Fenix HM70R vs Nitecore HC68 - Triple LED Headlamp Heads Up 

Thoughts between this and the hm65r?

@zaanea1 I never understood if this HM70R drops in brightness after a few minutes. The official graph of the manufacturer does not show details, it can only be seen that after about 20 or 30 minutes it drops from Turbo level to an intermediate point between High and Turbo. (but it is not clear if they are 600, 700 or 800 lumens) Also on the flood level we see a drop in the graph but it is not clear whether it drops to 200 or 300 lumens. Can you tell anything about this from your use of the headlamp? Thank you

People who buy the 70 specifically wanted the 5000 mAh battery.

​@@rsilvers129I think the OPcs point was that the reviewer said, or insinuated, that the weight is not very different, and it's actually very different.

That's because their other RU-vid channel is called Nitecore store lol

@@M.L.Knotts is it actually? Lol cuz I came here for references on what I should buy

@@JaRa911 yep sure is go to that other channel you'll see the same dude doing reviews in the same place

@@M.L.Knotts confirmed

@@JaRa911 I'm not insinuating that there flashlights are bad or anything, they are decent, but they're advertisement practices are not

😭 why I did not see this...

both Nitecore and Fenix are pretty honest about their runtime. one who greately exagerate is LedLenser, but not on all their products.

@@randomescu and yet my 12 year old LED Lenser is still probably my favorite light. In the end, it’s beam quality that matters.

@@rsilvers129 indeed, some LedLenser are very good. I gave to my brother and to my uncle the MT10, for bycicle and fishing. But some LedLenser are very power hungry, with a low runtime, lower then stated by them, especially at higher levels.

No, he is paid do not say that, see other videos from him

Fenix are pretty accurate in my experience. HM70R specs give accurate run-times from what others are reporting. The claims for the HM65 though are way over the top.

@@paradoxicalcat7173 someone said there are true but with a great loss of lumens. while the 65r-t is more regularised and last only half of 65r.

@@randomescu Depends where you start. If you run high/turbo then the drop off is more dramatic and deeper than if you start at a lower light output. I work on the basis of using 50% of the max output most of the time, and at this point, the lights seem to deliver. I check the runtime and step-down for the mid/high settings and see what it does. HM70R seems better than HP25R V2 in that it gives 500 lm, not 400 lm, and no step-down. 65R-T gives half the run-time posted on the box vs. 65R, because they are exaggerated. I'm not sure why these lights are so far out. You can check the run-times mathematically. Assume 200 mAh per lumen and you can easily check how close the box figures are (200 mAh will result in conserative estimates but still close to real-world). The lights I have are all around 156 mAh/lm. Battery capacity / box run time / lumens = mAh per lm the figure is based on. It should be 150-200 if it is accurate.

Just buy a higher mah battery , or if you vape, stick a flattop inside with a magnet on the end of the battery

there is no way one could get 22 hours on 400 lumens from 18650...just physically impossible.

@@ApocGuy yep it's 3500 amh and well on the spot light on 400 lumens but goi g down to next setting it was finally in for 18 hours then 6 hours on spot lowest mode

Hint- It's not Nitecore

God gave you two eyebrows and eyelashes for that :D No need to worry

@@oO2Pro4UOo I don't know how high tech your eyebrows are, but for most people, when working up a real sweat for an extended period of time, the "builtin" sweat protectors just won't do. There's simply too much water to absorb.

Thanks for the heads-up! I've been very impressed with Fenix so far. Think I'll get the HM70.

Maybe your unlucky with nitecore ive owned a few nitecore lights and they have never let me down over the past 7yrs out in the fields & at work... sometimes we do get a batch of faulty item's in anything we buy some people are lucky never to obtain them and some do...

Over 100 lights? I thought I was obsessive with 15!

@@jamescline9973 yeah, I have a problem, 21 headlights alone. The skilhunt is my favorite with the TIR lens and 5K tint emitter. It's perfect for mechanic and close up work

I have the Acebeam H 40 high cri. I like the high cri, but I have come to really appreciate the convenience of usb c recharging. I just ordered the Fenix HM70R. The floodlight is said to be cri 90. I am sorry to disagree with you, but my 2 favorite headlamps are the Nitecore NU35 and the Nitecore HC68. The Fenix is similar to the HC68, but has high cri and a longer runtime. I have never had a problem with my Nitecores, and use them more than all the rest of my headlamps put together. If they fail anytime soon I will change my opinion.

I believe nitecore sells a special cold weather battery that has higher output in extreme cold situations down to -40 compared to the degrading performance of any typical 18650 as the temperature drops. Fenix also made special cold weather batteries for the same purpose but it appears they discontinued them.
