Throws off a lot of infrared light Gets very hot Need high thermal rated resistors High current compared to normal leds Used to make a sensor bar for my wii that runs off the computers USB port. Pretty sure the power requirements are way out of the usb spec, so I don't know if the led isn't shining at full brightness or if my ports are supplying more ... Read more
The performance from this LED is amazing! I wired this to a 2 volt sealed lead acid battery as suggested by dav850, but lost my nerve, as the battery was brand new and reading about 2.36 volt open-circuit, so I opted to limit the current with 5 x 5 Ohm resistors in parallel (they were only 1 watt each). The output was stupendous and more than able to ... Read more
Very bright infrared LED. Well it is bright on camera. with naked eye you can see only little red and nothing else. But you you see through camera, you can see it is very bright. It is bright enough to pass through my finger and it looks like x-ray! :-)). It is not 100% invisible so you can see that it is on. Requires heatsing to operate...but it is ... Read more

Cheap, really cheap it is an emmiter of invisible light but when it is on, you can see than ir turns a little red, but no more.
You need some sort of protection, I tested ... Read more
