How to change a lightbulb

I have big spotlights in the ceiling.  I have a partition between the bedroom and the shower.  Basically just a rail for sliding doors.  The shower light failed.  Here are the steps I went through to change it.

The partition was put in after the shower so I couldn't extract the bulb.  I tried unscrewing the partition but it still didn't budge.  I had to go into the loft and dislodge the light fitting just to get the thing out.  I'm sure changing a frikken lightbulb shouldn't have been so hard.
