Thanks oreo. Glad we connect on this.

I have a separate thread where I measure the power and PAR of different multichip LEDs and I've come to the conclusion that DIY fixtures are not all equal. Different chips from different sources are significantly different from their "ratings"

Any design that isn't confirmed with a PAR measurement is a wate of time.

I wonder what the statistical distribution of PAR and wall-plug efficiency in commercial LED fixtures would look like vs. their promise.

What I'm getting at is that the variability in LED results across different users may be because LEDs can be individually different.

It's not that LEDs are worse than Halides... It's that your specific LEDs are inferior compared to my Halides or my LEDs. Someone else buying the same fixture may have gotten a better batch of chips.

Without measuring PAR, it's a crapshoot.
