Comment made on # 28 of sheet.
1x jetusolis ultra high cri @ 5000K.

Thanks.

I’ve never bought a flashlight this way and I’m curious. Does this mean we can get what is essentially a new flashlight with our choice of LED and color temperature? (I’m curious about the Optisolis but I’m not sure if I’d want 3000, 4000, or 5000K.) How much would one of these cost in total and how exactly do we set it up?

I’ve bought a jetusolis 6500K and a 5000K in a heartbeat without checking maukka’s tests.

It appears that the 5000K has natively a bit better blue rendition and the 6500K better red rendition from the tests but, probably because of the LED tint’s influence, by eyes colors with red (red, brown, orange) are popping more with the 5000K than with the 6500K, and the blue shades looks richer with the 6500K than with the 5000K.
The 6500K has a tendancy to flatten the illuminated scene more than the 5000K but shapes of blue objects with the 6500K seems more 3D despite that it has natively less blue colors rendition, maybe again because of the blue tint of the LED that is enhancing blue colors.
Round copper objects look rounder with the 5000K which has lower red colors rendition/fidelity than the 6500K.
The blue anodized Jaxman E2 looks rounder with deep blue shades with the 6500K while it is a bit greyed out and flattened with the 5000K.

It sounds a bit akward.

Generally people are reporting that high CRI has a 3D effect, but both jetusolis are very high CRI and it’s the cooler one that globally flatten a scene with very different colors.
I wish I could test this with a room full of objects with red and adjoining colors and another one with blue and adjoining colors.

There is probably metamerism involved into this due to tint’s LED or spectral composition of its emitted light. I would wish to hear maukka’s opinion about it as he has probably more colorimetric knowledges than me.

@DaveTheDude: which one? Jetusolis or JetuE21A?

The CRI pits the emitter against an ‘ideal’ radiant of its same color temperature. So a 6500k’s CRI numbers will be compared against another 6500k source, and a 5000k’s CRI numbers will be compared against a 5000k source. Since 5000k is a warmer spectral balance, it will have more red, and 6500k have more blue. So just because the 6500k shows more R9 doesn’t mean it actually has more R9 than a 5000k.

@twisted raven
Yes, I understood my “mistake” this week-end while seeing this :
(source)

A quad optisolis with 2x 6500K and 2x 5000K will be part of my next order.

malkoff_junkie · April 16, 2019, 8:09pm

could a quad optosolis be useable in say a Viking Pro flashlight? or stick to E21A 6500k?.
was also thinking of mixing 6500 and 5000k E21A or Optosolis.

Tactical Use.
Thanks.

clemence · April 16, 2019, 8:49pm

No, you can’t reliably use Optisolis in flashlights such as Viking Pro. I can’t give you answer to E21A quadtrix in Viking Pro too, I’ve told you I haven’t done a thorough test about it. Still don’t have convenient time for it.

Clemence, can I still modify my order (not payed yet)? I signed for E21A 3000K complete built. I would like also 5000K JetuE21A R9080 [Kit only: US$4/pc]. $44 in total.

Sure no problem
