You can usually detect flicker by looking at the light source with a digital camera  phone or otherwise.
Testing the Rossi Ecat SKLed  Technical Discussions Only

Two light source comparison whether by meter or eye will not compare power accurately if the spectral luminosity varies between the two, unless you have a perfectly calibrated multifrequency optical power meter...

Which is what the official testing method does.
So I wouldn't compare an incandescent bulb to an LED.
Comparing two LEDs might work, since neither is going to generate much outside the optical bandwidth.
I do have a coupla/few 3band (RGB) detectors .. aka Digital Cameras.And an optical bench with a couple of prisms.
Good enough to compare a 10,000 lumen LED (COP 10) to a 1,000 (COP 1)? 
Note:
Dear Dr. Rossi,
Has the certification body confirmed the luminous efficacy stated in the specifications of the SKLed?
Best regards,

I am not anticipating this information,

Reminder : just noting that here. Discussion of what/why/which in the comments thread, please.

On a correct interpretation of the spec there is a factor of 15, and what you have is easily enough.


Calle H is starting to do experiments on lighttoheat detection (presently with a halogen lamp).
https://ecatworld.com/2021/11…ingcopofskledcalleh/He's using a metal bowl painted black, with one thermocouple over the lighted area (48.9C) and one in the dark (34.2C)
Fig. 3 shows a trial run with the dummy. Temperature 1 > Temperature 2 > ambient temperature indicate that the photon energy is well collected by the black inner surface of the bowl and transferred to the bowl outer face. After running for 30 minutes temperatures have stabilized by convective airflow cooling the bowl surface. 
I agree that an accurate measure of performance isnt trivial but if his light is reasonably white it will be very obvious if his claims are even remotely accurate. Commercial 4W LEDs are achieving around 450L and he's claiming 10,000L.

He will have a hard time with his product (?) vs the common 10000 Lumen established competition (tons of companies...) anyway...
Not sure if his design can provide proof of water proof, dust proof, fog resistant, etc. (for the heavily discussed industrial applications like green houses etc.

I think the multiled format would be hard to compare.
Need a beam angle of 60 degrees.

Recall:
Dr Rossi:
1 Lux = 1 Lumen/square meter. If the same luminous flux is focused on 1 square centimeter, how many Lumens do we obtain ?
CC
CC:
10000 Lumens, since 1 m^2 = 10000 cm^2
Warm Regards,
A.R.
…So 10000 lumens may only be 1 lux, but will (un)focussed a bit wider than 1 cm, is how I read that. 

The Lumen rating of a lamp is the total amount of light produced. So focusing it would not make any difference to its rating in Lumens. The same amount of light is emitted its just spread over a different area.
Lux is like the density of light. The amount of Lumens per square meter. If you focus a beam into a smaller spot you increase the Lux but the lamp is still emitting the same Lumens.

Right but 1 lux is basically the same as illumination from a normal candle 1 m away onto a m^{2 }plate, (which would require 10000 lumens, with one lumen each landing on each cm^{2} as Rossisays)
So the candle (nearly hemispherically) has better output than (est) about 53000 lumens (5 sides of a 1 m cube and a bit for the bottom where the candlestick obscures).

Looks like the same (or very similar) chip.

I wonder if Rossi has a heat sink, or a fan?

There is no fan, and the heat sink would be small.

If a candle is 1 lux or 1 lumen per steradian (roughly 1 square meter at 1 meter distance), then the total lumen output should be around 4 pi lumens. There are 4*pi steradians in a spherical area of illumination. So this is about 12.56 lumens.

The problem is relying at all on Rossi measurements. In the recent past he has mangled Kirchoff’s circuit law enough to get 23 OoM electrical
measurementcalculation errors (really anywhere he felt like), and then topped it up by turning a short wave spectral peak into a blackbody (then discounted 10% to be conservative) for a classy 22000 COP for the (obsolete) progenitor of the SKled.
In fact Rossi is wrong above (on the high side of course) by, what, 5 orders of magnitude, which is quite high (even for him) on a oneshot soliloquy of his abilities. 
I'd suggest that Rossi's conversion is correct, it's perhaps just a matter of interpreting what is being said.

With Rossi that is always the case, more than the usual.
However 1 lux = 0.000001 lumen/cm^{2}.
………… 1 lux = 1.000000 lumen/m^{2}
So if all the lumens fall on 1 cm, instead of 1 m^{2}, there will be 1 lumen on that square cm not 10000.

Actually I think 1 lux = .0001 lumens/cm^2. Note there are 10000 cm^2 in 1 square meter (because 100 centimeters = 1 meter, and 100 x 100 = 10000).
Therefore 1 lumen falling on a square centimeter is 10000 lux. Rossi would thus be correct.

Try any of the online calculators and see how it goes.
