Claim 11:
12. A lamp comprising:
a light source including at least one string of light emitting diodes within a tube body;
end caps having contacts with a G13 pin layout at each end of the tube body;
driver electronics including a filament detector portion provided by a passive resistance capacitor (RC) circuit that simulates the filament load of a fluorescent lamp when installed into a ballast containing fixture; and
a power level selector switch for selecting light characteristics for light emitted by the light source the power level for powering the light source, the power level selector switch actuates a transistor for selecting different power levels according to select resistors connected to the transistor to control current to the light source.
