Ah drat!
Many times i have been configuring my dream light (D4v2 with tint ramping) on your site, but many times i did not order.
Now i finally ordered and accidently selected the wrong LED on channel 1 !
Hopefully Hank will read my message in time!
The FET driver is used with the SST-20 emitters.
I purchased two more DM11s, one with XHP35 HI and another with SFT40. I ordered another throwy optic for the B35AM light I have, but what I got was another floody optic identical to the one I already had… so I can’t test the throwier version.
For all three lights, I tested output and intensity both with the included optics, and the floodier optic that came with the B35AM. I was concerned that my numbers were off on the Nichia light since every other reviewer had lower measurements on turbo, but after testing multiple times with different cells and everything, I consistently got over 1600 lumens. I am wondering if the floodier optic might possibly be increasing the output on my light somehow.
B35AM: 1,650 lumens
Floody optic: 14.7 cd/l, 24kcd
XHP35 HI: 1,600 lumens
Floody optic: 12.4 cd/l, 19.8kcd (surprisingly low)
Throwy optic: 40 cd/l, 64kcd
SFT40: 2,200 lumens
Floody optic: 24.8 cd/l, 54.5kcd
Throwy optic: 68 cd/l, 149.8 kcd
While I don’t have the modified optic for the Nichia, I tried the throwy version in my B35AM light anyways just for fun, and when fully seated, it does indeed have a nasty donut-hole in the center - I didn’t measure the intensity. HOWEVER, I found the optic very difficult to seat into the post holes, and found that when it wasn’t fully seated, I could still screw the bezel down fairly tight, and it produced a very nice clean, tight beam with 24 cd/l and 40kcd total.
So you are saying that the optic performed better sitting higher ?
Yep
Any chance the B35AM emitter/ MCPCB and driver could work in the K1?
In my two DM11 samples (WE & B35AM) I didn’t notice (but didn’t specifically look for) any differences in the optics. What I did notice was that the B35 version had little riser pegs in the optic leg holes in the MCPCB to raise the optic up. That seems to jive with what Lux is saying. There are photos in the emitter & beam section of my review. You can see the little red riser pegs and you can see the installed B35 optic sticking out further than the W1 optic.
Edit: I tried to find a way to copy the image URL’s to put them directly in this post but I can’t figure out how. They’re part of an image comparison and a slideshow in wordpress.
Email him with your order number and preferred build asap if you have not already.
I did and have to say; Hank is very fast, he already did reply!
Hank definitely sent me a green tint bin with the 5700k lh351d he sent me. It looks as bad as some olights I’ve seen.
Hmm. First post here is a complaint.
Yeah, he came here only to complain?
BTW, i.m.o. Hank is one of the most respected suppliers, especially when it comes to emitter types, tints and bins.
Looks like lightweaver regrets his choice.
LH351Ds reads quite bit greener than what’s what they’re supposed to according to their tint bin, Hank has Q2 IIRC, I have some Q1 from Convoy and in a beaded (very diffusing) TIR lens they can read between 0.004 and 0.0065, according to the bin they should read between –0.004 and 0.002, those are integrated measurements sure but still that’s a big difference, especially with diffusing optics.
Hopefully the Nichia 519A will be a better option at all CCTs (already the case at 4500K from Bob_mcbob test), and especially at high CCTs to replace the green LH351Ds.
I wish the 351D wasn’t that way, but it is. I had one batch of 5000Ks that when shaved looked okay, but I always felt the color reproduction was less than stunning. Rosy XPLs make more sense to me in a lot of apps. I have some 80 or 85CRI 5A3 XPLs in a triple that take the cake over any Samsung I’ve come across. YMMV.
Also hoping the 519a can take some amps. Waiting on mine to show up and test.
Here is a pic of the spacers that were in the holes where the optic’s legs normally go. They are almost flush with the aux pcb. DM11 B35AM, shipped about a week after release.
They are soft, feel like silicone.
Thanks for posting elendur. Is it just the pic or are they sort of irregular cuts of an o-ring? I’d expect something a little more precise. Maybe this is just a stopgap for now…
You are seeing correctly. I trimmed them down a little, even shortened a bit to make them equal length. I guess it’s good that it can compress a bit while screwing the bezel down?
In reality, as long as they are close in length, the glass should square up the TIR against the ‘squish’ of the spacers. Interesting solution
