I can see the bones in my hand!

Kawi, order me one when you get yours.

A tangent question on XHP70 vs XHP70.2. have any of you guys that have modded with XHP70.2 experienced the emitters failing? I have read of several cases with the DX80 where 2 of the 4 dies lose connection and go dark. Similar to the common problem with XHP50.2. it can be easy to miss because 2 of the 4 dies would still be putting out a lot of light. You would need to look at it with eclipse or welding glasses to spot the dark dies.

It’s a crazy beast, hope it works out well for Imalent and their customers……

Well dang, am I gonna have to build something in an attempt to see those numbers? I have 50 Samsung LH351D’s…

@DBCustom, perhaps these MCPCBs could help you build something special in the 7070 emitter size with the LH351Ds:

So, you’re thinking that if I bought 12 of those and left them attached and flowed 48 Samsung’s for a 48 emitter mule that I might see some serious great wall of lumens output? Probably pushed by a 4 parallel set of 21700 30T’s?

Edit: I have multiple 15 count sheets of SinkPAD’s that the SST-40 will fit on. Wonder what 45 of those would produce with a bank of, say, 8 parallel 30T’s?

1. Hmmm. With nice high efficient optics from say UCL, you could perhaps reach 50k lumens with 48 of these emitters

And yes, you could push 500W out of these 4 cell of Samsung 30Ts. I just wonder how you could actually reach that amount of power without melting copper on your way to the emitters if you take the 3V variant

Seriously though, it could be done. I would just recommend to take the 12V MCPCBs to lower current as much as possible.

2. Yes it could be done. However, you would need say… over 130A of total current. How would you do this?

Multiple FET drivers to drive banks of parallel emitters from the same power source. I mean, if I was going to… it’d effectively be like combining multiple lights into a single host. Like 4 Noctigon M43’s into one unit.

But of course, they are doing this here in a single large head with a cooling fan and nice charging set-up, so perhaps Imalent is onto something. I personally find the 9x XHP-35 very intriguing. If I were to buy one of these 3 it would be this one.

Oh the color rendering is quite a bit better, and tint shift is reduced by so much. Really like it now

Martin, do you have those two lights with you or were you sent those pictures?

I’d really like to know where air goes in and where it comes out.

Yeap.. i seem many xhp70.2 failed.

But i dont get it, both olight and acebeam use xhp70.2 in their lights? and the x70 will use as many emitters as the ms12 so imalent couldnt get it right and chose the older emitters ??

cool video u can def see alot brighter flood then dx80.

Took 2 still screens from the video DX80 vs MS12,

I think we are near the end of the evolution of flood lights.The missing part is the cooling capability which wants updating.

How about the R90c? Im waiting for the x70 instead of ms12.

Gonna have fun taking this down the Dangerous Place, how many lumens is the side light putting out?

Sell BLF GT to fund r90c?

but I get you that answer  

DX80 vs MS12: After one year, the DX80’s 32000LM’s first monster status has finally been replaced. The 53000LM’s MS12 is more than DX80, whether it is from parameters or measured performance. The MS12’s light cup has a larger diameter and a slightly larger depth than the DX80. The effect change is that the center spot is slightly smaller than the DX80, and the whole is more concentrated and the long-range is stronger. At the same time, the flood angle is basically the same as the DX80, but the brightness is higher. However, from the perspective of my personal scene, in fact, the visual difference between these two lights is not so obvious. When I open the brightest moment, my heart is silently saying “I X, I am going” and so on. It is the same shock, because the sensitivity of the human eye to high-brightness light sources is gradually reduced. I don’t have an integrating sphere. I can’t test whether the MS12 is virtual, but from the video shooting results, the MS12 is indeed brighter and more powerful than the DX80.

Ahhh this is you..dont scare me again..lol..BTW this is ThatCrazyFlashaholic 67.

It seems daft pumping over 1000 lumens down a thin snicket but tbh I enjoy watching my videos back and sitting at a table talking about anodisation and knurling for 15 mins isn’t for me.

A company has just asked me to start off indoors and review their light in the style of Adventuresportsflashlights, I’ve told them to **** ***, they can send it to Blippi.

I tried Google translator with the Chinese buyer-tester and found the following.

TBH I’d prefer to sacrifice a little candela and graduate the hotspot into the spill a little more. Even though it had god awful petals the DT70’S hotspot isn’t that noticeable and it gives the impression of the DT70 being a lot brighter than 13000 lumens, it helps dissolve tint shift too.
