Disclosed herein is an LED-based light for replacing a fluorescent bulb in a conventional fluorescent light fixture. The LED-based light includes a housing having a first end opposing a second end, a circuit board disposed within the housing and extending along a longitudinal axis of the housing, at least one LED mounted to the circuit board, at least one end cap disposed on one of the first and second ends of the housing, the end cap including a switch and at least one electrically conductive pin configured for physical and electrical connection to the light fixture; and circuitry configured to provide a current path between the at least one LED and the at least one electrically conductive pin, wherein the switch is configured to selectively disconnect the current path.
1. An LED-based light for replacing a fluorescent bulb in a conventional fluorescent light fixture comprising: a housing having a first end opposing a second end;a circuit board disposed within the housing and extending along a longitudinal axis of the housing;at least one LED mounted to the circuit
1. An LED-based light for replacing a fluorescent bulb in a conventional fluorescent light fixture comprising: a housing having a first end opposing a second end;a circuit board disposed within the housing and extending along a longitudinal axis of the housing;at least one LED mounted to the circuit board;at least one end cap disposed on one of the first and second ends of the housing, the end cap including a switch and at least one electrically conductive pin configured for physical and electrical connection to the light fixture; andcircuitry configured to provide a current path between the at least one LED and the at least one electrically conductive pin, wherein the switch is configured to selectively disconnect the current path and is selectively engageable between a first and at least a second position, the switch configured to create an open circuit condition in the current path in the first position and create a closed circuit condition in the current path in the second position; anda pin cover configured for travel between a protracted position and a retracted position, the pin cover configured to substantially enclose the electrically conductive pin in the protracted position and to expose the electrically conductive pin in the retracted position;wherein the switch is coupled to the pin cover and configured for engagement between the first and second positions in response to travel of the pin cover such that the switch is engaged in the second position when the pin cover is in the protracted position and is engaged in the first position as the pin cover travels from the protracted position to the retracted position. 2. The LED-based light of claim 1, wherein the at least one end cap includes a first end cap and a second end cap, wherein the first end cap is disposed on the first end of the housing and the second end cap is disposed on the second end of the housing, wherein the second end cap includes at least one electrically conductive pin configured for physical and electrical connection to the light fixture, and wherein the current path includes the at least one LED and is formed between the first and the second end caps. 3. The LED-based light of claim 1, further comprising: a latch configured to releasably secure the pin cover when the switch is engaged in the first position; anda biasing mechanism configured to urge the pin cover toward the protracted position. 4. The LED-based light of claim 1, further comprising: means for retaining the switch in the second position. 5. A method of installing the LED-based light of claim 1 into a conventional fluorescent light fixture, the method comprising: engaging the switch in the first position to disconnect a current path provided by the circuitry;positioning the at least one end cap's at least one electrically conductive pin into the light fixture; andengaging the switch in the second position to connect the current path. 6. The method of claim 5, wherein the pin cover is composed of an insulating material and is configured to selectively expose and substantially enclose the at least one electrically conductive pin in response to a force applied to the pin cover, the step positioning the at least one end cap's at least one electrically conductive pin into the light fixture further comprising: applying a force to the pin cover such that the pin cover is retracted to expose the at least one electrically conductive pin by pressing the pin cover against the fixture. 7.
