congrats on another 9080 CCT option… hard to go wrong with more great choices
I think Im biased to SW40’s warmer CCT because most of my use is indoors at 0.2 to 50 lumens, and my house lights are 3000k incan
For higher lumen levels that are used for longer range, the SW 45 is probably a better match for the application, especially when ambient light is around 5000k
I also like CCT as low as 3000k, when in full darkness and at 5 lumens or less… Clemences E21A 2000k are on my interest list as well.
A Selection of Different LEDs is good to have for different applications and times of day
Im super grateful to Clemence for making the 219b 9080 experience possible for me.
Yes I agree. At night, warmer tints are more pleasing. One possible reason for this, at high noon the sun is more blue, but gets warmer as it goes down, leaving our sight more calibrated to the warmer side of the spectrum.
I wonder what the CCT of a campfire is, probably between 2 and 3k.
Thanks!
That is the best and shortest explanation I have ever heard to address differences in CCT preferences.
Makes total sense, as ambient white balance gets warmer and less bright, flashlight CCT preference also gets warmer and less bright.
I think there is also more green during sunlight. I dont notice the green tint of some of my cooler lights during the day. The green gets more obvious after dark, when my brains CCT balance is warmer.
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)
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.
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.
