I made some color test lighting set of thinks with different light sources:
1. Sun light in room with neutral color walls and ceiling.
2. SST40 5000k LED in convoy flashlight. Battery current (LED has consume same) was around 2A.
3. SST20 4000K LED in convoy flashlight. Battery current (LED has consume same) was 1.75A.
4. LH351D 4000K LED in sofirn HS05 flashlight. Battery current (LED has consume same) was around 2.3A.
5. GT-FC40 4000-4500K LED in convoy S11. Battery current (LED current is unknown) was around 3.2A.

White balance was fixed to day light.
All flashlights have different light beams.
So try to not notice to light level, shadows, color temperature.
Just notice to color differentiation into each scene. Are the colors distinguishable?

Red and brown are definitely off on sst40. FC40 looks less yellow than the others.

Sorry for some mistake. I took photos in auto white balance mode. Fortunately I took them in RAW and there is new set of photos with day light WB.

I’ve just read a review on Reddit of the Acebeam E70 CRI with the GT-FC40 but can’t see it on Acebeam’s website.

It is the option that says “CRI95+ 4500k 2800lumens”.

Hi djozz. It is possible to share file or table with your measurements. I want to try to make pcspice model of FC40.

This is an oldie, but I'm a rebel like that. Wink

 

That SST40 looks fantastic, I'm quite surprised. 5000k is definitely where it's at (k temp rating of the sun, so....) 

 

Has anyone published a watts:lumen chart for today's popular LEDs?

It's quite possible! I caught the:

 

"SST40 5000k LED in convoy flashlight. Battery current (LED has consume same) was around 2A.
3. SST20 4000K LED in convoy flashlight. Battery current (LED has consume same) was 1.75A.
4. LH351D 4000K LED in sofirn HS05 flashlight. Battery current (LED has consume same) was around 2.3A.
5. GT-FC40 4000-4500K LED in convoy S11. Battery current (LED current is unknown) was around 3.2A."

 

But I missed a table containing XPL Hi, XHP70.2/3, random Nichia, random OSRAM, perhaps others. 

 

I definitely missed at what level those current readings were taken. I'll reread, because I assumed they were all on low, given the photos.
