Update 180118:
———
The VR16S1 and VR16SP4 MCPCBs are the store

Does the VR16SP4 work with the new cree LED’s? I might need to grab one of those so I can test the new Cree LED’s.

clemence · January 17, 2018, 9:07pm

Not a perfect match but should be more than enough due to its excellent thermal properties. I posted the simulated picture of XD16 on VR16SP4 somewhere. With VR16S1 it fits better with full pads coverage

With E21A:

With XD16:

XD16 has bigger pads and wider gaps

(dream) may be 219C sm4070e will be re-stocked… I will buy 3-5 pcs
I have receive and tested 219B sw45k - best universal LED, but for some application of night vision he is slightly “cold”… Wish an 4000-4200 CCT and magenta tint

clemence · January 19, 2018, 12:38pm

I can’t promise, seems it would be harder to get those sm4070e again. Those were only 100 pcs.

ma_tumba · January 19, 2018, 12:44pm

Will be in for some, too.

ＷｏＷ

I have to order again．

I have never seen 6500K R9080！

djozz · January 25, 2018, 9:30am

oh-oh, I’m in the same boat, ordered some. I have not even received the last order of 2000K E21A’s :person_facepalming:

edit: I just tracked my last order (1 month ago) and it is still in Indonesia somewhere (ordernr 10105)

clemence · January 26, 2018, 12:34am

Don’t trust the economy tracking number. It’s not always updated, must be already somewhere in NL.
I’ll check it for you later this afternoon.

I don’t use sunscreen in the workshop. It’s just something (I guess) widely available throughout Asia/Europe/US.

Nice work Clemence. Comparison photo with mixed CCT’s is great!

ma_tumba · January 27, 2018, 7:43am

Hey Clemence! How green are 5+K e21s in real life?

clemence · January 27, 2018, 4:23pm

You know what? I forgot the beamshots! :person_facepalming:

Clemence? Why don’t you deal with Skilhunt and custom made some H03 RC with your bin? Even their throwers are quite nice.

They have easy-modding (and affordable) hosts, you can find easily good drivers for the more demanding, or simply use their own electronics. Add your value to that, and sell some TRUE limited Deluxe Editions (forget AT Sick )

People like me don’t rush after stupid extra lumens, trying to show off that they can throw some greenish light to the moon. There is a real market for what you are doing.
When people get the opportunity to test high quality tints (and you have them), they will never return to low CRI . Especially talking about EDC/headlamps

Work with true outdoor people, not that bunch of potato couch who just know how to show-off online their useless stuff…

(Mine is more powerful than yours Facepalm etc…)

Small quantities, but high quality.

Cheers

Yup agree, now I just can’t stand low CRI anymore. I’ve been extremely picky for CRI and tints ever since.

Personally, AT has the looks and features I like. Efficiency and reliability are it’s biggest issue which I’m trying to fix. Without the latter, it’s by far one of the best at it’s price class. Skillhunt is easier to mod, I agree. But it lacks features and UI AT has.

Thanks for the suggestion, hopefully a manufacturer would able to help us for a special true tint snobs EDC/headlamps product line. I’m not interested in making a group buy of special edition stuff. I prefer a user mod-able EDC that will last for many years ahead while still has the robustness of sealed OEM. And that’s what I’ve been trying. Tried to contact Fenix but got no reply yet.

While I’m just like you, an outdoor guy who knows how 300 lumens high CRI is so much better than 1000 lumens green lantern, I’m also a scientist wannabe :nerd_face: :nerd_face: . I like to tinker and….I do play with unnecessary experiments. Without that idealism, I wouldn’t make those boards anyhow.
I say, let them play and experiments. Because that what makes BLF so fun.

Green? Not at all, unless there’s something wrong with my eyes. Even E21A sm505 D320 R70 (my guinea pig) is one of the best low CRI with just the right amount of slight pink. Jensen567 also confirmed this, he kept his R70 (he supposed to kill them! )
All those E21As are my collection’s best CRI and tints (well, I don’t really like the sw45k)

It is not that I see any green in the pics, my question was related to the color diagrams that you have on your site. It is great that in fact the tint is neutral.

Re the sw45k. Well, I got the 6x of them and installed one into one of my DQG Spies. And then I installed 3 (THREE) pieces of lee filters to get optimum result. These were

- main +1/2 green filter to remove the primary rosy tint

- wide ring made of –1/2 green filter

narrow ring made of ~~1/2 green filter~~ these two remove the green rim, inherent to any nichia LEDs except (domeless) N083B in a mule configuration.
and a DC fix on top of these - to smooth out the radial color variations introduced by the rings

I invented this trick with lee rings when I had to mitigate tint shift in my e1e with Tana’s SingLED light engine. The shallow reflector of the e1e made the color of the hot spot really nasty, for it collected that greenish peripheral part of the original beam.

On the other hand, domed nichias are quite good in triples when their gree periphery does not affect the resulting beam. So 3 best of the remaining 5 will go to some triple. I really appreciate the way these sw45k bring up the reds at low lumen settings

I am really and I mean realy looking forward to getting those domeless E21 LEDs

g_damian · January 27, 2018, 10:41pm

Which combination is your favorite?

clemence · January 27, 2018, 11:18pm

For work I still fav 5600-5700K. Outdoor 3500K. General purpose 5000K
But this new 6500K R9080 is so amazingly clean, whites are brilliant while the rest of the colors pops. Perhaps I can tolerate this one for my office space. Never liked anything above 5700K before.
