Technically, a fan works better pulling than pushing.
In reality, a fan has to push the SAME amount of air that it is pulling. You can't pull a lot of air and only push a little out. The amounts are equal.
As far as the heat from the bulb causing a shorter fan life? I cannot say for certain, but it seems logical that the internal components (specifically bearings) would last longer running at a cooler temperature.
If your fan has a 3-5 warranty and you run it all the time, who cares. In 3-5 years the fan will have more than paid for itself anyway.
I'm not telling anyone to tear down their setup and arrange it different. But for people setting up a new space it is definitely something to consider.

You guys are thinking to much. Quit sweating the small stuff. Inline fans are good and cheap as hell from home-depot. Just calculate your CFMs(multiply length by width by height), upsize it by half for your outtake air and a fan that matches your CFMs for your intake. I always pull my air off the light. I don't care if over time my little inline fan may break down. It is just a fan. Made by humans. It is not going to last forever. All I care about is spoiling my girls.

You're right. You're absolutely right. I don't know what the fuck I was thinking.
I'm just going to hook it up whatever way seems easiest. Who gives a shit??? That's what a WARRANTY is for.
