Candlelight is generally about 2000K. Lousy rendition, but soooooooo warm…
thanks for the food for thought
I agree 2000k light, top right @5000k WB, has lousy rendition.
Rendition of a 2000k light improves, bottom right, @3000 WB
I wonder if Candles render more color at night, than during the day 
Although I personally find high CRI in < 3500K doesn’t do much in differentiate between colors, no low CRI < 3500K can mimic campfire/candle light unless they have very high R9 value.
CRI 8000 - 9000 3000K looks like carburizing acetylene flame (deep yellow)
CRI 9050 3000K looks like looks like kerosene storm lantern (orange)
CRI 9080 2000K looks like wood fire/candle/match (almost amber)

….And it takes almost an hour for my eyes to adapt between high contrast CCTs (example: 5700K daylight to 3000K lit room).

Now I’m more confoozed than ever…
I might be late to the game, but do you have many left?
I already got a bunch of 93CRI 4500Ks, but I was toying with the idea of playing with some 9080s. And with the pink vs violet issue, I have no idea what to get.
So… would you have, say, 10 of the 4500Ks and 20 of the 4000Ks? That should last me a while if not a lifetime, what with the 93CRIs, and bevy of LH351s, too.
I know I gotta stop this, but in the meantime… :weary:
Oh, and how much would Int’l EMS be to the ’States? I’d be okay with the 5buk option, but if EMS is, shall we say, Significantly Faster, I’d spring for that.
Thanks!
Awesome info, thank you!
Is the video a 2000k E21A 9080? Love the candle colored LED
google agrees with your comment that dark adapted vision shows fewer colors, and they think it takes at least 20-30 minutes to dark adapt after sunlight…

Scenario question, choice of CCT for movie flashlight… when we go into a movie theater during the day it is hard to see which seats are empty.
Would a 2000k light or a 5000k light work better for Me to see the seats?
Would the people in the theater hate me less for blinding them with my flashlight, if it was 2000k or 5000k LED?
Better for me, may not be better for them…
both
the 4500k is “better” when you are adapted to daylight
the 4000k is “better” when you are adapted to incandescent light
You can get as much LED as you want as long there are stock in the warehouse. I haven’t order any of these LEDs yet until next week (180604) when the GB ends.
EMS ID to US up to 50gr is USD18, delivery time 4 - 10 days. My latest shipment with EMS was to member Pavlo, reached US in 3 days.

Yeah, when dark-adapted, you’re using your rods (scotopic vision) vs cones (photopic vision), and rods only register intensity, not color.
That’s when you doubleclick your Q8 to find your seats…
Correct, E21A D160 sm203 R9050. Its rated at 9050 not 9080, but Maukka test showed it’s 9598. Expect variation between reels…

with what CCT LED?
Like!
want
get
Ah, okay. Thought you had X of the 4500s and Y of the 4000s, and once done, they’re done.
Okay, so 20 and 10 sounds good. And being that I probably won’t even be ready to use them for a while, the 5buk option sounds fine.
So… PM to work out the details? 
Who cares? Everybody’s just gonna be seeing big green blobs in front of ’em afterwards. :smiling_imp:
Update 180528: Table updated for simpler viewing.

Payment Sent for 6 x sw40 + $5 international shipping
Thanks!
Oh, dear, that’s 9598? I had been hesitating ordering any due to holding out for higher R9. (I missed when Yuji used to have something similar). Now I won’t be able to do that any longer! How exciting!!! I MUST have high-R9 candle-CCT LEDs!!!
I would like please:
10 of the SW45K (these are entirely consumed in populating the MCPCBs I ordered in the store)
and:
15 of the SW40. (9) used on the MCPCBs and 6 sent as bare emitters.
PayPal sent for $65. The last $5 comes from the extra shipping charge I’ve already paid due to placing 2 separate store orders, with all 3 orders shipping together. I hope this isn’t too confusing. Thank you again!
I’d like to order 3 × SW45K reflowed on Noctigon XP16 MCPCBs, please:
3 × SW45K at $2.80 = $8.40
3 × Noctigon XP16 at $1.85 = $5.55
3 × LED reflow service at $0.50 = $1.50
plus shipping at $5.00
Total: $20.45
PayPal sent, and thank you for doing this!
