A light bulb includes an Edison style base, light emitting diode circuitry coupled to the base, a bulb sealed about the base and extending above the base, an elongated filament substrate supported by the base and extending into the bulb above the base, a light emitting diode channel supported by the filament substrate, coupled to the light emitting diode circuitry, and extending into the bulb above the base, and an inert gas disposed within the bulb.
