I currently have 4 Under cabinet fluorescent fixtures each 4 foot in length, controlled by one single pole switch. My goal is to be able if possible to control each fixture independently. Would this be possible with the new micro modules and a 6 button keypadlinc? Thanks

There would be no insteon limitation. The only problem I would be concerned with is ability to safely install modules. Do you have access to the wiring? Do you have box space in which you can install a module for each fixture?

I believe that the modules are small enough to be installed within the metal body of each fixture.. Would the modules work inside the fixture (the part that houses the ballast etc)

Insteon communicates primarily (in my mind) via powerline. INstallation within light housings should work well. It is no worse than metal electrical boxes. All your devices are on the same circuit.

 

Some floursescent lights can interfere with insteon communication, but my best guess is that you will be fine here. If not, this is nothing that a couple of inexpensive filters cannot fix.
