An LED retrofit tube that has an outer body that is substantially a lens so as to enable light generated by LEDs and light reflected therewithin to pass through substantially the entire tube. The tube includes an extrusion to support a circuit board having light emitting diodes (LEDs) mounted thereto. The extrusion is located substantially with the lens. The circuit boards may include LEDs mounted on both sides to provide primary lighting and secondary lighting (backlighting). The extrusion may include grooves to allow the backlighting to pass therethrough. Rotational endcaps include an inner portion and an outer portion that can rotate with respect to one another to enable the tube to be rotated and the light dispersed therefrom to be focused.
