Here’s my (German) thread where I calculated that.

Nah, I calculated that myself over a year ago

Brightest LED chip?

Hey, I'm wondering if anyone knows what the brightest LED is, I might be interested in making a single-led floodlight in the future. So far the best I've found is the Luminus CXM-32:Gen 3 at 19675 lm. Second best is the Cree XLamp CXB3590 at 18k lm. I checked Nichia and found some slightly smaller LEDs with about 11k lm. I don't want one of those cheap chinese square LEDs that advertise 100W or whatever and then end up having a bunch of the inner dies not working (picture for reference), …

When you drive it at 2x the base spec you get the 500W 70k lumens.
Still really good efficiency, over 100lm/w, assuming it is cooled properly.

That shouldn’t be a problem if the pump is after the radiators unless the radiators can’t provide adequate cooling.

Temperature difference before and after a radiator is a fraction of a degree, unless you have a really weak pump and low flow rate.
