New XP-L High Intensity Emitter

I came across mention that LED color changes are known over time from operating where there are volatile chemicals (including from plastics or thermal compounds) that can get into the phosphors.
I’d guess the flat clear layer is to seal the phosphor (and perhaps that’s one reason people see color change after dedoming, though I’d be guessing on that).

That would be a good question to pose to RMM as I’ve read where he mentions using LED seal when he dedomes leds. RMM, can you tell a difference in the tint of leds that you dedome after using led seal?

Read the references — there are observations of tint change due to volatile chemicals that can get into phosphors — but the devil is in the details:
how much time does it take (and is that operating time while heated, or exposure time after some amount of heating starts something gassing out? which chemical, and which phosphor (many emitters use more than one phosphor). Oh, and what solder was used? what flux? what else is inside the container (flashlight head, for us)?

It doesn’t seen to be a simple easy issue.

I’d buy That for dollar! Heck, I’d buy a double handful of em at a dollar apiece! :slight_smile:

Seriously though, I’m in the line to get some as soon as they become available Richard, count on it.

:bigsmile:

Agree! Damn…

+1000!

But where’s fun in that :stuck_out_tongue:

Just to clarify, shrick wants 2 full reels :bigsmile: (1 reel is 500 pcs)

Double Handful x (+1000) = 10 x 1000 = 10 000!! I’ll take 20 reels then!! Yikes, I’m clearly having a hard time with Lumen-Sickness :slight_smile:

If these can go under unmodified triple optics, and if they come in a 3D tint, I’ll be wanting a bunch of them. :slight_smile:

Sort of like SBT-70 with lots of bond wires, something tells me that such emitter would be more expensive due to being able to take more current.

@Djozz:

Yes, but maybe this flat dome XPL is a good choice for a Uniquefire shorty Aespheric? :bigsmile: :wink:

yep, that is one them :-)

It will be the XB-H High Intensity. Forget the old generation. http://www.cree.com/led-components-and-modules/products/xlamp/discrete-directional/xlamp-xbh

This is great news. Such a good time saver and don’t need to be soo concerned about damaging a bond wire anymore.

I am with ToyKeeper. This in a 3D tint will be awesome.

You are right about max flux bin V2, i messed up when i checked the pdf before, i saw a CW V5 high density and thought i was looking at the High Intensity ones.

But isn’t it strange that the High Density ones according to cree only goes to V5? Is the High Density ones different than the old XP-L, I though High Density meant with the dome like the old ones :~

I hope not the XB-H looks at least according to Cree’s data cheats to have lower output than the XP-G2, and that is not even counting the newly released S4 flux bin.

XB-H
XP-G2

Any chance of the meteor to be sold with the new XP-L? Or Is it possible to order it with a blank, separated mcp? This is shocking news and I will have to re-mod at least 15 lights including A couple XP-L triples with modified carclos…

I wonder how many flashlight modding projects were suddenly paused and postponed with this announcement? 3 for myself…



Let's make an educated calculation.

XP-L V6 @ 50Celsius, @ 2A does 874lm (CREE PTC used for values), now cut 11% loses in the new XP-L HI = 777lm
777*12LEDs = 9324lm, now losses in optics and glass -12% = 8205lm.
Losses in optics and glass can be higher of course, I chose 10% for Carclo 10507 and 2% for the glass.

What we don't think about it is that if the Vf is higher than results can't be better at minutes later, a very important aspect totally ignored, when it is proved that it is not higher well then it can be ignored, we know that what CREE specifies for the Vf is often not what is found in reality.
There is no gains over dedomed regular XP-L (either lumens or candela) , just makes the tint good.
That is if it fits under the Carclo optics.

why you ruining our party? :party: :party: :party:

I’m joking of course. but seriously, I want to see if it fits under Carclo optics. that’s the question.
