Pros:
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! :-)).
Cons:
It is not 100% invisible so you can see that it is on. Requires heatsing to operate...but it is normal with high power LEDs :) Hard to find driver to operate because of low voltage
Other:
Again - buy this only if you know what you are buying. IT is only DIY part so have some experiences with electronics!
Bottomline:
Good thing as light for surveillance cams even it is slightly visible.
