Just how badly did I damage my new projector?

TIFU. I made an unfortunate series of fuckups with my brand new BenQ HT2050A while setting it up:

• Firstly, I didn't push the power cord in all the way when I first set it up. I thought it was in all the way, but later found out that it needed a lot of force to go in fully.

• While adjusting its position and keystoning to fit my setup, I moved its position a bit, which made the slightly loose power cord lose its connection briefly, cutting power to the projector.

• I knew this was bad since it couldn't do its cooling cycle, but I didn't know what to do about it: let it cool naturally or turn it back on for the fans to power up and cool it actively? I panicked for a bit, then made the wrong decision: turning it back on after about a minute, thinking the fans turning on would help.

It still seems to work perfectly with no signs of issues, so I thought I had dodged a bullet. But after researching online, I see that what I did was not good and probably shortened the life of the bulb - which I somehow managed to do before even getting the first hour of use on it - I can't believe my stupidity! Just how bad would you say this was?
