ThruNite TH20 520 Lumen CREE XP-L LED Headlamp Flashlight -Lightweight Waterproof IPX-8 EDC Headlamp for Indoor & Outdoor Hiking,Camping, Cycling - CW

La opción del frontal ThruNite TH20 de poder seleccionar el número de lúmenes desde cero al máximo escalonadamente es una gran característica.El modo " luna" y "SOS", en situaciones de emergencia pueden llegar a ser muy útiles.A esto hay que añadir que puede utilizar pilas AA alcalinas, recargables ni-mh AA, primarias de litio AA, y pilas recargables Li-ion 14500.Es un frontal con un haz de luz muy amplio, me refiero a que no es un frontal cuya luz llegué muy lejos, aún así en mi opinión es un buen frontal.

乾電池がとけてた?　ベトベトナカミ壊れてました。その他問題なし｡

It’s decently bright and the dimming/brightness feature is nice. good around the house of a backup light on a hike. However, I think the band is low quality (head band). I like it!

This headlamp is a relatively lightweight device with good illumination properties for such a small lamp. The build quality is very good as well, as the housing is all metal. The manufacturer also supplies two extra o-rings to replace the one keeping the battery compartment watertight, if you should need a ring eventually.It has several settings, from 'Firefly' (0,3 lumens) to 'Turbo' (250 lumens on an AA-battery, 520 lumens on a 14500 mAh battery) which can be set via the switch on the side. All modes are mentioned in the manual, although a little practice is required to get used to them.It is useful for hiking, cycling and camping, but also for activities around the house that require the use of two free hands (i.e. messing around inside a PC or the engine compartment of your car). It's less useful for jogging and running as the headband doesn't have a top strap to prevent it from sliding down your face (you do have to pull the horizontal strap quite tight then, which can be uncomfortable), but for my personal use while cycling and hiking that's not a big deal.It runs on a single AA-size battery. I haven't tested how long that keeps it powered effectlively but according to the manual it should be around 90 minutes at the 230 and 250 lumens settings. It lacks a rechargeable internal battery and USB-C port, which some consider a disadvantage. However, for my use case that's not a problem.All in all this is an affordable headlamp of good quality, with sufficient illumination properties.

works well, easy to load in the dark...enough light to walk dark trail
