    Best lightweight headlamp for trail running (2017)

    So i bought the NU20 CRI by Nitecore. It works fairly well and is ligtweigt. It had a good price of around 26$ after using a coupon. Also works great as a dog light-collar! Much brighter than any other collar. The tint of the light is visibly colder than the 3D tint of my BLF A6 but also warmer...

    Best lightweight headlamp for trail running (2017)

    So i've read the specifications about the H53 zebra light, it seems to use a NiMH and output 280Lm for almost one hour? That's good for an AA light. The lumen settings also seem usefull. I wonder how it compares to the NU20 as that seems to have 270lm for 30 minutes (which is worse) but 170lm...

    Best lightweight headlamp for trail running (2017)

    Hi! I'm looking for a headlamp for trail running with priorities as follows: 1) Weight (strap + battery included, must not forget that an extra headstrap weights more, i would not mind that) 1b) Comfort 2) Brightness somewhere in range of 120-200lm, around two hours of runtime 2a) high CRI or...

    BLF-348 LED replacement

    Allright here are some notes. XP-L is cheaper than XP-G3, at least for a single one, one can get 10xp-g3 for 15$ XP-G2 is what Lumintop Tool uses (wouldnt be a very good upgrade i think, unless i used a different tint) Im just worried about hte voltage, if it says "Voltage:2.9-3.5V" it probably...

    BLF-348 LED replacement

    That's exactly what i did, used a candle and a piece of aluminium foil and it was super easy and fun. I had a good feeling that i could succesfully replace the LED this time, then i realized i have no idea how to find a compactible LED. "footprint" is that how its called? Ill give searching it...

    BLF-348 LED replacement

    Cool i might try the worm then if the LEDS are more expensive than the flashlights EDIT: I would like to check a local electronic components store for LEDS i could use (better cheap than nothing) however i cant find the right TYPE of LED... What are the typical flashlight LEDS called? My guess...

    Lumintop Tool + Nichia BLF-348 Experiment

    I just realized, since the LED broke but the rest is in tact... i could just replace the LED. What LED should i get to get the most lumens and neutral tint? And where? I will make this light a pocket flashlight for my mother who cant see well in dim light, so it needs to be bright enough and the...

    Lumintop Tool + Nichia BLF-348 Experiment

    10mm sinkpad looks good, but i haven't found it together with a LED, so i should attach the LED myself? I already ruined one just soldering the wires next to it, i don't even want to imagine what will happen when i try to solder the LED directly.

    Lumintop Tool + Nichia BLF-348 Experiment

    I've been enjoying the tint of the blf-348 very much however, i felt like the brightness is exactly in the least useful zone for me. It's too bright closer than 1,5m and too dim when further - especially outside, makes a good walk-with light when its really dark though. Suddenly, one morning...
