xml2 announced!!!!

We will see them in lights in approximately 1 to 52 weeks. The XP-E2 and XP-G2 haven’t been adopted that quickly, so it could potentially be a while. I don’t know if that is a supply thing or what. With so many XM-L lights out there, I would think there would be a real drive to adopt the XM-L2 quickly whereas the XP-E and XP-G aren’t used as widely anymore. The Cree datasheet lists all kinds of tints and brightnesses, but I can’t imagine all of those will be available that quickly.

XM-L has more cache than XP-G. I think the premium makes will rush to adopt the XM-L 2 because customers will be asking for it. I plan on holding off buying anymore lights until the XM-L 2 comes out. I have enough to hold me over for a while.

This sounds like a good quote for someone's signature line! We'll hold you to it Speedsix! Remember - NO MORE LIGHTS! :)

Without proper driving XML2 doesn’t mean anything.
s. does this means cheaper XM-L T6 and U2 :slight_smile:

With the 0.05 lower voltage requirement will a new series of drivers be needed or offered, or will the current ones work?
Also, whether it uses the current or new driver will it give slightly more full power output on the same battery?

The current drivers will works just fine since 0.05 volts is well under the ripple and noise of the Chinese drivers.

However, the higher voltage/current probably will be noticeably brighter under direct drive.

When comparing the data sheets i noticed the xm-l forward voltage graph is at 25ºC and the xm-l2 voltage is at 85ºC
What effect does higher temp have on forward voltage?

So it appears to be that an XM-L2 is basically 2 bins higher rated than the standard XM-L

So an XM-L U3 = XM-L2 T6 … More or less.

One more way to look at it:

Since the highest rated bin currently listed for XM-L2 is a U2, then basically we just got an XM-L U4, wish a little different markings and appearance.

I compared the datasheets and the new XM-L2 seem to have marginally lower output?
679 vs 692 for a T6 at 2A

but lower Uf is nice!

edit: ok, i just realised the XM-L2 is at 85° vs 25° :wink:

if the xml2 behaves like the xpg2, it is not only a few bins brighter, but can also be driven harder before output is levelling off (so where did they offer the 10xamc7135 driver again ).

which might be the BEST part - no more BS’ing by claiming U3 but producing T6 output…(not that it has happened to me…)

edit:well, not entirely - they can still BS xml2 bins….but we’ll know for sure it isn’t xml…

wow its a good thing I did not buy too many XML lights recently, me want haha.

I wonder how long till a p60 dropin? or someone like crelant will adopt them

Wow. And “they” said it couldn’t be done……

No solder pads on the topside :frowning:

The lower forward voltage is great news, although that may be a result of being binned at 85C (higher temps result in lower Vf).

I just thought of something:
When the Uf is lower and we drive them with a linear regulator (AMC7135) we would in fact have more voltage burned off by the regulator.
Therefore the driver will get hotter……

am i making a mistake?

Unfortunately not.

I think it’s time for BLF community to make our own
(buck) driver design that will be more efficient than linear 7135 based drivers. Most of serious users are by now familiar with soldering iron and have AVR programmer so this should be a decent base for further diy projects.

But then the LED itself is converting 20% more energy into light, so that will get less hot :slight_smile:

Who do you think will carry the new XML2 bare or with round base first? Hope I can get the highest bin in a nice tint like the 2B

I wonder if this is the reason Thrunite was blowing away the TN31 inventory…Hmmm
