True Color Rendition (TCR)..........

I think Whacky presented nothing to argue about :slight_smile: . He had an idea, told us about it, and defended it. I find it ad hoc useless, but want to see where this thread is going. E.g., there are lots of interesting posts [from others :smiling_imp: ].

:wink:

Aren’t ya hittin’ the Jager kinda late even for U? :laughing: :open_mouth:

Oh, I can be the BLF idiot without alcohol (actually I’m abstinent).

You like Jägermeister?

Hell no. That sheeeeiiiiiiitttttt is too dangerous. :open_mouth: :beer: (only)

I think it stays in yer system so long that a year later you can get a DUI. :laughing:

PS. BTW watts the TCR on that mini whatever yer holdin’ in your hand? Is it a dedomed Mini3?

At least ;).

You mean the TrustFire L1? Scroll down to the last posting and … read :smiley:

Ya know ya got a knack fer gettin me to buy things ya like. I like the looks of this mainly cuz of the button.

Just to humor me before I spring out the $$$$ cood ya give me a TCR on it? :laughing: :laughing: :laughing: :laughing: :open_mouth:

Same LED in the Minis and the L1. You gave it a 5, I’ll give it a CRI 75 and an angry blue.

Watt? C’mon man don’t give me a Rommel Panzer retreat from a Patton deal here. :laughing: :open_mouth:

TCR it for me.

Take the most familiar object you likely know typically in yer right hand; go out in the sunlight prolly tomorrow if today is too late. Note the colors. Then compare them to the flash rendition.

Do the pinks and purples for example compare favorably/unfavorably? That’s the TCR rating.

7.5

What a coincidence that it’s CRI 75! :smiley:

Seriously, after my eyes did their balancing trick, the colors look ok. Like CRI 75 TCR 7.5

It’s still angry blue in the center (8000K+), has a yellow corona just below 5000K and spill around 6000K. Your TCR won’t tell you this.

No butt the TCR succinctly and quickly did without going into your other details.

I now know that this flash with a TCR 7.5 prolly ain’t gonna cut it for me. Butt your’s is just one TCR opinion. I’d like to hear others. Consensus is better. Cuz ya know every flash is different.

Ok. Maybe I’ll get it anyway cuz yer German and Blaupunkt is proof that specs don’t mean everything. :laughing: :open_mouth:

PS. Same thing goes for Pukas, ooops I mean Lucas. :open_mouth:

Don’t. It’s got exactly the same LED/optics like your Mini2 has. You gain nothing except that button and AAA compatibility.

But if you know how to mod it to a shaved SST-20, you’ll give it a 10.

Well ya know how much I like the Mini2’s general construction - that spectacular spill particularly.

Can ya change the optics? Maybe one with a built-in higher CRI? :laughing: :+1: :beer:

All it takes is a 10mm MCPCB w/ SST-20, and you need to extend the wires some mm. The shaved LED fits under the optics.

Beautiful. Thanx. :+1: :beer:

You’re welcome. Enjoy modding.

tint perception changes when the reference white balance changes

the blue and pink beams on the right side of the photos,
are from the exact same light, at different times of day

I give the sw45k a subjective personal preference score (TCR) of 10 during the day and 3 at night.

.

I have learned that the sw45k has a very high R9 CRI score, so I seek LEDs with similarly high R9 CRI scores (the red bar in the next images). The SST-20 also has high R9 CRI (above 80).

The sw45k has a very negative DUV score –0.0055.
I perceive this as Pink Tint, mainly when using daylight white as the reference

The SST-20 scores positive DUV of 0.0034, which to my eye is rather greenish, especially when observed from an incandescent white balance as a reference. I am not a fan of that LED’s Tint, despite the high R9 CRI spec…

I give the SST-20 4000k a subjective personal preference score (TCR) of 5 during the day and 0 at night.

Actually, it has a slight positive Duv, ie, is slightly greenish.

I wish it were that easy.

I got 3 thermometers (clock/thermometer, clock/thermometer/hygrometer, thermometer/hygrometer), and despite being within inches of each other, always have a consistent 5°F spread.

So I have no idea other than relatively what the true temperature is.

Bought a “precision” glass candy thermometer (long-ass ones at least 1’ long), tried a stable water/ice mixture and boiling water, and even that seemed “off” by 1 grad each.

Same applies with voltmeters, lumenometers, etc. Unless they’re NIST traceable, they’re just educated guesses.

Just curious. How consistent do ya find yer rectal ones? :open_mouth:

Within one or two digrees? In any case you should prolly just assverage them.

PS. I just thot I’d ask cuz ya sound pretty anal about thermometers. :laughing: :+1: :beer:

Good catch, that’s what I meant (hence the interesting contrast with the lighting most people prefer) but I’m dumb and said the opposite!
