no. And I do not need it, I just need to test it
Okay, let us know how it is when you get them!
do not worry, all will be fine. I use 660nm (for growing lighting) since 2014, and I see difference by my eyes between 630 and 660nm without spectrometer.
Also I am going to order it from another seller too
I asked Barry from sofirn about making an LT1 “Host” (everything except for LEDs and mcpcb) available but sofirn seems to not accommodate such changes unless they can expect 50-100 orders.
Ask him about information support of this project. I mean first mass sunlike flashlight.
What price will be with shipping inside China if 50pcs LT1 without pcb ?
Do you want any other information besides the price? It might help to know what city you want to receive them at.
My address in China is:
银海路陶界岭小区30栋1单元1楼门面房
P.s. Can you give me his contact? I will @#$% his mind directly =)
Be nice 
WhatsApp: +8615773183209
Is the best place to reach him at
Wee will $%^& his mind together 
He is the boss of the Sofirn?
Because of the risk of spam messages and calls, it is generally not a good idea to share personal contact information on the web. I recommend editing the post to remove the number and sharing such information by private message.
I do not think it matters since it is the number sofirn lists on their website for customer service.
Oh… It’s not interesting! He is not the boss 
Barry was the Sofirn contact for various BLF-Sofirn joint projects, like the Q8 and the LT1 lantern, although he is not the boss, he has influence, and for us the only one there who speaks english.
I’m not sure how is the red LED going to be used here.
Is it meant to fill one channel, so ramping warms the beam up by adding red to the spectrum?
yes. all 18 leds will be red 660nm
about new SOL2835 (3rd generation)
and spectrum of the 3032 leds
It is brighter, but I do not like spectrum
It is not SunLike, it if just “high CRI” ! 
I understand that 660nm is available but I can’t resist to mention an experiment I did a few years ago.
The experiment was adding red light to 80CRI 2700K leds, and it appeared that the most effective wavelength for that was 640nm, which is more efficient than 660nm (almost 3 times as visible to the eye) and makes for a better spectrum with less of a gap in the red region. The CCT went down to about 2400K if I remember well, and CRI went up to 95.
red peak of the SunLike LEDs not in the same place as in cheap leds. So, 660nm will be better. And it is real red, not red-orange.
SOL2835 4000k:
Cheap LEDs 4000k:
I’m not sure if I like the sunlike + red idea…
SOL has no problem with producing 660nm and even over 700nm.
I have a feeling that colour rendering is more likely to go down than up, especially if there’s a lot of red mixed in to the spectrum.
But I’m not sure about it.
Anyway, mixing different red wavelengths might be an option as well.
Idea was make 2200k CCT and etc
Also I think that it is like emergency red light. After red light, eyes adapt very quickly to the darkness. Rest assured, after SunLike LEDs too!
