    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    very bright infrared led

    well, it is not really brigt because it is invisible for the human eye, but it is not invisible for almost all ccd or cmos cameras and that is how I tested it.

    Cheap, really cheap

    Cons:

    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 and play with it for about 30 minutes and after that my eyes were hurting (I know I should have known, but I did not think that would happen that).

    It consumes a lot of current so you need a really powerful source. and it really gets hot.

    OtherThoughts:

    It cold be used for spy cameras night vision.

    Bottomline:

    It arrived 8 days after I order it, so it was a very fast delivery

    by the way I used 8 resistors of 8.2 ohms @ 1/2W instead a resistor of 1ohm @4W and it worked fine
