I just bought an Odyssea PC fixture that can output up to 130W (two 65W bulbs), plus it has a built-in cooling fan and
LED "moon lights". Bought it from eBay, all things considered cost me less than $100. My corkscrew val has taken off in the few days I've had it up.
It's pretty much the same as the Coralife dual PC fixtures, but cost about half as much. Odyssea used to make some bad fixtures with magnetic ballasts that went bad really quick (in flames sometimes), but in the last few years they've been using electronic ballasts that haven't had any problems. Also, they're a Korean company, so support isn't an option.
