Olight Perun 3 Headlamp Review

[@antihuman09]

Great review. Answered a lot of the questions I had, like whether the included battery could be charged normally and whether the light would run on a standard 21700. One of the reasons I picked this light up is that, like the Nitecore HC35, it can be placed offset in the headlamp holder. I hike at night with a baseball cap and most lights won't throw just in front of your feet with a hat on as the bill blocks the beam. Being able to clip just the tail of the light (utilizing only one of the two clips) so the beam is far enough to one side or the other that it isn't blocked is a function I didn't know I needed in my life until I had it. I always hike at night. Thanks again for the awesome review.

[@SamFrancis-v6h]

Nice job! Lots of useful information.

[@donaldstrader7241]

I appreciate your covering the battery compatibility a bit after 2 minutes into the video. I don't have a lot of spare 21700 batteries laying around, other than in other Olights, but always good to know this information. I also especially appreciate the color temperature information of the white and red beams starting at around 10:30 minutes into the video. And of course the rest of the review!

[@slaughtercrx]

I wish Olight would have emitter option for high CRI. At least you have battery options other than thiers…..

[@cheule]

Agreed. A high CRI model along side the CW low cri one.

[@stephenathon]

Yep. No high-CRI, no deal.

[@mackiemack3689]

Most important no go for me with olight is 150 -600 lumen - nothing between - plain stupid 600 lumen is too much for arm reach work, 150 is not enough

[@HisGraceHisGlory]

Awesome, going to watch your review now! Thanks for posting this so quickly!!

[@cheule]

No problem!

[@chrissewell1608]

I love my O-Lights! 😊 Its good stuff, and makes great gifts, when caught on sale!

[@jaskiniamestwa]

excellent review, I was looking at perun for a long time, but somehow held off, since I already have few olights...this might be the one I finally get.

[@cheule]

Thanks for watching!

[@chrissewell1608]

I use my original Perun, every week for something!

[@PURAMAMii]

Thank you for explaining things so nice and very well detailed and even showed us how to use the flashlight see other tutorials and they just pop up instructions instead of showing you

[@sloanNYC]

Glad to see them supporting non-proprietary batteries more and more and some models using USB-C charging. For the sale price, this is some great output. I loved my Fenix HM61R, but it has much less output than this and the HM71R is more $$ and trades the Red for a flood and throw combo. Wish there was a combo of this one and the Fenix 71R! The Fenix 71R has 800 lumens high spotlight which is nice though.

[@cheule]

Thanks for the comment.

[@ernesto18guanaco]

Very well put together love all the instruments and effects used in this video. Absolutely thorough. Enjoyed when you mentioned about the battery because their website is sold out. New subscriber here and my first video from you.

[@ernesto18guanaco]

Would love to know what are your top headlamps after this one. This is already going to replace my Milwaukee hardhat lamp

[@cheule]

I use the Perun 2 mini headlamp all the time. Much less runtime, but feather light. My particular Perun 2 mini has been emitter swapped to Nichia sw45k, which makes it even better for my tastes.

[@ernesto18guanaco]

@@cheule awesome. I’ve been looking for mainly battery life. But I think I found something I’m excited about.thanks for popping on my feed keep up the great videos.

[@dialucrii31]

​@@ernesto18guanaco FWIW I have the perun 2 and it is a little too heavy for prolonged use (12g heavier than the perun 3). I'd actually rather have a spare battery and a slightly lighter light, but still with these specs. Sure I'd have to swap the battery out for the same run time, but it would make the light more comfortable to wear for that long time, so it's a worthwhile compromise, in the case of a head torch, IMO.

[@ernesto18guanaco]

@@dialucrii31 so most my headlamp use is in the construction trade and right now the perun 3 is amazing in battery life. Far exceeds the Milwaukee 600. But for around the house I prefer a smaller one so will try a perun mini. Thank you

[@justinconley7978]

Does Olight make a headlight with a green light. I want a headlamp for hunting. How bright is the red in the dark? Thank you.

[@mattyosborne1453]

I wss realy hoping it would have a spot light mode along with a wider spead mode

[@Weech.]

Chuele I like your waves brother!

[@gregcushing1716]

The Strap needs to be improved, the metal scratches the light. Hopefully that will be improved, and given free to those that bought now.

[@copperspartan1643]

Would this be good for farm work, e.g. emergency fence fixes, herding escaped cattle at night? It would mostly be for up close / medium distance. I’ll carry something in my hand for spotlighting. Doesn’t need to be super light weight. Ruggedness, long running and reasonably weather proof would be top priorities.

[@TobyCostaRica]

Yes I would use mine for what you described. 21700 is as big as you’d want for a front battery headlamp. 600 lumens for 300 mins is pretty bright for a long time Anything larger you’d need a waist battery pack. I’d get a Javelot 2 Pro for spotting. Thing has range

[@copperspartan1643]

@ thanks.

[@mackiemack3689]

@@TobyCostaRica 600 is too much - 350-400 will easily do giving u way more operating time.

[@TobyCostaRica]

@@mackiemack3689 the light discussed in the video has a 600 lumen high or a 120 lumen medium. If it was an Anduril light you can just dim it to whatever you want

[@sztaylor89]

Ever try an amber instead of red for scotopic vision preservation? Been thinking of getting a white and amber surefire aviator

[@cheule]

Not a scientist, but my understanding is for the rods in your eyes to be unaffected by rhodopsin depletion, the wavelength has to be around 650 nm or longer.

[@Trickster_24]

@@cheule google says 620-700

[@squarebody4546]

Does it indicate battery life with a colored LED in the button?

[@thejudge3094]

could you make a comparison with Sofirn HS41

[@cheule]

I don’t have one, alas. History tells me that this would be slightly more refined. Based on other sofirn and Olight products I’ve directly compared. Sofirn is s budget brand and punches way above its price point, but Olight products do give more refinement for the extra money.

[@HisGraceHisGlory]

Would this be your headlamp of choice for backpacking and through hiking?

[@cheule]

Definitely. The CW nearly 7000k CCT is actually better outside than a high CRI 3500k-4500k for seeing the trail. I know that sound dubious, but I was having a chat with David Livingston of Cool Fall, and he said that in his rural area, 5000 to 6500k low CRI performs much better in the wood. I did my own tests, and I confirm it. I can see bushes and trees better than with the warmer CCTs. I think it has to do with the was warm brown tones and lush green tones both come alive at 3500k high CRI, while cool white low CRI provides a much better contrast between ground and bush, sky and tree at night. Do the tests yourself! It’s amazing really.

[@HisGraceHisGlory]

@@cheule Really great reply and info. after watching your review I think I am going to hold off on the Perun 3 and search out a different solution. Thanks Cheule, no one does it better on KZbin for flashlights than you do!

[@donaldstrader7241]

@@cheule Glad to hear that, and combined with some of the other features, red light, run times, headband that allows the clip to remain, and upgraded switch with battery level indicator, I went ahead and ordered one. That said, for my eyes, I don't really agree that CW is better, although when you get down to 5000K, then we would agree, as that is becoming neutral. The cooler the light the less well I can see, as things become much more two dimensional. Better color perception adds more depth perception or three dimensional appearance. I did read a hiking book, and he liked to keep his light lower to reveal more shadows/ three dimensions to the trail ahead. That makes sense if one can do it. It is probably why there are a couple companies that I saw advertising light belts in warmer tints, to do that very thing, to illuminate the texture of the trail to see and avoid holes and other trail issues at night. Another reason for warmer tones is that besides projects needing better light and color perception, people tend to use headlamps at night. LOL. Warmer tints are less destructive of circadian rhythms for better sleep.

[@cj70399]

Can you still rotate light with metal headband clip?

[@cheule]

Yes! And the right angle clip nestles into the headband clip.

[@jt44444]

Yes and there is a disclaimer that doing this will scratch it if that matters to you. Functionality matters more than looks for me. So scratch away! ;)

[@mackiemack3689]

No its locked upwards in one position for life

[@phillymetalhead]

This does not feel like an upgrade over the 2. My Perun 2 with a 5k cell has these exact same outputs and runtimes. Seriously disapointed as the Perun 2 is nearly 4 years old.

[@tyg5265]

Anyone have any experience using one with a bike helmet? Wondering if it would work or just too big.

[@mercruial]

Good review thanks

[@AllAboutAdventures]

I don't really see a point in having the red light. It doesn't seem to preserve my night vision. I'll use the moonlight mode before the red any time.

[@cheule]

I 💯 agree. I think it’s one of those whiteboard ideas that doesn’t work as well in practice.

[@Studat]

I love red light, especially in summer when in the bush, doesn't attach bugs and great for your night vision

[@sgtkey9416]

With red light you are also more hidden. A human eye can’t see it as good as white light. Most used in the military.

[@Studat]

@@sgtkey9416 I thought it was used in the military 🪖 to preserve night vision

[@twoq5028]

I’m a Ground Search and Rescue team lead. The red light is awesome when you don’t want to blind the team do a debrief etc. I have a Thrunite and a Nitecore headlamp. Really miss the red light on my Thrunite.

[@grahamwinter5536]

👍 Great review. Just one question do you have to remove the clio to fix it to the headband?.

[@utubetjc]

No, it does not need to be removed.

[@cheule]

Nope! It inserts right into the headband clip. The right angle clip is on the light in the image for the video if you look closely. Near the head.

[@grahamwinter5536]

@@cheule👍 excellent, it's a pain to have to remove the clip on the Perun 2, and can get lost if you aren't careful storing it away 😉

[@aussiehardwood6196]

I gave away my Purun-2 its was just too heavy and sloppy as a serious headlight. The basic physics were dead wrong.

[@cheule]

My main headlamp is the Perun 2 mini, because it’s so lightweight. But yeah, you just can’t get around physics. If you put a 21700 in a headlamp, you’re looking at around 150g on your head.

[@aussiehardwood6196]

@@cheule yeah, I liked the output and simple UI, the emitter and optic was great, the sensor and nice taper in light when U hit the off button. All great, quality great. It's just strapping a 21700 cell to your forehead, that didn't work. I now use a single 18650 headlamp from Sofirn with 2 sst-40's. It's not Olight quality but works a bit better. I think seperating the power source from the emitter might be a good option for headlamps. Olight gave me a 'Array' headlamp that I gifted my nephew, that had the battery at the back of the headlamp strap which worked pretty good but it was only 400lm. Which really is probably ok for 90% of tasks U use a headlamp for. An 18350 headlamp may be my next. Easy to carry some spare cells if needed.

[@donaldstrader7241]

@@cheule I love the Perun 2 mini and about the only nit pick I can think of off the top of my head was the lack of a red low. Although I love the brightness of the available red, it needs a low to as part of its cycle. After all they manage to fit a SOS level/feature and a turbo red. And then since its lightness is allowed by a relatively small battery, it combines well with the Baton 4 Premium, so you have additional power available.
