Ah!
Not helping the bank account, or my mind guys!
I really want one of those BB Haiku, but I'd like a more floody beam like the XP-G gives...![]()
Ooops - not available yet...

I have resisted doing that a number of times now.
The original Haiku was not recommended to be run on high for long periods. Because the XP-G is being underdriven, does it run cooler on high ?

The drive level is the same to both the XR-E in the Haiku and the XP-G in the Haiku XP-G. The fact there is more flux from the XP-G makes me think there is less wasted energy in heat with it. The XR-E is being underdriven though in the Haiku and I am not aware of any real issue running it for long periods, especially if you are holding it and aiding in the thermal dissipation by doing so. The size of the XR-E and its larger heat sink pad make me think it is a better package in terms of thermal relief and indeed, it does have a higher max current than the XP-G.![]()

Any E.T.A updates Don?

Yeah, I am composing the wave offering in another window as I type this. In the spirit of full disclosure and regarding waves, I have been slow to get this offering launched because there have been day after day of good waves over here and I have been unable to avoid them or find the energy reserves required to work late into the nights after a demanding day of wave riding.![]()
I was also holding off hoping to be able to offer an alternative battery pak to the CR123 McClickie pak but alas, still vapor. (2xAA McClickie pak to be specific)
Since this thread is the foundation or source of information on the Haiku XP-G I think I need to post an observation or caution here.
If for some reason, you find the need or desire to remove the XP-G LE from the Haiku head, please pay attention to the 5x1 mm LED separator O-ring when you go to re-install the LE. This O-ring is not really captive either in the cup on the reflector or around the LED package. Gravity can cause it to relocate itself other than where it is intended to reside.

It's all good Don! I understand, I don't surf but I can relate with riding my Motorbike.
If it's a nice day, there's no point on calling me that day
Sorry for the consistent harassment mate!
Thanks for your understanding and compassion!![]()
You didn't waste anytime! (e-mail received)![]()

Your welcome!
Nah, I'm not one for wasting time... especially if it's a good cause![]()

Way to go Jared! I'm right there with you - as fast as I went, you were first and two more went in while I was sending my email to Don!
Don, looks like you've got another winner on your hands!
![]()
Thanks Dan!
It sure does look like he has another winner, that's for sure!
Yup, looking foward to this one!![]()

I've run my Haiku XR-E on high until the battery shut off, with no ill effects. I'm not supposed to do that? News to me. I thought the Haiku had good heat dissipation?
2AA clickie huh!? I thought I would never see the day! Definitely a good alternative!
Dude, you need to get out while the waves are still nice and the trades are relatively calm. Never know when it will get this nice again!
Hey Don, I posted your pics on the USN, started a thread over there. Judt thought I would let you know, and yes, I gave you credit for the pics.
Alot of those guys over there love your work, but dont keep up.![]()

I don't think there is a problem running the Haiku at full speed. I never heard of that.
There is a type of perfection that transcends the quest for lumens. Buying a $250 1-cell light for "lum factor" is like buying a $250 single malt Scotch for the alcohol content.

Have a look at the sticky of the Haiku, first posting from Don :
further on :I do not think the Haiku should be used for long durations on high and especially if it is not held in the hand for thermal relief...
So, Don warned us about it without saying we mustn't deplete a whole cell on high. Probably it gets close to the critical area (unattended), so that perhaps at 35 degrees (Celsius) it could go above, at 20 degrees it's safe.It appears that the light can handle constant on in high but that is not the intention of its design or expected usage.
The fact, that nobody reported ayet means probably that we shouldn't worry...

My way : From Maglite and drop-ins over Fenix & Co to the real things - Customs and Titaniums!
The first remark is aagainst high level unattended on a desk for longer periods of time I think.
Like you all said ... no problems reported, and I don't think there will be, the drive current is still reasonable.
This is of course IMHO and I hope DOn will correct me should I err.

Don's design are almost always on the conservative side with regards to current to the LED, thermal considerations, and his warnings to users.
Unless you are running an unattended runtime test on high during the middle of summer, outside, and in the dessert I wouldn't worry too much with the XR-E. BUT, as Bernie mentioned, Don is the last say in this matter.
Since there is no waranty, stated or implied, you guys can do what ever you want with these lights!
Seriously though, I don't believe you can harm the LED or circuitry in normal use which could include full battery depletion on high. But the ambient conditions can vary and to state with no qualifications that these or any other lights for that matter, can't be harmed is giving some of us way more credit than we deserve!
The light was designed to provide service and utility with all three levels of output and if one only uses high then the light is not being used as intended. It should be just fine but still not being used, as intended. I don't know if that makes any sense?

Makes sense to me.
So does that make me weird or something?![]()
If only I could go forward in time![]()
Haha!
