Olight X9R Marauder  25000 lumens

will34 · 2018-06-08T20:23:10.000Z

A light of this caliber without active cooling is laughable, even a small fan with high airflow rate could do a better cooling than adding more massive fins and decreasing the turbo runtime. I would like to see acebeam x70 runtime charts for comparison.

As for the H2R not being dangerous, I put mine to test last year and found out the battery is not protected when you short both front poles, and after several attempts it triggered the 30Q’s internal protection (not PCB protection). It did not get hot or vent, but certainly it puts the user in a possibly dangerous situation.

SKV89:

Are you referring to the H2R or the X9R? For the H2R, I sent them an email and they sent me a revised cap. However, I did alot of research on it and some testing was done on the original cap (I think it was on a Russian flashlight forum, can’t remember) and it wasn’t as dangerous as we thought.

I also got a replacement tailcap for mine with no hassle, and the other magnetic tailcap charging Olights I have seem to be OK as received. I did manage to get a couple of 0000# steel wool pads ablazing with my original H2R tailcap, but it seemed like as long as I kept it out of the shop it would have been safe (as I can’t remember the last time I encountered a Super Fine steel wool pad in the woods or one of my flashlight carrying bags/cases.) It’s comforting to know it can go anywhere now though, as it’s sometimes hard for me to to remember which of my lights have specific usage restrictions. Life seems to be getting less stressful in that regard though as most of the lights I’ve bough recently were IPX-7 or better, which removes one of the biggest restrictions.

The heatsink in that light is massive, i think they said after those 3 min on highest the head is not really that warm so i think they did a good job doing a light that can push that much lumens and still not burn your hand if u touch the head ,to me thats impressive and a small shitty fan wouldnt do much and thats why they scrapped that prototype with built in fan from last years.

I mean imalent dx80 throws alot more lumens yet the x9 is far bigger and pushes less so to me this is a way better light.

A full 3minutes at 25,000 lumens before stepping down…

I’m OK with that.

:+1: Me two!

When it comes to heatsink fins, air circulation plays a major role and mass is secondary as it only soaks the heat, no airflow means little heat transfer. Without ambient breeze even a small fan can make a huge difference. IMO the DX80 has a very poorly designed heatsink solution, they enclosed a finned aluminum heatsink inside the body, which makes no sense. I do hope Olight did a good job with thermals in this light and push it hard, most of their lights are stepped down way earlier than they should.

what does that say to u ?

here’s the problem the Acebeam x70 is not available yet… and doesn’t look like its going to be for a while

Olight is an overpriced hype machine. I have never handled one that I thought was worth the money.

You nasty man ! … they make a bunch of good lights

Hmm can’t say the Olight is better till you do a side by side comparison…. I’ll have both this coming Monday… and I’ll go to the field and test them out…

FWIW, I was talking with an Acebeam dealer yesterday and he said “The X70 is at least a month out”.

More than that I”ve been pushing several dealers and called Acebeam themselves and spoke to some reps… they gave me nothing other than they are still testing…etc…

If they are still in QA … that’s probably closer to end of year or 3-4 months out…

CNCman · 2018-06-10T18:52:40.000Z

I’m new here, so can someone please explain how 6 x XHP70.2 led’s can run at 25,000 lumens for any length of usable time without stepping down amps to protect the leds from “roasting on an open fire” ? Also the same question for other similar flashlights.

And if so, it’s worth $450.00 , I guess…

BlueSwordM · 2018-06-10T20:22:55.000Z

4200 lumens is actually what an XHP70.2 does at stock power levels, at 30W

4200 lumens x 6 = a bit more than 25 000 lumens.

It still is producing 120W of heat though, so the heatsink behind the LEDs must stay below 60C before stepping down at 3 mins, meaning it must be quite large and heavy to do so.

It is a lot of power, but it is easily doable.

Had they kept their active cooling, I would be that thing could actually do 15 000-20 00 lumens indefinitely.

mortuus · 2018-06-10T20:26:14.000Z

hehe i do wonder how hot the acebeams x70 will be with the fans running or not after a few minutes thats quite some heat to handle , and olight said on facebook if i remember they had no intent winning the max lumens race, instead they focus on safety and that stuff.

BlueSwordM · 2018-06-10T20:31:22.000Z

How hot?

Well, being a 40000 lumen light and having 12x XHP70.2s, it must be pushing out about 3400 lumens per XHP70.2.

Knowing that an XHP70.2 consumes 22W at that power level, it means that the light is consuming at least 270W of power at max brightness.

Either it is still going to step down after a few minutes because it is producing the amount of power of an overclocked 8 core CPU consumes under a beefy actively cooled heavily finned heatsink, or it must be running the fan at like 5000RPM to maintain sufficient airflow to keep the LEDs cool, meaning it would be a noise monster.

Cool light though still.

atbglenn · 2018-06-10T20:33:02.000Z

I love this new Olight, I’m just not cool with the price.

CNCman · 2018-06-10T21:35:37.000Z

Ok, that’s very interesting, because I want to built a light and had many ideas go down in flames so far. Looking at charts trying ( guessing ) to figure out what is going into the inside before even starting on the outside is hard to do without some Help from you experienced people here at BLF. So if , say for example, 1 XHP 70.2 NW led at 30W ( 3.0 amp ) will produce over 60c. What i need to know is approximately the max temperature it will produce over 60c. I don’t think I can air cool the light I want to build. I want it to run the battery down before heat step down. Does anyone know where I can find some info or can you just tell me here is good.

Newlumen · 2018-06-10T22:31:05.000Z

Once again, price is the reason I didn’t buy this light… another reason is built in battery pack…

Of course they didn’t.

Manufactures are [typically] very secretive in regards to upcoming models, new technology, release dates, etc.,.

What made you think they would divulge that information to you?

Oh gee let me see like when I called Olight and they told me the release date; it’s in their best interests to divulge no secretes….

Now that’s funny!

Olight spent 3 years telling EVERYONE when the X9 would release… :person_facepalming:

I spent all my money on other brands. while olight is making x9r. Lol… not joking…
