Concerning the LEDs: I would consider offering the Nichia 219C (Datasheets: cool-white and warm-white). It is the third generation "219" LED with an even higher efficiency. It has the same footprint as as older 219s and all the Cree XP-LEDs. It is available with and without high-cri (the 90CRI version will be available soon). Is has a much, much lower Vf compared to the XP-G2. In terms of lumens/watt the 5700K 70CRI version is more efficient than the cw XP-G2 S4.

The new XP-G3 is more efficient than all of them, but it has a lot of problems. When using reflectors the tint is not uniform across the beam (blueish spot, yellow spill).

I've used a 4000K 219C in a Haiku and Mule. Not bad but the hotspot in the Haiku was kind of weird, the peripheral of the hotspot was a different tint/intensity to the centre? It was powerful and threw well, only noticed the odd spot white walling.
Put a 5000K XPG3 Hi CRI behind a biggish smooth reflector and it was horrible, but behind a Ledil boom it's actually pretty nice. Haven't put one in a McGizmo.
Latest mod, XML2 U2 3D (reflowed from stock XML) into a Haiku after swapping XP to XR reflector. Nice tint but I'm sold on the 119 (V) or XPG2.
I can't see Don mixing it up here, he has his system and ways. I certainly can't disagree with him and think his LED selection is spot on really.

The XP-L HI led makes a very nice beam in the Haiku! Very similar to the XPG2, I believe. Driven at 1.4 amps it puts out like 400+ lumens!

Re: Haiku

I have an original Haiku and was wondering what size the o-rings are. Mine is worn out and needs to be replaced. Every one I've tried is too big or too small.

Which one? The one on the body threads where it contacts the head?

I assume it's the one that nbp is asking after and that is a #017.

Right, if that's the one he needs I have a whole bunch, I could drop a couple in an envelope for him. If it's a different one he'd have to source some.
