Sofirn C01R deep red [sold out, discontinued]

Big, if true. Is that claim originating from a trusted and reliable source?

Djozz + Barkuti,

I just asked Sofirn to try testing BOTH tints as soon as they come to make a prototype. They will now think about the idea buying some XP-E2 deep red and XP-G3 deep red but nothing is for sure right now. They told me they have very few influence on the exact flux bin, though. Until now I guess they have XP-E2 red on stock, only.

I also asked for a C01S with SST-20 2.700K 95CRI but they got another idea, trying out LH351D 2.700K 90CRI that is being used in the LT1 also. Maybe they can also try using different host materials like brass, copper or even titanium. But this should be discussed in the general Sofirn development thread to not derail this interest check. ;-)

2200K E21A has a R9 value of 53 and CRI 91 while the 2000K E21A has R9:89 and CRI:96.
Therefore I don’t see why one would chose the 2200K over the 2000K.

Wine red looks gorgeous. Light red anodisation looks cheapish.

Sofirn told me they have difficulties to get Nichia LEDs but Luminus SST-20 is far easier. Anyway, this topic will (hopefully) soon be conducted in another interest check. ;-)

interested!

Interested in 1 more for a total of 2.

Thanks!

Up my interest to 2

For some reason took a look at Samsung 3535 leds section. They market an LH351H Deep Red (SPHRD1L3DH00A4R2D2 Octopart search) and an LH351H Deep Red V2 (SPHRD2L3DH20E7W410 Octopart search, no hits).

The LH351H may be worth testing against their Cree counterparts.

That’s pretty much what I look for in flashlights too.

Sorry to hear that some of your lights were lost in shipping. The C01 is an amazing little flashlight. It’s bright enough for small tasks, makes an excellent reading light, and lasts a wonderfully long time. If they made more of those in that deliciously warm tint, I’d buy ten!

That said, put me down for at least one of the red ones here. Do we know if they will be low-high?

I have test numbers in my scratchbook for 625nm XP-E2, 630nm 219B, 660nm XP-G3 and 617nm Osram KR CSLNM1.23-8K8L-24 . Will enter them in Excel at some point and make a nice post. The Samsung led may be for a next test run.

My general impression is that the performance of red leds from the different leading manufacturers are not that far apart, but that the far red XP-G3 is ahead (but has a bigger die).

VERY Interested in 2 of them

Interested in two units, preferably wine red anodization with deep red LED (660 nm).

Interested in 1

Interested, please put me on the list for one.

Also looked at Luminus' horticulture stuff. Their SST-10-DR is available in both 90° and 130° beam angles. I'm no expert in optics and don't really know how would this impact the beam profile, but the tighter beam angle emitters may be desirable and the perceived brightness would be higher thanks to a more throwy beam collimation (related SST10-DR-B90 Octopart search). Some SST10-DR-B90-K660 parts in stock at Mouser (Octopart search link here).

Concerning the XP-G3 thing, will it fit under the C01S TIR? Because no way if it doesn't, I think.

2 for me

I have highly recommended to use mode oder LOW => HIGH. As far as I know they agree to it as most people seem to like this mode order (see BLF no ano' edition).

Interested in 1.

Tack mortuus! :-)
