Zebralight SC64c LE w/High CRI Nichia 219B R9080 $150

My prediction: All of Bob_McBob’s order attempts went through and he gets 50 SC64 LE’s. :sunglasses:

It’s interesting to learn indirectly via Bob’s trouble ordering them that the LE is apparently seeing very strong demand. That’s a good message to Zebralight that there is more to high CRI than a datasheet claiming a “2-step Macadam Ellipse.”

Maybe, maybe the will do their homework.
But after receiving this response I don’t think so. 0.03lm translates to 0.08lm, that’s a huge difference.

Invoices all sent out for the new batch of lights :slight_smile:

Update: I am currently building lights. My new method is to build one light at a time from start to finish, generally one or two per day at most. I do them in the order I received inquiries and sent invoices, and I will PM you when your number is up and try to send a couple teaser photos as well. I’m being more methodical about getting them done now so all current orders should be cleared in the next 1 1/2 weeks or so. Just watch out for a PM :slight_smile:

Also, I have a handful of LEs in stock to mod that are unspoken for. They are a fair bit easier to acquire now Zebralight is finished transitioning from the original XP-L2 model.

Here’s an interesting option I’ve been wanting to try for a while. This is a dedomed 5000K Samsung LH351D “dog fart” (SPHWHTL3 DA0GF4RTS 6). Nothing fancy, just a razor blade slice without any polishing.

The stock SC64c LE looks pretty decent on H1. I’ve tested quite a few, and they usually sit in the range of Duv 0.0004-0.0008 with CRI ~9070. Lower outputs get increasingly green with slightly higher CRI. Good examples are usually around 0.0033 at L1 (fairly green), while the worst one was 0.0061 (very green).

Djozz’s testing has shown that slicing the LH351D tends to lower CCT and Duv and create a pleasantly rosy tint. The “dog farts” seem to behave a little differently in that they lose a lot of CCT, have more CCT variation, but also end up quite rosy on low modes. In the SC64c, H1 is is a very nice Duv –0.0005 at CRI 9151, and by L1 it’s –0.0031 and CRI 9675. Because the “dog farts” are a higher flux bin, H1 output is about 690 lumens vs. 745 lumens for a stock LE even with the dedoming loss. This isn’t an ultra rosy sw45k, but it has a great tint at any level and maintains most of the stock output. Because it’s a dedomed LED, throw increases from 123m to 165m, the hot spot is smaller, the big blobby corona typical of LH351D is greatly reduced, and the spill is less purple. If a customer desired, I could trim the dome to the edge of the die to increase throw even more at the expense of corona and spill.

I’m interested to know what everyone thinks of this option. Is the SC64c DF something you would like to be able to purchase?

Now I know you didn’t made up the “dog fart” terms. It’s actually the real part number….
All this time I thought it was you :person_facepalming:
Bring it down lower the BBL Bob, shave closer to the phosphor layer :stuck_out_tongue:

Very cool results with the slicing of the Samsung LED.
I have read this LED is fairly floody. How does the sliced version compare to the 219b in terms of beam profile?

It’s similar to the 219B but the edge of the hot spot is more focused. Quite different from the stock LH351D with its blobby corona and larger hot spot. I’m going to take some comparison beamshots tonight to demonstrate better. Unless you really can’t deal with the smaller hot spot, it’s much nicer than the stock LE because the tint is great at every level rather than just H1.

Don’t blame it all on poor Bob. Those degenerates on /r/flashlight are the ones who noticed the DA0GF4RT part# for the 5000K and started giggling about it like middle schoolers.

In the home stretch! I decided I do a better job of finishing everything up when I press them in a big session so these are otherwise finished lights (well, except for the one with the loose driver) just waiting to be pressed and shipped.

Keep up the good work, Bob! :+1:

How many of these have you modded now? Any catastrophic fails along the way?

I use mine every day and am still wowed by the tint.

I was already a fan of Zebralights and 219B sw45k emitters, so this light is definitely in my top three favorites.

If anyone is on the fence about getting one of these, do it!

I’ve done…. maybe 30? A couple dozen for customers, but also a handful of my own personal lights. I have one completely dead light and one that misbehaves, but my success rate has generally been quite high. I’m also using a much more gentle reflow method I’m really happy with now. No takers on the dedomed LH351D yet, but I rather like the one I built for myself. A significant improvement on the regular LE since the tint is awesome on every level, not just turbo. I also recently built a 219B Zebralight H53 which is a neat little light. 165 lumens with an sw45k 219B.

Sometimes it doesn’t quite go as planned. This component was ripped off the bottom of the board because it was encased in excess adhesive used to hold the positive lead in place. Possibly repairable if I’m willing to put hours of effort into it and carefully reflow the entire board on both sides, but obviously not saleable anymore. There’s absolutely no way to avoid this kind of loss.

In more positive news, I shipped some lights today, and more will follow over the next day or two :slight_smile:

Heading to the post office to drop off three lights. If all goes as planned, three more tomorrow! You should receive a shipping notice from PayPal if yours was shipped, but please let me know if it’s missing a tracking number it should have.

Can’t wait for my tracking notification!
Thanks for your hard work :+1:

Can you please send me tracking? My PayPal notification did not have it.

Thank you

I had a family emergency this afternoon and won’t be able to deal with any modding stuff for several days. Please rest assured any outstanding orders are essentially ready to ship, I’ve just been taking some time to understand an issue I was having. I should still be able to reply to PMs if anyone has any concerns.

Mr. Bob_McBob:

So sorry about the family emergency. Hope all works out OK.


Just received my Zebralight mod after it walked through Canada. I just wanted to tell you publicly what a wonderful job you did on a light I’ve always wanted - simply beautiful.

Big thank you for your efforts, expertise, and the kindness you’re showing your fellow flashaholics.


And for anybody on the fence: This is just what you wanted it to be. Looks and acts like factory, and subjectively much brighter than expected. This is a great, professional service he’s offering.

He even includes some perfectly-cut d-c fix, which was appreciated as I often use my EDC for a photo-fill light, but didn’t want to commit to a floody. This emitter produces great skin tones - just a richer, I don’t really want to say pink, mostly more accurate and warmer tone, and if you need to, you can correct it down a little and achieve truly superior results. It’s certainly not magenta-ish like an older digital SLR, just richer. Mine was a 45sk.


Thank you again! And good luck with your family.
