Extend it. I know a lot of people still want the 219B before it goes out of existence until the 219C R9080 finally comes to market.

Anyone?


Yes, please keep it open. I’ll be placing an order soon. Thanks

Clemence, can you add “+4pc soldered to 1pc noctigon 4xp” in the sheet. This was the separate PayPal payment we talked about.

Thnx.

I have some of the 9080 sw45k’s and love them. How do they compare to the sw40’s? What’s the difference?

I have both
I like the SW 40 9080 better, though it is slightly yellower than my picky self wants
I find the SW 45 way too pink, and unexpectedly, also way too violet

here is a comparison photo
its not a perfect example, but, it shows the violet of the sw45

shining on the palm of my hand, the sw45 is ridiculously too pink compared to the sw40. again not a perfect example, but you get some idea:

My solution to which is better, is to get both and then decide. I find I usually choose not to use the sw45, and mostly choose the sw40. The exception where I choose the sw45 first, is during the day, when the environment is brighter. But now that I know the violet cast is there, I notice it all the time.

I know a lot of people think the sw45 is the ultimate, and for the selection they have, it probably is. But imho, the SW40 is “better”

when in doubt, definitely get both Smile

one more, this one shows the sw45, w a sw40 9050 and sm40 9050.. but the 4000k units are representative of the sw40 9080 compared to the sw45 9080, relatively speaking


Thanks for the detailed comparison. You convinced me to place an order for some sw40’s. I still have some sw45’s.

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 Smile

Im super grateful to Clemence for making the 219b 9080 experience possible for me.

Happy CRI

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.

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.

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 Smile

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).

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… Tired

 

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.. Smile

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.

Correct, E21A D160 sm203 R9050. Its rated at 9050 not 9080, but Maukka test showed it’s 9598. Expect variation between reels…

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? Big Smile

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!

3 × LED reflow service at $0.50 = $1.50

I may have to bite this bullet a bit… 

 

Sign me up for 4x SW40s and 4x SW45s, which is 8 × $2.80 = $22.40 + $5 S&H = $27.40 grand total.

Payment to virence.cle@gmail.com for an item or a service, doesn't it?  Any further details?

Thank you Smile in advance.

 

Cheers Party
