a bracket comprising;

a connector; and

a housing rotatably coupled with the bracket and comprising;

a light emitting diode connected to the connector; and

a fan connected to the connector.

2. The light emitting diode-based bulb of claim 1, wherein the light emitting diode and the fan are connected to the driver via a single electrical connection.

3. The light emitting diode-based bulb of claim 1, wherein the housing further comprises one or more vanes arranged for thermal transfer away from the light emitting diode.

4. The light emitting diode-based bulb of claim 1, wherein the housing is slidably coupled with the bracket.

5. The light emitting diode-based bulb of claim 1, wherein the bracket is U-shaped.

6. A method of servicing a light-emitting diode-based bulb comprising:

decoupling a bracket and a housing of the bulb;

electrically disconnecting the decoupled bracket and housing;

electrically connecting a new housing and the bracket; and

coupling the new housing to the bracket.

7. A light emitting diode-based bulb comprising:
