A LED lamp (1) having an air-cooled heat sink (6) enclosed in a housing (2) having a front section (3) and a rear section (4) that holds at least one LED (5) connected to the heat sink. A plurality of cooling vanes (7) extend from the heat sink and heat generated by the at least one LED travels through the heat sink and then through the cooling vanes. The cooling vanes create additional surface area for air to come into contact with, thereby allowing more efficient cooling of the at least one LED. Cooling channels (8) located between the cooling vanes allow for air flow between the cooling vanes. Further, the cooling vanes are angled so that a venturi effect is created as a fan (13) pulls air through the cooling channels, thereby increasing the airflow across the cooling vanes.
