My main interest is in the X1 Clone. If i can not get it, i will buy the original Jaxman X1 flood!
The Lux P70 looks interesting and it would be something for future projects. Side switch is sweet and the tube is not overloaded with designs. The head design is the same as the X1. One of the best looking lights (in my opinion). So its a no brainer if the price is right and i can find a place where i can get it.
Kaidomain has a new Nightwatch 26650 XHP70.2 flashlight. Compared to the other I posted above, this one is lighter at 260g and doesn’t have a side button and cost $44. This makes the one sold on Enogear a steal at a current discounted price of $35!

Looks like it’s a Manta Ray…with a 70.2 in it…
I found this light on Alibaba.com. Seems to have some serious heatsinking and 3 XHP50 inside. The only problem might be the driver with 3 modes and 3120 lumens. It should be a nice host even for 3 XHP70.
I just received it from Enogear and weighed it. It weighs a whopping 363.8g on my calibrated scale (Enogear site list it at 350g). Good thing is most of the mass is in the head, where it is most needed for heat dissipation. The head weighs 257.6g! Surprisingly, it doesn’t feel as heavy as I imagined but I guess it is because of the large size. It is bigger than the Nightwatch NA40SE, which weighs 212.0g and the Sofirn C8F 21700, which is known to have great thermal performance weighing 197.4g. I’m still contemplating whether to put a XHP70.2 or 4xE21A in it. I’m leaning more towards 4xE21A since this thing can probably handle 2,000 lumens indefinitely.
It does have mode memory except for Turbo where it starts at “off”. Turbo lumens at 1s is 2,710 lumens measured with the TA lumen tube. I have the NW version and the CCT is about 4500k-5000k. It’s hard to tell because it has some yellowish (above the BBL) tint compared with my 4500k and 5000k below the BBL tint lights that look alot purer white. I guess the CW version should make more lumens.
No doubt that this light built like a tank. 
Keep my eye on this one but need some reviews.
Ugh……really……must….resist….the……Nightwatch…IRA!!!
Nearly the mass of the BLF Q8 and driven with a XHP 70.2 to around specs. Probably would be able to sustain Turbo at 5 minutes even with the constant hot nights in my country (plus output in medium for a really long time).
Sounds like you have already talked your self into it :smiling_imp:
Let me share something as well……. I have no idea how good is it. Button looks funky but i suppose you guys have no issue changing it out.
A bit on the expensive side though. usd 42….so i guess nope i’ll pass.

Head 90mm Body tube 55mm
Length 207mm 1 piece design
Carrier choice of 1S4P or 2S2P
Driver supports 30-32mm diameter with 2mm thickness
Reflector 80mm dia 70mm depth
Weight 820g. That’s Astrolux MF02S weight. (hopefully most of the mass is built around the head part, from the pic it seems that it is)
I really have a thing for heavier/solid hosts and lights with decent built. No need to be top-notch, just usable and trouble free is fine. Especially if they are cheap or have good value. I mean, that’s the whole and original point for having this Budgetlight forum. :sunglasses:
Actually it comes with an XHP70. I’m considering buying a XHP70.2 80CRI 4000k N2 bin. This N2 bin is super hard to fine. Infact prior to Kaidomain carrying it, it is unavailable anywhere else.
I have been looking for just this! Thanks!
That’s not so heavy for a 4 cell. If you want the heaviest flashlight host, get the TR-J20. I remember reading people weighed it at 1.5 or 1.6kg without batteries. With those crazy amount of fins, it should be able to handle 10k+ lumens until the batteries run out. I only wish it ran on 4 cells instead of 3 so you can put in some XHP35 HI emitters.
I bought one too. It’s a nice 5A tint also, whereas the Arrow, Mouser, and elsewhere sell unbinned tints so you can end up with nasty yellow/green tint. The XHP70.2 4000k 80CRI M4 bin I got from Mouser is very far above the BBL and the tint is unbearable.
Oh those showerhead floodlights bring back memories! The quality is actually quite usable, believe it or not, and BLFers then did not have any issues with the quality.
I have a Trustfire X100 (7 x XM-L) which is 75mm diameter head, 3+1S tube design. It weighs 700g only though (3S tube) from my own weighing. The head of the TR-J20 looks more substantial though.

The problem is that these TF/UF/SFs do not install a proper ($:money_mouth_face: driver, all these lights were all not driven to its full potential. Of coz when 12pcs of XM-Ls are driven to its full potential, the whole package needs to be engineered properly for it to last, even if the head is spec-ed up to be a 2kg monster with crazy fins. The heat is still going to be phenomenal even with the TR-J20’s amount of fins. I do not think it’s going to be infinitely run even with a 2kg head, unless if the temperature is sub-zero and with a slight breeze, if not the electronics would burn.
Dunk it into a jar of water (till the base of the head, no need to fill her up to the top part) and it ought to be fine though, i have already tried with the BLF Q8.
Yes, TR-J20 = 单只重量1360g

Later i am going to bring out my X100 and my triple XM-Ls (Xtar S1/Fenix TK-70/DRY) to test on the variable voltage 30A PSU. 
Its been a while. I think the 26650 and 32650s are done for, 0 volts. 
Now where are my 18650->26650 conversion tubes.
Yep, the Trustfire TR-J20 “budgetlight host” is a beast, even though it’s very underdriven. I guesstimate it should be around 3000+ lumens, wrt to my 3S driven X100 and the current they both take.

Initial – 147.7

What? 10k for a few good minutes should be fine. :heart_eyes:
Strangely, the weight shown is different at every website.
Aliexpress shows it at 1,524g

I think it is reported to weigh on the heavier side. The aluminum shelf is measured at a whopping 1/4” thick. I think with the mass and surface area in the head, this should be able to handle 10k lumens for 30+ minutes. Even the DX80 can handle over 7k lumens fr 1hr 34minutes and it has a lot less mass and surface area.
My dream project would be to replace the LEDs with 12 quad E21A 4000k from Virence.com, which is very efficient. That would make it a super practical light for photography or any other purpose.
Maybe it’s on the heavier side then. Just being over 1000g = no joke man, regardless that it’s 1.3 or 1.5kg.
I saw a couple of those latest tens of kilolumens Acebeam/Imalent reviews on youtube, one was saying that on Turbo it’s doing 165 F (71 deg C) before stepping down………… so the “turbo/high threshold” might be a little different from what we’d personally expect from the more budget lights. Though the DX80’s lower output at 7k and 1hr+ is quite telling too (it’s gonna be ultra efficient at those levels)
eg on the BLF Q8 it is set at ~ 55 deg C, unless you change it to “timed” and push to 70 deg C manually.
Maybe it’s like what you have said, it shd be sufficient 30 mins 10k lumens run in cooler climates and the 70 deg C head temps/battery temps are not a big concern. A higher temperature delta between the host-air interface also means higher heat transfer rate to the air.
Personally i am not a fan of pushing it that hard, also is coz my country is in the tropics (always hot!) so the batteries are gonna be risky. The head part (electronics and LEDs), well, i am still ok with that. In much cooler climates, i suppose the battery tube area is going to be kept quite cool.
For me a quick fix would be that i just tailstand the lights in a mug of water, at least to the base of the, so at least for the battery area it helps significantly.
Your dream project looks cool, good luck……i always give thumbs up for efficient designs as they’d be so useful across many applications in reality, though that 1-2 pocket rocket hotrods for ultra specific use might interest me at times as well.
Or maybe put it this way, i prefer it to be pushing no more than ~ 1500-2000 lumens for every 100g. That’s for the mass aspect. Not only for the first cold start turbo run, but also subsequent turbo runs from an already warm state coz you have been using the light already and need a turbo, host already at 40 deg C. Heat dissipation via the air is added bonus of coz.
In my case and temperature, 3 mins (most times 2 min 40-50s) is what it gets the 400g BLF Q8 5000lm to 55 deg C thereabouts.
