Imalent unveils R70C – R90C – MS12

Martin says that he was told the 70.2 have some issues so they went with the more reliable 70 series. I am not sure what they were referring to but that’s what they told him. Obviously, it’s not going to be easy to push the 70.2 to challenging levels when using 12 of them, and at under 5,000 lumens per emitter there just isn’t a problem. The use of 70.2’s in this light would yield even more than what they’ve tested, if indeed the 70’s do 53,000 then the 70.2’s would do more than that without changing anything else.

Now, are we going to pay $600 for a flashlight then buy 12 new emitters at over $12 each to upgrade it? Well, somebody here might. Somebody with deeper pockets than mine…

Edit: Several of us here have pushed the 70.2 to over 9000 lumens in lights like the L6, maybe even in the GT…

:D

LOL! That’s giggleworthy for SURE!

I can see the bones in my hand! :person_facepalming:

:smiley:

Kawi, order me one when you get yours. :stuck_out_tongue:

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.

that's the reason why they used the xhp70 .

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… :smiley:

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… :stuck_out_tongue:

@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. :slight_smile:

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!
