G'day Adam,

The battery is charged via USB, and takes approximately 3 hours to fully charge. As far as we know you can't overcharge the battery.

Hey, thanks for your question!

I myself actually have this headlamp and you're onto a winner here! We've actually got three of the same torch in the family... 

As far as the 1minute decrease, having used this myself this is something I haven't noticed. As specified on the LED Lenser site the management features are: 

Full control over your power status
Low Battery Warning - it warns you when the battery is low
Charge Indicator - it shows the current charge status of the battery

I've never noticed it drop on its own other than at low battery and can't find any mention of it on their website either. The review left on our page could have been due to low battery.

All in all, your husband, I assume, will be stoked!

G'day Micahel,

The MH10 battery is a 18650 Li-Ion battery so you could grab yourself one of those and keep it charged up and switch over when needed. We sell one that Nitecore make here in our store, we could add to an order if you give us a buzz as soon as you place your order. Give us a call if you need clarification.

G'day Shane,

Yep, you're spot on! The Ledlenser MH10 LED Headlamp comes with a set of red and green colour filters which you switch over with ease. Check out the video on the product page to find out how. 

G'day Alex,

Yes the MH10 LED Headlamp has a focus adjuster to make the beam wider or narrower.

G'day Angus,

I've just given our rep a buzz and she confirmed that there isn't a strobe or blinking function on the Ledlesner MH10 LED Headlamp.
