Systems and methods are provided for deriving power for an external device
from a circuit of a fluorescent light. A first circuit supplies power
from a fluorescent light power source to a fluorescent lamp. The power
converter of an external device can be electrically connected to any two
points within that circuit to create a second circuit to supply power to
the external device. The power converter may be connected to the first
circuit via one or more power coupling or power tether. At least one of
the two points within the first circuit may comprise a pin of the
fluorescent lamp. Alternatively, at least one of the two points may
comprise a connector of a fluorescent light fixture designed to receive a
pin of the fluorescent lamp or a point within the fluorescent ballast of
the fluorescent light fixture.
