If these were constructed in a way that provided better isolation of each run I would use them for higher voltage applications. But as it is I think I'll stick to using them for low voltages. Great idea though. And the springs are very string. They provide good grip on the wire. You couild probably get away with using them to wire lights but I'm not a gambler so I'll stick to something that gives me better seperation. If the body was one molded piece with solid walls between the runs they woud be even better.
