The MH10 is Ledlenser’s newest, top-of-the-line headlamp. It offers three different brightness settings: 600 lumens with a 10-hour run-time, 250 lumens with a 15-hour run-time, and 10 lumens with 120-hour run-time.
The lamp runs at full power for the duration of the battery’s life – dimming just a few minutes before it is completely drained.
At 600 lumens, you have enough light for night biking and caving, while 250 lumens is good enough for tramping in the dark, and 10 lumens is enough to read a book.
The headlamp is powered by a 3400mAh lithium ion rechargeable battery.
I used the MH10 on a recent week-long caving expedition as a secondary light underground and as a primary light around the campsite on the surface. Like other Ledlenser headlamps, it has an adjustable beam which can be set to broad or narrow, giving a throw of some 150m on high power. On its wide setting, the light did not give enough spread to easily cave by, however it was excellent for searching out trail markers on late-night excursions. Knowing it has a long battery life was also reassuring.
The MH10 comes with a small pouch and extensive instruction manual. At 158g it’s the heaviest lamp in this review, but that weight is reassuring because it feels well-made. It is also one of the brightest headlamps on the market.
If you like a powerful beam, this is the headlamp for you. But at nearly three times the price of the other lights reviewed, it’s a bigger investment. However, it promises to be capable of handling the rough and tumble of outdoor activities, so over time that investment may pay for itself.
