I ordered a 219c triple board and some bare LEDs last night. I'll try to get some comparison shots up when I get something built.

May have missed it, where did you order from?

Does anyone know about any incoming lights with the NVSW219CT? I'm getting pretty excited!

 

[markr6]

Throw this baby in an L11C please!!

 

[recDNA]

So the 219C is brighter than XM-L or XP-G2 with a smaller led? Sounds nice. Should make a decent thrower?

 

[more_vampires]

Oh yeah, got my eyes out. Anyone spotted the first factory light with 219C?

The Mountain's got them, I hear. I was meaning the big factories.

 

[markr6]

I'm usually into the 90+ CRI stuff, but I may settle for the 80 in this case if the 90 never comes to life. Sounds like it may be dead in its tracks based on the previous page :(

But Nichia 219 wasn't always about the high CRI for me; the consistency was another big part of it.

 

[Prepped]

This is a shame to see the current market trend leading Nichia in this direction. I'm looking into getting another custom Vinh light with the highest CRI possible, so it looks like I'll be going with a 219b.

The newer 219B-V1 actually performs better than the old 219B in all areas but yes, if Ra and R9 is what you're after, 219C may not be for you.

So 219b with r9 would be better than the 219c in colour rendition right?.

Depends on the binning for each. The best CRI you can possibly get with the 219C series is 80 (min)/83 (typ) Ra and 0 R9 (min). So if you are happy with that level of color rendition, the 219C is "superior". These are technically capable of D300 flux (max) but D280 is typical.

The 219B-V1 (which came after the 219B) is technically capable of 90 (min)/95 (typ) Ra and 80 R9 (min) with highest flux bin D220. Or, if you drop down to 90 (min)/93 (typ) and 50 R9 (min), flux bin D240

*Sourcing any of these particular bins is another matter all together.;)
