Powering an led?

Ft13 · Aug 3, 2014

I ordered this led:

How would I power it? I'm trying to avoid 2x9volt batteries. I'd rather use 1 battery.

While I'm on the subject, which resistor should I use with this?

Thanks in advance!

The forward voltage of that LED is rated at 15.1 volts, so unless you want to build/find a boost circuit to power it from a single battery I think your out of luck as I've never seen a 15 volt battery....

What is the application you want to use this LED for? You can get yellow LEDs that are just as bright or brighter that have a lower forward voltage so you could use a single battery like a 3.7 volt li-ion type.

I found a 15 volt battery on amazon for $10.

This is for an art project. I'm doing the head of Shockwave from Transformers, so I needed a bigger LED than the normal 3mm or 5mm.
