/diy/ - Do It Yourself

is the power output of these things legit or are they scamming?

when checking for diodes, the highest output I could find for 850nm leds was 1300mW/sr
I made a model of their product and the maximum amount of leds that have beam overlap is ~175(90 degree beam angle at 6”)
even assuming they carry 100% output for entire beam area, it’s still dispersed on ~730cm2@6” out.
If each led can only deposit 1/730th of 1300mW on a given cm2, so it ends up being something like 0.3W/cm2
Am I doing something retarded in my calcs or is this shit a scam by a factor of like 500?
