Fyrstormer's Evil Labs presents: Hi-CRI Haiku

[fyrstormer]

So I got this Haiku in the mail the other day...

...and I got these LEDs today...

...so I made this:

Now my Haiku has a buddy. :buddies:

Re: Hi-CRI Haiku

No way. How comparable would you say the output is? I was just thinking about how a 3S Sundrop with the output of a Haiku would be awesome/perfect for me.

Re: Hi-CRI Haiku

Read my mind, ninemm. While you were posting your question, I was doing a comparison with a SunDrop light engine installed in my other Haiku. SunDrop is on the left.

Re: Hi-CRI Haiku

What led did you put in it?

Re: Hi-CRI Haiku

What emitter is that? Seoul P4? Looks like the output is about the same as the sundrop light engine with a higher color temp.

I love the Haikus. They are just gorgeous lights.

Simply Beautiful Mr. Stormer!



Great Job! Any idea as to the output on high? And possibly a group build? I know I might be interested.

Re: Hi-CRI Haiku

The emitters I got from Tekno_Cowboy's group buy a few weeks ago: http://www.cpfmarketplace.com/mp/showthread.php?t=196673. The bag is tagged "T1STAI", which as I understand it means they are slightly dimmer than T2's and slightly cooler than SS's (roughly 4300K instead of 4000K; yes, a higher temperature is cooler, don't you love combining modern measurements with antiquated terminology? ) I don't know what the AI stands for, possibly something to do with the type of carrier package?

The color temperature is noticeably warmer than the Nichia 083 used in the SunDrop, but the color rendition is just as good to my eyes. I'm actually not a big fan of warm emitters as a rule, but the high CRI on these means it renders the healthy green grass in my yard just as well as the dead brown grass, which is my usual eyeball benchmark for LED tint. The output is noticeably higher than the Nichia 083, as can be seen in the second set of pictures I posted, which is expected since it runs at twice the current.

I have four of these emitters left, plus a T1SS that I got as a test-fit sample; the installation was relatively painless, it was first time I had the chutzpah to de-solder an emitter from its mounting board, but I want to play around with the focus a bit since the reflector wasn't actually designed for this emitter's radiation pattern.

Well dang! This might get confusing when I introduce the Haiku High CRI and Mule High CRI. :shrug:

I'm not confused by that at all. So when might that release be pray tell?:naughty:

Re: Hi-CRI Haiku

Well, that sucks. Stupid databases and their failure to be perfect at all times. :sick2:

(everything I need to know about Oracle, by the way, I learned by running headlong into a wall while trying to escape at a dead run.)

So anyway, as I said before the Matrix was tweaked: I fixed the focus issue with the P4 LED; it looks like the centering ring doesn't need to be altered after all, so it can still perform its original function with an XR-E LED as well as acting as a spacer with a P4 LED. I can't really do a group-build because my supply of LEDs is dependent on the inclination of others to run group-buys of them, but I have 4 more LEDs so if anyone wants this done, send me a PM and we'll work something out.

Can't help it! I'm a mule fan (with an ultra low mode ).

Nice mod fyrstormer :thumbsup:.
