Just received the above-mentioned light engine for my old faithful Haiku XPG. Did a heart transplant and compared it to my XML Haiku and my Warm Haiku...of course, I own a high CRI Ti Mule, but that is a different beam, so I didn't include it here.
Everyone has seen a Monopoly board, right? Sadly, these are only iPhone pics, but you can see the difference even in these.
First up - the 6V Haiku XML - I love this light, but there is definitely a slight green hue to the board
Then the Warm Haiku - one of my favorites - but a slight brown hue...
Now the High CRI Haiku - I didn't quite line the photos up the same, but the corner of the board tells the story. To my eyes, the color is dead on the money.
I wonder if this light gets enough respect? Who knows - I don't know how many Don sells...oh, sure, it's 'only' around 80 lumen...in this day of 'flamethrowers' it's easy to dismiss lights under 100 lumen. Yet the holy grail of McGizmo lovers seems to be the LS20, which in stock form is roughly the same output - or the PD-S, which, too is about the same output. And although I'll probably stir the faithful, the beam quality on those lights does not even come close to this light.
Quoting Don in this thread referring to the Nichia emitter:
"The LED also works well in the Haiku resulting in one of the best beams I have encountered and of course purely subjective and of my opinion."
I enthusiastically agree. If you have considered one of these but have held off due to concerns over output, etc., you might want to rethink it. I have my new EDC!!
Bravo, Mr. Don!
