Anyone know of really good high intensity IR LEDs?
From what I understand, what I should be looking for is high mW/sr.
This is the highest I've found so far: http://ca.mouser.com/ProductDetail/OSRAM-Opto-Semiconductors/SFH-4740/?qs=sGAEpiMZZMtjb30GAx%2fDT1U8V3wx9ak79OV%2f1mC1P3I%3d
Cooling or voltage/current is not important, just the highest output possible.
(this is for night vision, so 850mW)
Thanks! :)
osram fo sure? but you want the…
4715AS… has the best power and angle… we tried them ALL…
It says total radiant flux is 2000mW, which is less than half of the 4740/61?

for reflector lights
those have a 1x1mm die
4715as ? has a +/- 45 degree half angle… its pretty tight…
its small diameter led size? well…. it makes it the “thrower king” because of that… we mainly use it under lenses… i guess if you want a flooder?? something else might suit you… hard to go WRONG with a 4715as, though…
its sort of a “number 2” in cree terms… takes double the current of the 4715s that it replaced… with a better “focused emitter” picture…
may i ask what DEVICE you want it for?
I’m planing to put it on a UGV with an fpv camera, the IR will give it night vision.
It’s not a typical flashlight, so I can pretty much use any optic or cooling I want.
High output flood is the main goal 
idont know WHAT a “ugv” is… but, if you want flood? go with whatever blasts out then, lol… i was figuring you might be using a zoomie… which is typical for night vision…
Ok cool, thanks.
btw UGV means unmanned ground vehicle.
