I was hoping at some point we could test the same emitter (perhaps the 219c’s we are getting from the same reel) but this would be even better. At the very least I could apply a multiplier to the emitter tests so that my test would be comparable to your back log of tests.
I see some PM’s I am guessing you are one of them, I will read them in a min.
The phosphor layer could be the cause as well, it is really hard to say since the phosphor change happened at the same time as the die flip.
Although it appears everyone is going to this new style, the nichia 319 looks interesting because it might have the high output without the tint shift.
I really have some hopes for the 319A, not that it will beat the XP-L(2) in output but that it will produce very pretty beams, also under Carclo optics.
I’m considering painting the deep part of the reflector matte white sometimes, so that it will mix with the spill.
Or just use a matte white spacer gasket with a high collar.
Not sure yet…
Anyone tried slicing the dome on a G3? Does it improve things at all?
Paining the lower part of the reflector is an interesting idea. I have a ton of spare S2+ Reflectors from swapping in TIR’s lenses, I might try that if I can come up with a paint to use and a way to apply it.
The light has a 4000K 80CRI (Samsung LH351B) led which strictly spoken just gives a correct comparison for that that specific spectrum (can be translated as: colour temp/CRI) and does not see possible differences in wavelength sensitivity for our set-ups (which is dependent on the quality of the reflecting inner surface of the measuring device and on how correct the wavelength sensitivity of the luxmeter follows the agreed Vlambda curve). In other words, a cool white led and a very warm white led may have a somewhat different multiplier between us than the 4000K 80CRI led that we calibrate at.
Yeah, it should also scatter it into the main beam and could improve the main bean tint as well if it is a very matt finish. The issue is how to get a pure white, flat matte, paint that can be easily applied with precision.
Maybe a markout market for “erasing pen ink”? Any good ideas?
I believe it’s called “white out”
It’s very good for this purpose because little light penetrates it, but is reflected.
Iḿ only worried about how good it will stick to reflector surface and without cracking (crackling?) over time
Maybe ‘monodek’ latex wall paint is better
Or it just hit me, what if I made an extra tall centering ring that covered the base of the dome, I could even make it too tall and sand it down as needed. Could this work basically the same? It would reduce total output more then painting the reflector obviously but would be a heck of a lot easier.
That’s what i meant with ‘high collar spacer gasket’.
But how to get the nylon or plastic not translucent and matte / flat?
Or is that ‘splitting hairs’?
Here is a thread on the PVC sphere for those interested, like I said it is really not all that different then a normal PVC setup, but the little things can make all the difference.
