1. A flashlight comprising: an elongate housing extending along a longitudinal axis and having a forward portion with a forwardly facing surface and a rearward portion; cooling fins of the forward portion of the elongate housing; a forwardly facing opening in the forwardly facing surface, the cooling fins disposed at least partially around the opening;a power source disposed within the housing; a switch device mounted to the housing;a LED disposed in the forward portion of the elongate housing and mounted to project light through the opening, the LED electrically connected to the power source and the switch device so that the LED can be selectively energized;wherein the LED is mounted within the forward portion so that the cooling fins dissipate heat generated by the operation thereof, the housing has a three-piece construction with the forward portion, the rearward portion, and a middle portion being formed as the three pieces that are separably assembled together, and the middle portion includes a power source compartment and the rearward portion includes one or more through openings to access the power source compartment. 2. The flashlight of claim 1, wherein the power source is a rechargeable power source, and the through opening includes a port for recharging the rechargeable power source. 3. A flashlight comprising: an elongate housing extending along a longitudinal axis and having a forward portion with a forwardly facing surface and a rearward portion;cooling fins of the forward portion of the elongate housing;a forwardly facing opening in the forwardly facing surface, the cooling fins disposed at least partially around the opening;a power source disposed within the housing;a switch device mounted to the housing;a LED disposed in the forward portion of the elongate housing and mounted to project light through the opening, the LED electrically connected to the power source and the switch device so that the LED can be selectively energized;wherein the LED is mounted within the forward portion so that the cooling fins dissipate heat generated by the operation thereof, the housing has a three-piece construction with the forward portion, the rearward portion, and a middle portion being formed as the three pieces that are separably assembled together, the forward and rearward portions of the housing connect together capturing the middle portion therebetween, and the forward and rearward portions of the housing connect together using fasteners extending through the middle portion. 4. The flashlight of claim 3, wherein the middle portion includes interior channels on opposing sides thereof sized to receive the fasteners therethrough. 5. A flashlight comprising: an elongate housing extending along a longitudinal axis and having a forward portion with a forwardly facing surface and a rearward portion;cooling fins of the forward portion of the elongate housing;elongate slots between the cooling fins;a forwardly facing opening in the forwardly facing surface, the cooling fins disposed at least partially around the opening;a power source disposed within the housing; a switch device mounted to the housing;an LED disposed in the forward portion of the elongate housing and mounted to project light through the opening, the LED electrically connected to the power source and the switch device so that the LED can be selectively energized;wherein the LED is mounted within the forward portion so that the cooling fins dissipate heat generated by the operation thereof, the cooling fins and elongate slots therebetween extend rearwardly along the longitudinal axis from the forwardly facing surface with the slots opening at forward ends thereof to the forwardly facing surface, the cooling fins and elongate slots each also extending laterally outward in a lateral direction relative to the LED with the cooling fins extending laterally parallel to one another and the elongate slots extending laterally parallel to one another, and the housing has top and bottom wall portions having flat, parallel outer surface portions and curved sidewall portions extending between the top and bottom wall portions and at which the elongate slots open, the curved sidewall portions being smaller than the top and bottom wall portions so that a distance between the flat, parallel outer surface portions is smaller than a distance between the curved sidewall portions to provide the housing with a narrow configuration between the top and bottom wall portions, the cooling fins extending inwardly from the curved sidewall portions on either side of the opening. 6. The flashlight of claim 5, wherein the opening is generally centrally disposed in the forwardly facing surface, and the cooling fins extend transversely to the longitudinal axis of the housing in the lateral direction to surround a majority of the opening. 7. The flashlight of claim 5 wherein the power source is a rechargeable power source, and further comprising a solar panel mounted to the housing and configured to provide recharging power to the rechargeable power source. 8. The flashlight of claim 5, further comprising a charge measuring circuit electrically connected to the power source and configured to monitor a charge status of the power source, the charge measuring circuit including a transmitter configured to send a charge status signal to an external computing device. 9. The flashlight of claim 5, wherein the housing has a three-piece construction with the forward portion, the rearward portion, and a middle portion being formed as the three pieces separably assembled together. 10. The flashlight of claim 9, wherein the forward and rearward portions of the housing connect together capturing the middle portion therebetween. 11. The flashlight of claim 9, wherein connections between the forward, middle, and rearward portions of the housing include seals therein such that the housing is waterproof.
