He could also be violating insurance on the house, and if something were to happen they may not be covered because of this.
It actually does sound like he is within the proper limit for electrical rating for that one 15W light bulb, but I definitely could be mistaken. Here is a link to the datasheet for this pull in case anyone wants to check for themselves: http://www.silentknight.com/CatalogDocuments/350792.pdf
Even so, it must be somewhat of a pain resetting that pull every time you want to turn the lights off, especially since the handle on that pull doesn’t automatically reset itself. :lol:
