What sort of vold/amp etc do I need for a power supply with 2-5 of them. I have a lot of wall worts around here.
But my thought was to get something fancier that would allow me to dim them...
Haven't seen those much cheaper. You might be able to save a few bucks on ebay.
On those strips, they draw 640mA each. Multiply that by the number of strings you want to run in parallel and that's the minimum current you need for the power supply.
