I'm working on a project where I need to supply power to multiple strings of LEDs, operating at 12VDC, with a max current draw of 20mA per string.

What I'm looking for a quick and easy way to connect multiple strings to one central power source. The LED strings are terminated to spade lugs, and something like this would be perfect. The only problem is that the individual terminals aren't tied together in the example above. Basically, I need a bus bar with approximately 10 screw terminals for spade lugs, used for power distribution. It's not a high voltage/current/power application.

Any suggestions?

If screw-down commoned connection points are what you want....

The easiest thing to do would be to build your own. Buy a metal strip from a hardware store and drill a hole in it every 1/4". Then you can use 1/2" bolts (I'd go with #8 sized) with a nut to attach your lugs to the bar.
