* Most common bins (SM403, FB4 etc) have been reported to be slightly green
Based on BLF tests, it seems Luminus may be slightly more conservative than Nichia, so the output difference may be smaller than the specs suggest.
(2) There is a noticeable difference side-by-side. Not huge, but I definitely see the difference between the 3000K lights in my kitchen and the 2700K lights in my dining room.
(3) This really is a matter of preference to figure out on your own, but your attempt at balance makes sense
(4) Total Internal Reflection (TIR) optics seem to usually do a better job of smoothing tint out across the beam than reflectors. Reflectors usually produce a more defined hotspot and spill area that I find makes a versatile beam.
(5) As in the table, in many emitters, increasing the current tends to shift the tint to be rosier, but I don’t think this is universal to all emitter families.
(6) A PWM driver will have fairly consistent tint and efficiency within a single power channel. A current controlled driver will experience more tint variation, but should be more efficient at lower outputs.
Just so we don’t get our hopes too high on the 219B 3000K. I bought some NVSL219B-V1 sm303 D200 R9080 from LEDrise.eu and measurements I got in a Convoy S2+ triple on highest output:
CCT: 3372K
DUV: 0.0011
CRI: 95.2
R9: 84.5
Rf: 93
Rg: 102
It is above BBL so noticeably more yellowish than the SST-20 3000K or E21A 3000K. Maybe a lower output D180 would have produced a more rosy tint that we are all after. I’m hoping for the best since I’m on the group buy list but just letting everyone know. I would have more interest in the 2700K since that one is to date untested and might give us a pleasant surprise.
Yep I’m hoping the test results will come back favorable if my order goes through. Just awaiting confirmation right now.
My rep informed me that sw27 is unavailable at this time and there’s no projected ETA if those will be available anytime in the future so the outlook on that is dim. Sorry guys.
As for the 219c sm4050e, I’ve submitted my request and awaiting a response. Will followup by Friday if I still don’t hear anything.
I might also be getting a small batch of sw35 in addition to the sw30 if that comes through.
UPDATE: So in regards to the 219c, right now only the sm403 bin is available. None of the other options are in stock. I’ve requested to be notified in case they ever do become available. I also made a mistake and didn’t realize that the sm4550e and sm4570e bins don’t come in 90+ CRI so they will be dropped out of consideration.
219b sw30 and sw35 are still likely to happen. Will keep you guys posted on those as more info becomes available.
