70.2 IMHO It’s all in the (bad) re-flow too much heat during the flow, or not enough solder with the ones I maimed/killed, never killed a 70 unless I was doing a total clean de-dome breaking bond wires. The 70 is a really tough emitter compared to the 70.2, but what do I know…it’s just from my limited non scientific experiences….
I sent the pic and link to this thread to some of my friends. I personally will not be getting one, but maybe they or some one I know will, so I might have a chance of handling one or two, Pat/Ross are you lurking… 
It’s a crazy beast, hope it works out well for Imalent and their customers…… :+1:
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 :smiling_imp:
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.
R90C vs MS12
R90C
MS12
Oh the color rendering is quite a bit better, and tint shift is reduced by so much. Really like it now :+1:
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.
they sent a few to Chinese reviewers/buyers at first
but I get you that answer ;)
Yeap… i seem many xhp70.2 failed.
holy moly!
video comparison of some lights including
Emisar D4 / MT35 / L6 / MT07S / DX80 and MS12
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.
Cool video. The last two are monstrous.
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.
Wow very impressive!
Would of liked to seen the R90C in the mix…. I think I might/would be interested in that one….
the tester did only buy the MS12
btw
I got the groupbuy pricing :D
hope I get the pages done tonight before leaving to Cyprus ;)
How about the R90c? Im waiting for the x70 instead of ms12.
