

“I also like the fact that you get a battery life readout on the side of the lamp. There’s nothing worse than having to fiddle with replacement batteries in the dark. Especially as accessing the battery compartment is a slightly fiddly affair.

“The 350 lumens produced by the main bulb has more than enough reach for hiking purposes. I have a 400-lumen lamp for Arctic trips that runs solely off of AA batteries, and throws a beam of light at least 50 meters (although claims at 115m on its brightest setting). I’d be surprised if the Revolt manages to hit the claimed 80m mark.

“One final feature that I think is worth highlighting is the angle adjuster, which feels reasonably sturdy, adjusts smoothly and clicks into place very positively.”
