    Pros: Small, powerful, easily mounted, bright Cons: Needs high current at low voltage (but see below) OtherThoughts: Nice bright LED, at least for an IR camera. With your normal eyes you only see a faint red glow (do not look into the LED directly!). I drive it with 1.75A, voltage is then 1.66V 5... 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 no... Read more
