I'll say! I'd want to include a lamp limiter - a 100W bulb would be about right
That's presumably a reference to the very poor state of the average R1155, and the fact that many new owners will just want to connect up a power supply - just "to see what happens"!

That could easily result in the demise of various bits inside the R1155 - or the power supply. Which is the main reason I refused to go with any semiconductor regulator when I was designing a power supply for this job. Far too easy to blow up the supply - particularly with inexpert users.
