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.

Hi Azhu, can I also get 10 SW45K? Thanks.

Joshk · August 1, 2019, 6:49pm

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.

Joshk · August 1, 2019, 7:01pm

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

SKV89 · August 1, 2019, 7:14pm

So there is only sw45K but no sw45?

Jon, I actually didn’t know there is a N219b 4500k 9080 SW45 and a N219b 4500k 9080 SW45K. What is the difference? What does the “K” stand for? I couldn’t find any info in the spec sheet.

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.

blacksunshine · August 1, 2019, 7:58pm

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

*UPDATE: CLOSING SALES OF SW45K FOR NOW UNTIL I CONFIRM STOCK. Feel free to still post qty interested and I will follow up with you should there be any left.

*UPDATE: sw40 and sw45k TEST RESULTS ADDED TO OP

Lund1660 · August 2, 2019, 2:26am

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?

BlueSwordM · August 2, 2019, 2:29am

The SW40K will have better red color rendition.

contactcr · August 2, 2019, 2:31am

Wonder what current this was taken at

azhu · August 2, 2019, 4:16am

These were tested at 200mA.

Lund1660 · August 2, 2019, 4:32am

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

SKV89 · August 2, 2019, 4:36am

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.

Joshk · August 2, 2019, 4:39am

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.
