Light fixtures having light bar elements therein. In order to mimic the size and appearance of fluorescent bulbs in existing troffer-style and surface-mount fixtures, LEDs are may be arranged on light bars with integrated lenses to both diffuse the light and shape the output beam. One or more LEDs can be mounted, sometimes in clusters, along the length of a base of the light bar which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These elongated lenses may be extruded from a diffusive material, for example, and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.
