    Caps out of HID lighting ballasts should be suitable. IIRC, the 
typical 400W Metal Halide (ANSI M-59) fixture has a 24uF 400+V cap in it.
    Keep in mind (if you're scrounging from junk fixtures) that the 
cap seems to be, in about a third of the cases, the item that "dies" 
to kill the fixture. Check that the cap measures its correct value 
before using. They are designed to fail "open", but in my experience 
that doesn't happen too often.

    Motor rewind/repair shops usually stock run caps as well.
