3000 lumens of light output, four hours of maximum performance: The Megawatt Headlamp from Black Diamond is made for ski tourers, mountain bikers, and anyone who exercises outdoors in the dark. The device impressed in our test.
By the end of daylight saving time at the latest, you will be reading, hearing, and seeing the phrase "Now that the days are getting shorter again" with pleasant regularity. Now that the days are getting shorter again, you might want to buy this, rent that, or whatever else.
Now that the nights are getting longer again, I'm also coming around with a purchase recommendation. It concerns a product that turns night into day and should be of interest to all those who are active outdoors in the dark or in poor visibility. Be it on ski tours, mountain biking, or other outdoor activities.

Handling optimized for outdoor use
Two buttons on the Megawatt Headlamp from Black Diamond make operation very easy. Even with gloves on. One button serves as an on/off switch, while the other toggles between the two light modes. You can also use the same buttons to manually adjust the brightness of both modes. The low mode ranges from 100 to 800 lumens, while the high mode ranges from 1200 to a maximum of 3000 lumens. These settings can be changed at any time.
For comparison: The strongest front light I have tested on my MTB so far reaches a maximum of 2000 lumens. A bike light for city traffic usually manages with 150 to 300 lumens (approx. 15 – 50 lux), while front lights with 600 to 1000 lumens (approx. 60 – 100 lux) are recommended for unlit country roads.
The Megawatt Headlamp also has a red light mode. This is useful if, for example, you are entering a hut or moving between rough terrain at night. In both cases, the correct handling of the headlamp is crucial so as not to accidentally blind any tour partners. In winter, snow reflects light particularly strongly, thus increasing the glare of a bright beam of light directed straight into the face. The red light is also controlled via the buttons on the lamp.
The scope of delivery also includes a remote control that is paired with the lamp. You can then also operate the light remotely from the handlebars of your MTB, on your ski poles, or the backpack straps. Everything works perfectly. However, during testing, I deliberately did without this remote control because I don't want any more gadgets on my bike. I found the manual operation directly on the lamp to be downright pleasant. You don't take your hands off the handlebars for that too often anyway. Once the right light is set, you're done.
Furthermore, despite the solid rubber strap used to attach the remote control, it can happen that the part gets lost in the dark. Without you noticing. One more source of error that I can rule out this way. In short: Remote is nice to have, but not absolutely necessary.
The headlamp's further equipment includes two helmet mounts, a headband, a charging cable, and a storage bag.
50 watt-hour battery
The battery comes with a capacity of just over 50 watt-hours, which should be enough for maximum performance for four hours. This coincides with my experience – I am even of the opinion that Black Diamond is understating rather than overstating here. With the integrated LCD display, the current battery level can also be conveniently read at any time. When the lamp is switched on, the display also provides information about how the battery's runtime changes depending on the mode.
In my case, the approximately 85 percent battery in low mode with a little over 100 lumens lasts almost 26 hours, and in high mode with just under 3000 lumens, it's still a good four hours. This specific hour display is of course much more useful than a simple percentage.
You can of course also charge your mobile phone or other technical devices via the USB-C port. The battery also has an additional function where a small red flashing light can serve as a rear light if required.
In a nutshell
A well-thought-out product
With the Megawatt Headlamp, Black Diamond has developed a product that is very well thought out. I definitely like the built-in features. First and foremost, the LCD display showing the battery level in hours and minutes. Top notch. The two buttons for operation also impress me with their simplicity. Finally, NO app-based control. That wouldn't make sense out in the field with gloves and such anyway. The remote control is, as already mentioned, a 'nice to have' in my view. However, I consciously choose not to use it. With the second mount included in the delivery, I can use both a mountain bike and a ski helmet. Or, nomen est omen, use the headlamp with the strap as an actual headlamp. Furthermore, the build quality seems very robust. What else can I say? Now that the days are getting shorter again and you need a light for your outdoor activities in the dark, the Megawatt Headlamp is certainly worth considering.
