Tint on the new 144AM 4500K looks pretty good!

4500K is the sweet spot for most people yet the hardest to get it right.
219C isn’t available in sm45x 9050, let alone 9080. 219B has the sw45k but isn’t very powerful and too rosy for some people. 144A is the sweet spot between power vs. package but it’s the least appealing in terms of design.

And all those high 90+ CRI Nichias also require specialized optics to mix the tint evenly. Somehow finer phosphors seems harder to mix/make. High CRI LEDs aren’t match for clean throwy optics/reflectors, at least for now. Some tint mixing either using simple diffuser or criss cross rays routing is needed.

I got excellent result with minimal lumen loss using plain Luminit LSD, the efficiency can be further improved by 14% with special request for AR coating on both sides of the LSD. Simple frosted diffusers common in flashlights didn’t do very well.
Using uncoated 5 degree plain Luminit’s LSD I got - 0,3 exposure in most tests.

Colors get prettier on LSD… :disappointed:

What does LSD mean?
Is it diffuser film?

Ah, everyone needs a pair of rose colored glasses.

I’d like those glasses as well. 219B-V1 D220 R9080 sw40/sw45k would mean about 92% of light output compared to the 219C R9050 D240 if you don’t go past 1.5A per LED, but with even better color reproduction…

Pink glasses, LSD and some 219B-V1 4000K R9080…
Life will look sweet indeed… :nerd_face:

Seriously though,
couldn’t you just ‘depolish’ a TIR to get some diffusing and eliminate the losses of the transitions from TIR to diffuser (and the air in between them)?
…provided you get a nice depolishing job done of course…
I guess sandpaper leaves too sharp scratches that will just eat up the light, but iḿ not sure…

But you’ll get no control over beam angle. It will become a “full” diffusion. With LSD you have precise 1, 5, 10, 30, 60, 80 degree diffusion options. They also oval have diffusers too. And you can combine them even within the same single TIR/reflector (stacked, cut, shaped).

My 219C 9050 sm403 from djozz arrived today. But you forgot the silicon gaskets for the S2+ :cry: .
Can you please send me a price for 4 gaskets + 3 MCPCB´s for the 144a + standart shipping.
Thanks in advance!

Yes, I forgot the gaskets, sorry about that, but I can put then in an envelope for you today. So you like 3 of my N119 boards with them? Mind that you will have to scrape away some solder mask to make the 144A fit. Make it $6 for the boards, that’s all :slight_smile:

Well, you can polish it again afterwards with a felt drum and maybe some polishing agent.
Bead blasting would be good too, but takes special equipment (that i don’t have)
And how about spraying a mist (tiny droplets basically) of clear coat on it?
…i guess i’ll have to try it myself…

Are those the translucent membranes that go under the metal button of the colored S2+ ?
(I could use some too.)

Yes, still have quite a stash of them. Mind that the effect is pretty cool but you need very bright tail leds to notice the light (almost all light is lost under the metal cover). A lighted tail with a normal translucent silicon cover is way brighter and more efficient.

I’ll PM you.

All Possible but when you had done hundreds of light fixture you will want the luxury and ease of use of this Luminit LSD :wink:
Their DTF [Direction Turning Film] was the first product that led me to them. I’ll post the beamshots of all the Luminit LSD samples I have.

Back on track:
Did clemence succeeded in sending the next LED package to djozz on dec.26 ?

Clemence received the LED’s on the 26th, me and Djozz both sent payment for our group buys today (had a few late comers and clemence wanted to be sure and test the LED’s for the egg yolk issue first, which he did yesterday).

Clemence is going to ship them to us tomorrow. So hopefully they show up early January.

Thanks Texas, tomorrow it is, then.
Keeping my stove hot, to reflow them :partying_face:
