Man, that “small amount of the 4500k” seems popular.

Put me down for (5) 4500k sw45k d200 L2 r9080.

That should satisfy my FOMO and curiosity. Smile

If I recall you were expecting test results to be delivered yesterday. What’s the latest news?

So there is only sw45K but no sw45?

If my understanding is correct, the sw45k is under the BBL (more rosy) than the sw45. The sw45 could be under the BBL as well but the sw45k is guaranteed to be under so you know for sure that bin is usually rosy. I’ve had a batch of sw45 that was slightly rosy but overall, it’s more neutral white than the sw45k.

Oh that’s very interesting. Is the suffix “K” added by BLF folks to indicate below BBL color bins because I can’t find that in Nichia specs?


The Suffix is actually used by Nichia. You can find it on the data sheet. Not sure if they discontinued the sw45 prior to this though.

PM sent. I actually think I’m about to run out. Need to check stock when I get home.

Buddy wasn’t feeling well and wasn’t able to get around to it. Perhaps by tonight. I’ll update the OP as soon as I have results.

There WAS sw45 as well as sw45k. I’ve not been able to get a hold of the sw45 for a while now so I don’t know if Nichia discontinued that and only went with sw45k.

If there is any sw45k left, I’ll take 5.

So it looks like the the sw45k has a lower r9 value than the sw40k. What does that mean and which led has the better results?

The SW40K will have better red color rendition.

These were tested at 200mA.

So according to the test results would the sw40k be the better overall performer maybe just a little dimmer?

I wonder why the test result does not show the DUV value. The SW45K seems super rosy according to the graph and the SW40 seems rosy too. Considering it is tested at only 0.2A, at 1A or above, the SW40 should be the better looking tint since the SW45K might be too rosy.

I seriously appreciate the testing, thanks for doing it.
But I too am wondering if 0.2A data is relevant to the power levels we want to run through them.

On paper, yes I would agree that the sw40 should be better in this case.

200mA is on the lower end so we can expect the CRI to drop a bit when more current is used. Still these emitters should prove themselves to be very nice. I plan on swapping some of them into my lights this weekend to see how they perform. Will post beam/tint shots when available. Stay tuned!

And DUV drops as current increases meaning it gets rosier

Updated the OP with DUV data. Thanks for reminding me.

sw40 DUV: -0.0031

sw45k DUV: -0.0044

This will certainly appease the ever growing pink crowd. Not my preference but i’m the minority. If the lower CCT ones end up closer to BBL i’d get a few

Shows tint. If it’s positive it’s above Black Body Locus (green). If it’s negative it’s pink.

Here’s a random website’s graphic, the line in the middle is “0.0 Duv”

But the lower your CCT is the more the “green side” looks yellow. Same when you go to the extreme other end. More blue mixed shades

the k means nice and rosy! its my favorite
the no k is still a little bit rosy

here is the rundown in pictures.. (one page back)

Maybe it would be worth deep diving into Color Temp and Tint.

On average we expect an SW45k to be more rosy than an SW45

I think that is an error
I believe this is more accurate

both the sw40 and sw45k have great red rendering, the 45 CCT is cooler white, and its tint is pinker

Can someone tell me how to differentiate the cathode and anode sections? I also having trouble finding a data sheet anyone have a link. Thanks so much.

I usually place the LED with the cathode mark (triangle) on the upper right like so: [+] [ ] [-]

But following diagram shows the cathode on the left side, hence the triangle on the bottom left. Hope this helps.

Not the most scientific but here’s a general comparison of what the sw40 from this bin looks like:

The 219c 4000k looks rosier than the sw40 and sw45 in that comparison. That sw45 is not a sw45k correct?

Also is that 219c 4000k the stock emitters that comes with the FW3A? Surprised how nice it looks considering all the the 4000K 219c I’ve seen in the past are greenish.

Yep that’s the 219c in my FW3A. I was also surprised at the quality of these 219c since most of my other 219c are usually more on the yellow/greenish side. Also you are correct, the sw45 isn’t the k variant but it does have some rosiness to it. This was just a quick photo from my DSLR at a custom white balance of 5000k. Results from the camera are never as accurate as how people see these emitters with their own eyes.
