I hope nobody minds doubleposting here. I have also posted this in the C01R thread but one of these lights will have a 5mm LED, so it might be interesting here as well.
Barry was so kind to send me a quick whitewall-shot from his smartphone camera.
From left to right...
Sofirn C01 5mm 670nm (prototype)
Sofirn C01R SST20-DR 660nm (prototype)
Sofirn C01R XP-E2 PR 660nm (series version)
Comments based upon some feedback from Barry:
actual perception of deep red color is more intense than indicated here
C01R SST20-DR is quite similar in maximum brightness - although actual brightness may differ but needs to be measured using a lux meter
hotspot beam shape/profile of C01R SST20-DR is yet to be reviewed in detail as any artifacts cannot be assessed on that picture - for now it looks quite similar to XP-E2 PR
production of C01 using the 670nm 5mm emitter may be revoked as the beam shows significant distortions - final decision is not made yet
After using the C01R for a couple of weeks, I understand what many others have mentioned: with completely dark-adjusted eyes, the Low of the C01R is still quite bright. The High seems like it could do some serious damage with fully wide open pupils.
Since Sofirn has committed to another batch of the (relatively) high-powered C01R, I wonder if they’d consider salvaging the 5mm Red as a one-mode sub-lumen light and include a diffuser with each. Then, the beam pattern wouldn’t matter at all - even more so if they can find a pebbled optic, too. With this kind of change the C01 5mm Red and C01R wouldn’t compete with each other for sales, either. The niche here is not as a novelty toy, but seriously targeting the astrophotography groups that want an extremely low light that won’t singe your eyeballs if you accidentally look directly at it.
Our latest product C01, using Sophia lamp beads, 3400K CRI 95+ 5mm LED. We have prepared 5000pcs emitter, expected to arrive at next week , Black, Blue, Orange, Green, Desert Tan each color 1K. In addition, there are 1K red , using 670nm red emitter.
Thank you. We all have been waiting for this a long time.
But the other question: will you sell a portion of these lights without a led?
So people can experiment with a led of their own choice, like a UV-led?
