New XP-L High Intensity Emitter

@ smaller lights

Great news! Now some mods have to be postponed for a while. I hope for the XP-G2 version too :-)

Side by side

0.35mm protective layer over the die.

…must be secretly a member of BLF!

I am talking about for example Uniquefire, and i am sure countless other flashlight manufacturer, that don’t dare release a light out of spec. It is for those more conservative parts of the industry we need Cree to acknowledge, the very real possibility & reality that when using a DTP copper mcpcb, the Cree led’s can be driven much harder within safe parameters, than the current max spec of 3A.

We have the High Density & now High Intensity, Now we need the next step the High Output Cree binned Emitter. With for example fatter or extra bondwires to share the load, i suspect we can drive these led’s even harder but we are limited by the bond wires that burn up much sooner that needed.

Damn, I just recently ordered regular XPLs :expressionless:

I’ll buy them from you at half price with free shipping! Depreciation, ya know… :stuck_out_tongue:

Awesome! From the announcement it looks like there will be an entire line of emitters without domes. This will be a huge time saver.

How about we swop, i’ll give you 20 domed XPLs and you give me 10 Cree dedomed but the offer is open next 24h only :stuck_out_tongue:

I don’t have any de-domed to give you, or I’d be on it! If you’re serious, I’m sure someone here would be happy to take you up on that deal. :wink: Now, if you want to send me the twenty domed and give me a couple days to de-dome and send ten back to you, I’d be happy to do that for you! :stuck_out_tongue:

I feel the same way. Now I just need to order a Meteor 43 and 12 of these new domeless XP-L!

And hopefully all with way better tint than our manually dedomed XP-Ls!!!

RMM… please say you’ll have these in stock next week :heart_eyes:

It looks like the widened optics would still be needed for the XP-L high intensity ones. The highest bin listed is a V2 - a straight droppage of 3 bins which could match the results we've seen de-doming.

Well, I'll get 'em as fast as I can, but there's no ETA at the moment. I was the first to get the U4s, but I doubt that I will be the first here as well.

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.
