thinking about making my own rack also and want to put in a overcurrent (surge) protection. I am going to simply put a inline fuse on one leg of the lamp cord with about a .5A fuse on there (depending on the type of FW). For example, lets say 1 foot of 11" FW @ 20W. 20W at full on will draw about 170mA (p = v*i). So the way I figure, if that thing starts to pull half an amp it's toast (thats about 60W).
