780-80
CFL FRIENDLY J-BOX INFRARED RECEIVER
The 780-80 is a CFL (compact fluorescent light) friendly
version of the 780-10 J-box series IR receivers. It is
specifically designed to have great immunity to high
frequency ballasted CFL and overhead fluorescent
type infrared interference and to have exceptional IR
reception range. In addition, the 780-80 will operate in
direct sunlight!
It mounts easily into a single gang electrical J-box and
is supplied with mounting screws and a dark red lens
insert allowing the installer to use a Decorator-style
wall cover plate.
