XM-L U2

Pulled the trigger on this 5-mode U2 a few minutes ago.  http://www.kaidomain.com/ProductDetails.aspx?ProductId=11254 

I prefer a non-flashy 3-mode but that is the only low voltage U2 they had.  I've heard some bad things about Kaidomain so, hope they do me right.  Anybody tried a U2 yet?

I've been looking at it, but like you I'm not fond of flashy modes. And as usual, KD doesn't provide much info.Yell

But wait! You'll be able to tell us all about it before toooooooo long...Laughing Hopefully it will have memory, allowing you to avoid those flashy modes somewhat.

Guess I could have did a search.  Yep - gonna do a review when it gets here.  So Tas, was that a Solarforce XM-L on the left?  (looks like my SF XM-L)  I'm curious how it will do with a smooth reflector.

on the left. Just an Ultrafire H-M-L drop-in in a 502B ($5.63 from T-mart with charger and battery)Cool

I'll swap reflectors and have play later.

Y not? I dipped into my savings..........not yours.

More to the point "why" isn't a sensible to ask on a flahaholic forum.

Is a better (to me) colour than the T6. I've got three of them, two drop-ins from MF and a 2X18650 light from KD. They all have a slight green tint. The U2 is much whiter.

It's dark at last (though a bit too much moonlight), but with a quick outdoor comparison against a wall at ~40m......the U2 is quite a bit brighter than the T6.

Same huge hotspot, but noticeably more light.

I guess that this dropin would fit the Ultrafire C1 without any other further mods?

So Tas, do you think it's a legitimate U2 emitter?

LOL, the good ol' "it's quite a bit brighter than a T6" is probably good enough for me. In budget world, that means it is a U2.  LOL

If only Cree would label the bloody things, then we would know if we were getting the real deal or not...bah!

 

Sadly we're not who they are making them for...they don't care about us, those big meanies Silly

Guys,

  I just finished up a new build based on the XM-L U2(2S) that I recieved from Cutter.  Without spoiling anything I can honestly say the color on my samples is pure white, and output definately exceeds the T6. This is my new favorite XM-L flavor.

Just keep in mind that if the U2 is packaged in a drop-in, it may be limited by whatever driver is used.  I think that may be why some aren't excited about it.

Match, that's encouraging feedback. It may be time for me to pull the trigger. Keep us posted.

Sounds like it's time for a newb like me to get to get my feet wet and learn how to swap out a driver from a drop-in. Any suggestions for a replacement driver Match?

Any 8xAMC7135 based driver would be a fine choice.  There's one here, here, or, here. A single mode option is here.

I have got a XM-L U2 1A.

In comparison to a T6, hotspot is not brighter, only spill is little, little bit brighter.

They are labelled! on the packaging. The problem is where we buy them from don't provide us with photo proof of the label, or include any of it with the product. The codes are too long to print onto the emitter in a human readable language and size anyway.

Hey, Andi, what tint does it have? What T6 do you have? UF 3 mode from MF?
