Ok, finally got the engine and took this photo. Now that we have a better view, XPG or XPG-2?
Any way to tell whether it's a Neutral or Cool without installing it?
Thank you for all the support!

I would also think cool tint is more likely, presuming it is the stock emitter, but ... I've already been fooled once in this thread, lol :thinking:

Looked a bit big to me to be an XPG too, but that's how it was advertised so I wasn't sure. Makes a lot of sense now. Either way, I'm glad to own it! Thanks for all the great input!

That will fit a haiku, sundrop or mule. Don't try that on a makai though.


It will work in a Mule or SD as is, but if you want to put it in a Haiku you will have to make sure you have the appropriate reflector. I think certain reflectors (for the 119 and XP-G and XR-E) have a smaller opening and there could be interference issues with the larger XM-L.

Yes. Nbp is right. The haiku uses 2 types of reflector. One accommodates the larger emitters like the xre and XML. Another does the smaller Nichia and xpg.

Thanks folks, this is very important information. Greatly appreciated!

The philosophy of these flashlights does not require the absolute latest cutting edge LED to be fulfilled ... would be my sense of things.

Is there a technical reason Don doesn't use modern emitters?

Wow, now there's an interesting question?!?! Immediately my question in return is what constitutes a "modern emitter" to the point what I use are no longer modern.

But I can respond to a more general question as to why I don't offer every emitter that comes along and every bin available of every emitter that comes along. And the reasons would be both of a technical as well as practical nature.

The Mule and SunDrop can easily be host to any number of LED's and only require that the LED meet certain physical size and power requirements. If size and power requirement are met then the only technical issue is that of an appropriate MCPCB upon which to mount the emitter. If this involves a new design and run of MCPCB's then that is a practical and financial consideration. Sourcing and purchasing a minimum required lot of the emitters is also a practical and financial consideration. Confusing the potential users and buyers of my light with an added emitter choice is also a practical consideration. There needs to be a significant difference in any new offering to allow for a clear path to a final choice of emitter by the user.

An interesting aside here I think is to consider over the years how some light manufacturers identified their offerings by emitter identification itself and how some manufactures likely targeting a less informed market avoid any mention of emitter make or model. There was a time a number of years ago when I was more aware of what was coming out where some of the offshore manufacturers were coming out with a new light every time a new significant bin of LED model came out and basically pushing the new light based on this new emitter, alone. I don't pay any attention to what these CPF focused manufacturers are offering these days so I don't know if such a transient or fleeting difference is the fuel for their marketing or not.

Regarding the Haiku, a new emitter might well require a redesign of reflector for decent light distribution and that is a technical as well as financial consideration of significance.

I have evolved into a niche here on the forum where I have been able to offer lights I believe in, to folks sharing the same interests and priorities. Certainly as time has moved on and the forum has grown and matured, it has become more and more difficult to "compete" as new entries and offerings, often little more than imitations, have been added to the mix. To me, the emitter and converter which constitute the light engine are the heart and soul of the light. But a light is more than just heart and soul and a good heart and soul in a good host can be timeless in terms of utility and value. The Haiku has been offered now for a number of years and I wonder how many other lights out there have been offered for as long. Granted I have changed the light engines over time and added new options as emitters have come available. And more importantly, new emitters when they offer something either better or of significant difference.

My goal is to build lights that will offer utility well beyond any time frame required of them. Such a goal is inherently contrary to value being based on "modern". My goal I guess would be better considered as timeless in value?!? That's not to say that I don't strive to use contemporary LED's at the time of build.

This question was posed in the Haiku XP-G thread so perhaps it is in reference to the new XPG-3? If that is the case, I have no doubt that I will most likely be offering the XPG-3 in lieu of the XPG-2 and possibly replacing the Nichia 119V as well, but not in the near term. I need to actually be able to purchase these emitters of a bin that surpasses that of the emitters I presently have on hand. That these emitters can be driven at a higher maximum current is of no advantage in my light engines at present.

Thanks for the detailed response. I should have perhaps said newer rather than more modern. I was actually thinking of the XP-L HI rather than the XP-G3 for the Haiku but I know nothing about the technical challenges posed by a different vf or die size requiring changes to the light engine or reflector. I also have no idea whether the XP-L HI actually produces as much light as the XP-G at .6 amps. I meant no disrespect to your work. It is gorgeous as well as utilitarian. That is a difficult combination to achieve.

I love reading Don's posts on design philosophy. I'm still waiting for you to write a book. [emoji2]

nbp: great idea!

TRUE: Don is always thoughtful and informative, isn't he? (He's DEEP!)
I've always thought of him as a "Man Of Nobility".
We're lucky to nave him on CPF.

BUT - I never thought of hin writing a book!

Yeah Don, get on with it!
I suggest a Bio, with torch design entwined, your inventions, and your love for the Sea (Love-Of-Life too), your philosopy of Life, and Love of Nature.

I'd Love To Read it!

Please forgive me for reducing the quote, but I just LOVE this part! .....and I LOVE my McGizmo flashlights!
