Looks like the Polarion handheld HID searchlight people have finally been bested and the LED is now starting to rule.
Correct or Wrong?

I dont know............running for an hour(or so) at full power, HID can still kick LED's a55's in the distance game too.........Thats from an LED guy.
Agreed
high output leds are great for bragging rights, but if it can only do it's maximum output for 2 minutes or so before it ramps down either due to thermal or step down regulation, it's not going to compete well with something that gives consistent output for long run times.
I forget which site it came from, but this chart shows the Polarion HID (think it's the PH40) wasn't very good at maintaining it's output at all.
Edit: Here it is, referenced from this CPF post:

Still, I'll take a wash of 4000+ steady lumens in about the same form factor as the Polarion PH40 anyday.
BTW: Have you seen this 11000 lumen Pop Can thread?

I wouldn't, but I am interested. Which Single LED based light are you talking about that puts out 4000+ lumens in a steady output like the 3000 lumens of steady output shown in the graph above?
I would expect that even the Cree XHP70 would struggle to keep that kind of output without some form of effective thermal management. I'm sure it's doable, I would like more info on it.

Yes, that's very impressive. But a light that uses your hand as thermal regulation is not the sort of thing I'd want to take to a work environment.
