Thread: Using LED's with stereo speakers
05-23-2011, 07:43 PM #1Using LED's with stereo speakers
This has nothing to do with idevices but I thought maybe someone on this site could help me out.
I built a cooler stereo to use at my pool area or on float/camping trips. I was wanting to add LED's to each speaker that will flash to the beat of the music. I am using an amplifier that produces 50 watts RMS @4 ohms going to each speaker. I bought some rectangular LED's at RadioShack that have the following specs:
Wavelength: 465nm (min) 470nm (max)
FW current: 20mA
FW supply: 3.2V (typical) 3.8V (max)
I was playing with one just connected directly to the speaker cable, turned it up a little too loud and let the smoke out of it. My question is what kind of resistor do I need to get the best light output but not to blow any more of them?
Thank you very much for any advice.
