I don't think that fan is going to be powerful enough for a 600w bulb. I use a 250w bulb with a 4" (RVK 100 A1 @ 175m3/hr) and in the summer I struggle to keep the temps low enough. I would go with a 5" fan, filter and ducting (250m3/hr) and depending on your ambient temps you may need an intake fan as well.
