WTS/GB: NICHIA 219B NVSL219BT-V1 R9080 EMITTERS! sw45k, sw40, sw35, sw30

those duv shots are outstanding!

now I know why I felt my sw40 9080 needed a lee 1/8 minus green

azhu, just curious what did you end up getting to be able to measure this?

I’ve never tried the minus green filters. Are you cheap to order?

.

I figured out how to use my i1DisplayPro to measure the CCT and Duv values.

Ah cool, wasn’t sure if it would give you Duv so that’s good to hear. So you only cannot calculate CRI then I suppose.

Yeah I don’t know CRI and the specific R values. I’ll need a spectro for that.
At least I know the exact CCT and Duv values for my emitters and lights now.
The test also shows the lux it was recorded at so that’s pretty cool.

Thanks for sharing your data! And for the beamshots of numerous different emitters in the same host! Those are both highly appreciated information.

I see also the reference line your system draws has a dogleg at 5000K, where the typical reference changes from the black body locus to the daylight standard illuminants.

That’s not a big deal, especially since all these emitters are less than 5000K. However, if the reference used can’t be adjusted, then when showing data for emitters at or above 5000K, it will need to be kept in mind. As can be seen in the charts, the difference is somewhere around 0.0025 DUV.

Sweet! Another BLF member with the ability to take photometric measurements! I find DUV measuring more useful than CRI because usually LED manufacturers are pretty honest about the CRI rating but DUV is harder to guess. CCT and DUV combo is what I mainly look for in the test data.

Btw, the batch of sw40 that Clemence sold in his GB last year was very rosy. I wonder if that was the sw40k or if sw40k even exist.

the BBL is misleading without the other info anyways cause the scale of the plot changes. I would suggest he also put the actual CCT since the average person knows what that means and then you have everything you need to get x,y and plot it yourself with Osram Color Calculator, ex:

Input CCT and Duv to get x,y:

Input x,y (multiple if you wish):

yes
I sending you my notes and links to LEE filters, by PM

Retested the SST-20 tonight. So did I not get the FA3 bin? All the points do look like it would be under the FB4 or FC1 bin…

Probably not. You are testing the worst combo though. Low power, smo reflector and AR lens.

I bet if you remove lens and use a 14500 it will be less bad ( but still not FA3 )

All just a guess though since there’s only limited data for FA3

You may want to consider getting like a $5-15 adjustable buck power supply and cutting up an old DC power supply. This way you can test with a known current and easily drop other optics on top.

I use this: ICStation DC-DC Adjustable Buck Converter 5.3V-32V to 1.2V-32V 12A Voltage Regulator Step Down Module LCD Digital Voltmeter Ammeter with Shell https://www.amazon.com/dp/B07KYJ4L48/

I actually recently got a DC Power supply. Haven’t tested it out yet.
I also just remembered the lights were all tested with dc fix on. I bet that had something to do with it.

The SST-20 I tested was from a J4 flux bin. I also have J5 flux bin that I will test tomorrow probably.

I tested these emitters on my spectrometer at 4 different power levels. Check it out here

Torturing that poor 219B

Just received mine, flawless condition. Many thanks azhu!

UPDATE: I have sw30 and sw35 in stock again.

Great. May i have 4x sw35 please?

Of course! pm inbound.
