PM sent

I would like 8 4000k sw40 d220 L2 r9080.

Adding group buy option for the Nichia 219c sm4050e 4000k below BBL

Please let me know if you’re interested and how many pieces.
Still awaiting pricing but I suspect it to be around $3 each.

Well, I “need” some of those, too. Put me down for 10, please.

Any chance of sm4550e 4500k instead/also?

I’ll find out. I imagine this would also be a popular option?

I’d be happy with any 4500K bin below BBL :beer:

I’m down for 7x 219C SM4050E & 7x SW45K & 3x SW30

Diference between sm4550e and sm4070e ?

I prefer the 4000K version because it looks so sunlike at night but I would be down with 4500K rosy version also. Any chance you can get the 4070E, because with the reflector or optic on, it will likely bump the duv above the BBL like I’ve seen with the SST-20 FA3/FD2 tints? I think Clemence was selling the 4070E version previously.

^ good point, similarly for 4500K - sm4570e would be preferable.

sm4550e = 4500K 5-step MacAdam ellipse

sm4070e = 4000K 7-step MacAdam ellipse

What’s the appeal of being below the BBL? I know that means it’s rosy, but why intentionally move away from the BBL?

For me I actually like it slightly below BBL since I’m not a fan of the heavily rosy tints. It’s more of a subjective matter but I think for most people, yellow and green (above BBL) is considered ugly so moving in the opposite direction is desirable.

When I edit photos, I find that adding just a slight tint of red usually makes the photo look better. Of course this is also subjective.
I usually just associate that warmer tones as being more pleasing so maybe it’s a psychological effect. Think sunsets vs midday photos in landscape photography for example.

Why not. BBL is a reference and something we get used for long (depending on someone’s age) because of filaments bulbs, but it’s not an absolute requirement.
Most people are so get used to it that deviations from BBL are noticeable but above, on, or below BBL are a matter of preferences.

BTW, The cosmic microwave background frequency spectrum is a perfect black body at 2725 K

I also don’t like overly rosy, but as SKV89 mentioned a reflector usually pushes up the duv so choosing a bin further below the bbl should hopefully balance it out. Either way, any 4500k under BBL is good with me.

What does that mean? lol
The ideal CCT is 2725k?

In for 20 of the Nichia 219c sm4050e 4000k

If you’re willing to sell some of the Yuji 5mm, I’d buy a few. 5600k if you got any.
