[GB ended, news update only] Last batch of 219B sw45k R9080 and sw40 R9080

[clemence]

I guess I’ve fixed all those error entries in the sheet. Do you think it’s OK to end the GB by 180530? Or should we extend it by one more week?
600-700pcs of those 219Bs should be enough.

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.

[clemence]

I had a conversation with a friend and there was a thing or two I also want to share here…

Thanks for the good gesture but please use “goods and service” for some reasons:

- It’s against PP policy

- Safer for you (who knows Annunaki would kidnap me one of these days?)

• I already calculated all the duty tax, fees, coffees, handling, etc… for all the items I sell here

Anyone?

Just sent payment for (12) sw45k + $5 shipping.

Thanks for putting this together.

I have no issues with the extension by one more week.

[alifpb98]

Extend the group buy date. I think many people will appreciate it.

[Lyyyyghtey]

Oh, goodness, obsoleted:( I’ll definitely place an order, once I figure it out.

Could I order a 4XP board and have it populated with two each of the SW40 and SW45?

These 219B (and 219C it seems) all tend to have Vf very close to 2.75 @ 350mA. (not that I’ll be using them at that current, I just still test there ever since the Luxeon 1 days!)

That would totally solve any worries about the SW45 being too lavender and the SW40 slightly too yellowish. I’ve noticed both these tints myself. They don’t really bother me but a mixed board would be another very nice option!

Please understand, I am a tint snob.

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

Okay will extend it for another week.

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

Thnx.

I didn’t forget, I just misplaced it next to Galaxywide

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

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

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.

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.

Candlelight is generally about 2000K. Lousy rendition, but soooooooo warm…

[jon_slider]

@Lightbringer

Candlelight is generally about 2000K. Lousy rendition

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

[clemence]

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)
