I find this an interesting contrast with the DT70 or DN70; those lights are really bright, really compact, and really light. So the lights step down fast. The DX80 on the other hand is really bright, really compact… but really heavy (this is good in my book at this moment). Interesting… :sunglasses:
make me wonder what other lights in the new DX series may be in the future.
Maybe something that is bigger and does more than the X65? Seven XHP35 in two-inch diameter non-overlapping reflector wells? Head diameter would be huge, but that is needed for huge beam performance. Such an item, and this item are in my area of interest.
Before I forget, I always need to remind myself: I can always throttle back to middle mode for heat management and longer run time.
Some new pictures (nothing spectacular) can be found here: http://www.fengyunbike.com/thread-103122-1-1.html
According to one picture, the light has 8 x 3000mAh battteries, so this light probably uses the same batteries supplied with the DT70/DT35 (= protected 30Q).
Somehow this light is listed on Ali for 425$
Yeah you are right, just checked aliexpress. $425 is that for real? I am gonna pass on this way too expensive.
$425? That’s insane even if you get a perfect one.
I think this kind of stuff happens regularly. A product is not for sale yet, so a vendor tries to get as many pre-orders as possible, not always letting customers know the product is not for sale yet. Since the product is not for sale yet, a google search leads quickly to the vendor as well. If I’m not mistaken MSRP is $375,- and knowing Imalent prices, this means that if you wait a few months price will drop with coupon to about half, i.e. $200,-
Haikelite is said to be working on 18000 Lumens flashlight, i hope that is correct since their quality so far is better, my DN70 is working perfectly fine though no complain here, i might get the the DN35 based on that.
Well it’s listed at Banggood for $380,- IMALENT DX80 8x XHP70.2 32000LM Super-Bright Outdoor Suche LED Taschenlampe 8 Sale - Banggood Deutschland sold out-arrival notice-arrival notice
Mode spacing changed, and is actually really good 120, 500, 1500, 5000, 13000, 320000. So far so good I’d say. 
nice but what are the actual runtimes on higher lumens?
Is t 30K lumens for 10 seconds then stepdown to 2K?
Now that hyper lumen lights come to market I feel it is more how long higher luns modes can actualy run are more important then a short hyper burst
from the commercial video we can see the imalent DX80 has CPU style heatsink fins inside the head, not sure if the cooling is active like Olight X9 or not.
i think we should be making our own stupid bright light, BLF style! :cowboy_hat_face:
Well the thing is a nice 1.2 kg. My wild guess would be between 30 and 60 seconds before step down.
THIS, if this steps down to 2000 lumens after 20seconds I would see it as a 2K lumens light, funny, K lumens is what the Q8 can sustain till cells are depleted, so for this I would expect more.
And enclosed heatsink won’t help that much without a fan, air must be able to freely move especially in passive solutions, so it looks cool and all, but without a fan and good vent holes I dont think it will help much (lol and adding a fan makes it much much harder to have a nice waterproofed light (I have been looking into this for the Q16)
There should be vent holes on the side for hot air to escape. I’d say such a design is so much better than a conventional design used in flashlights; it’s an extra feature. X65 has a conventional design and is doing pretty ok. The little X80 has 25000 lumens and is super tiny… Output on the other hand might be less than claimed, so maybe 25000 lumens or so?
Of course it’s going to step down fast. But you also have the 13000 lumen and 5000 lumen mode; great output levels!
Edit:
I think it’s going to step down between 2500 and 3000 lumens.
Soon we will see fans being installed for stock lights.
Put three fingers with a small gap between them in front of the other arm and blow on them, feel how little air goes through and around.
Now place your finger tips on your arm so the fingers are round, like the little vent holes on this round head, blow, even less air goes through and more hits your arms above where the fingers are placed.
Water and air will go the way of least resistance.
So the small fin wide gaps on this light are only good if actively cooled I think.
Resistance increases as you apply pressure by blowing. I think that is a difference with the cooling principle of this light, which is based on convection (temperature difference, ambient pressure). A small breeze when walking with the light outside should make a lot of difference.
