    Is there an upgrade to the Nitecore MH20GT?

    A "purely flood beam profile" does not seem great for distance. I do not need a real far thrower but use it for navigating in the woods and the mountains. I also find the MH20GT was good for lighting the road on my bike to avoid pot holes and other obstacles going down hills with a good spot a...

    Is there an upgrade to the Nitecore MH20GT?

    My Nitecore Mh20GT just died this week. It was a great light for running, hiking, and biking (with a Fenix bicycle mount). However, I am done with Nitecore as this is the third product to die recently. (A charger was dead on arrival and an HC60 stopped charging while still under warranty...

    Nitecore F1 Charger / Battery Pack Review

    I bought an F1 to recharge my phone/gps while hiking in the backcountry. It arrived with a defective micro USB connection -it did not work. It seems that the product has been discontinued. This is the second Nitecore product to have this defect. (An HC60 headlamp micro USB charging port...

    light measurement app

    You can measure light levels as a function of time then export the data as a text file. The light meter seems sufficient for determining burn time (time to half the maximum power). The app I reference seems good for measuring periods of seconds to minutes. I would like to measure burn times...

    Fenix LD25, LD40 (link to pic thread)

    Thanks for the great review. This might be my solution for >100 lumens that go all night. Do you know if the LD40 has a lock out mechanism to prevent accidental turn on in my bag? For instance on many Fenix lights, unscrewing the tailcap a quarter turn will disable the light. Perhaps it...

    Fenix LD40 Review

    Fenix HP10 - beamshots and a few thoughts

    The HP10 is a great thrower, but a diffuser would be necessary for things like setting up a tent or even reading a book. I will get one despite the flaws. On another note, I took my HP10 for run last night on single track. The light is awesome. However, the band and suspension system are not...

    Princeton Tec Amp 4 discharge curve

    The Princeton Tec Amp 4 is an old light. However, it is low cost, uses easy to get AA batteries, and has a good power level for me. Before I get one, I would like to know how long the light will work at or near the regulated output level. The company does not respond to my request for...
