Metal halide sockets and connects should be pulse rated for 1500V,
iirc. I don't know what the starting voltage is for a T5 or T8
fluorescent lamp is with an instant start ballast, but I'll bet it is
close to 1000V. So 600V connectors are probably OK, but they are also
probably marginal. Just be careful.
