LED - Infrared 950nm (25 pack) Product Help and Resources
Core Skill: Electrical Prototyping
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.

FPV IR Headlight
I bought these to create a 24 LED Array to act as a headlight for my FPV setup and was not disappointed. 4 groups of 6 LED's can be hooked up in series with a 56 Ohm 1/4 Watt Resistor and then all fed with the standard 11.1V battery pack. Next time I build another for another aircraft I will definitely go with these.
Worked fine for controlling my TV
Used these and an Arduino Nano to script a series of remote commands to my TV. Works fine, no issues.
What's the basis of the "Resistor Value 390 Ω"?
At the rated maximum current of 20 mA, 390 Ω will drop:
V = I * R = 20 mA * 390 Ω = 7.8 V
That's more than a 4-pack of alkaline, NiCd, or NiMH cells provides to an open circuit.
At the nominal 6 V from a 4-pack of alkaline cells:
Vres = Vbatt - Vled = 6 V - 1.5 V = 4.5 V, so
I = Vres / R = 4.5 V / 390 Ω = 11.5 mA
At the nominal 4.8 V from a 4-pack of NiCd or NiMH cells:
Vres = Vbatt - Vled = 4.8 V - 1.5 V = 3.3 V, so
I = Vres / R = 3.3 V / 390 Ω = 8.5 mA
Eric
The datasheet says the max. forward current is 50 mA, but above it says 20 mA. Which is correct?
If I was to make an IR illuminator for night-vision viewing through a phone camera with all of these, would it be bright enough? Also, would 850nm be better despite the visible red glow?
Can these damage your eyes of shone directly into them 2cm away? im building an eyewriter system but don't want to damage my eyes
The real problem here is that we have no information about the intensity. It's a little late, but hopefully you didn't give yourself cataracts!
If you are worried about safety, some suggest to look at the LED using a digital camera. The IR led is good to go if you can see it glowing on the screen. (www.ehow.com has some great tutorials about testing IR Leds and safety) Hope that helps!
I'm going to go ahead and say yes, it's best not to do that.
Everybody loves IR LED's!
Perfect for the nighttime wildlife camera I'm making
Can I get a Spec on the viewing angle of these? Wide, Narrow? I need some good wide angle for a beacon implementation.
This LED might be good for IR control applications, but it won't make that next project shine (unless you have IR vision).
This is not the same LED as COM-09349, or is it?
It appears to be the same LED, but the specs do not match.
The other LED has a forward current of 50mA. This one is 20mA.
