Those lamps are already more than I could hope for. Their ability to get waterlogged, the way you coded them to change wether they're hanged on ceiling or walls or put on the ground where a lot of modder just add an item for each position, and most of all that edge conforming lamp is a must have.
But you did code the block lamps to switch on and off with redstone. And i love to be able to swich lamps on and off in a modern house, keeping only the currently occupied rooms lighted. (Of course then one of the mob control mods is needed). 
So I would really love for all the lamps to get swichables
