XP-L2 V5 Output & Death test by Texas_Ace Over 2200 lumens! Still worked after 15 Amps!

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.

If you use flat white paint, that light is not lost but will be fairly evenly distributed in the spill.

Yeah, my idea with the 219c’s was we would 100% know they were the same bin/tint for both of us and thus be the most accurate comparison.

This light is an even better idea though. I am curious to see what the results are.

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?

Is Tipp-Ex something that is known over where you are?

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

Yes, white-out was what I was talking about, the brand name escaped me.

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’?

I print up my own spacers all the time, I have a choice of colors but I think white will work fine. I just have to make one extra tall.

Ok, I just updated the OP with these updated charts, everyone think these are good?

Looks good!

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.

Who has bought all the XP-L2 5000K from Kaidomain? :cry:
I wanted to buy some too!

Texas_Ace perhaps? :smiley:

lol, wasn’t me, I was not even aware they had any in stock. Although I was not real impressed with the 5000k tint to be honest, it seemed a lot cooler then that so I want to go for 4000k when I order them. I have not been able to find any for sale other then mouser and digikey though and I don’t plan on making an order from them for a little bit.

I have my eyes on the 4000k 80cri 3 step binned versions I see floating around. They are V3 instead of V5 but usually the better CRI is well worth the drop in output for me.
