I have a 2 strobe mini lightbar, with inclosed power supply. I want to add a forward facing stobe light to it, but it ony has 2 outlets on the power supply.

Can I wire the 2 omni-directional strobes in paralell off 1 side of the power supply and the directions strobe off the other side of the power supply? I realise that this would cut the light output of the 2 omni-directional strobes, and that would be fine, but I'm not sure if the tubes or power supply can handle it.

I don't see why you can't do it, I've run 10 strobes on a 6 outlet pack before. Didn't have any problems.

I suppose you could, but light output will dimishish quite a bit, and you will shorten the life of the power supply. Depending on the wiring used internal to the bar, running too much current could cause a problem.

What bar?

Not a good idea...

Buy the right PS or get a 2 ch you can cram in the bar.

i agree with pj. i have tried it and the lighting output is diminished. get your self a remote power supply and you can run as meny lights as the power supply will let you.

Another issue when paralleling flashtubes on one output is the sharing of the trigger pulse. As the tubes age, and need more trigger voltage to fire, one or both of them will get flakey about firing. One may not fire, or they may do some strange alternations.
