I'm looking to put lights in a shadow box/frame, and I thought it would be fairly straight forward, but as with most things, I think I have underestimated what I need to actually do..
I have purchased white and red of these LED's off eBay:
**broken link removed**
As you can see with those LED's, they're 3-chip, and I initially thought about connecting one side of a resistor wire across the 3 terminals, but now I'm thinking that I'm supposed to put a resistor to each chip of the LED? I just want them all to light up at once. Can I get away with soldering the resistor across the 3 positive terminals? Basically connecting them all to the one point, if that makes sense..
Also, I am going to be powering 14 LED's at a time, and I want to run it off batteries... Would it be ok for me to just connect each LED in parallel with the power supply? I was thinking of using 6V (4 x AA batteries), as I don't want the batteries to take up much space.
Sorry for writing so much, but I like to make my question clear, so hopefully someone will take the time to read through it..
Thanks in advance
