The 4522 bulb is a 250 watt bulb at 13 volts.

He wrote 4552, not 4522. The 4552 is a 28v 250W part, putting the current
at below 10A. A 20A breaker ought to be entirely sufficient.

If his post has a typo, and he actually means a 4522 bulb, then of course
your post offers very useful information.

Here's what the original poster said in a subsequent post in
rec.aviation.owning:

Nobody looks it up. The 4522 lamp is usually used in a swing-down
lamp.

The landing lamp is a GE 4522.

If I posted different, then it is my error and I appologize.

I assumed a typo right off, since I knew of no 4552 in any 172s.

And after Jim Weir razzed me, I doublechecked the Cessna parts
manual again, and for a whole serial number range they call for a 4522
bulb on a 20 amp breaker. They DO make mistakes sometimes.
