Yuji BC 5mm LED Stress Test - Graph and Images

Yup.

I used a Nite Ize module reflector for one and a Terra Lux reflector for the other.
The photo was taken from about a foot away from the floor.

Btw:

Stopped the test with about 50% output so there's enough juice to see my way to fresh batteries in a sudden lights out.

Let it rest for an hour...

Back to near full output.
Turned it back off figuring 36 hours was a good point of refference of 100% (or near) with very gradual fading to about 40-50% over the next 21 hours.

the r9 improvement with increasing current matches the ebay leds by my eyes.
we need to get some under your test sensor.
pm me and i will set you up with some.

Test Equipment and yes I did not test like this, I did turn off all the lights and blocked any incident light :

Results: Do note I did try a few LEDs from the batch seeing as the 2700k seemed low but they all provided the same results. 5600k is clearly superior. Also note, the 2700k I posted previously is from ma-tumba's order from last year so it's different.

i am sending staticx57 some ebay leds to test.
it will be interesting to see how they compare to the yuji.
