If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components. See all skill levels. We welcome your comments and suggestions below.

However, if you are looking for solutions to technical questions please see our Technical Assistance page. I wired up 3 of them to make a night vision webcam for my aquarium. I had them going at about 45mA but 3 was only sufficient enough to illuminate a small area of the tank. Any change in the distance? The difference is effectively the color of the light that it outputs, in the same way that a green LED is different than a red LED.

Since both and nm are infrared, assuming you're human, you can't see the difference a snake could probably tell you. But in terms of selecting one or the other, you should get the one that corresponds to what your receiver is looking for. Check those specs first, then get the matching LED. Mike's right, there's not much difference as far as the IR usage so long as you match your receiver.

If it doesn't matter for for the receiver, one thing I ran across is that the nm might be useful to know, yes most of the light is out of the visible range, but without a filter or anything, you'll likely be able to see a very faint red glow from them in the visible range. I'm actually about to take advantage of this because out of laziness I want an IR illuminator that I can visually confirm has power without pulling out my camera on my phone. Nearest R12 series: Ohm. The reason I mention the 20mA is because the Arduino pins don't really want to deliver the full 50mA that these are rated for see also the Illumitune tutorial link.

This may or may not be an issue for your purposes - at 20mA it'll be a fair bit weaker the datasheet doesn't specify how much weaker, though. If you did want to drive it at 50mA, you'll want to use a transistor or the like to toggle power to the LED.
