Abstract: The present invention relates to different embodiments of lighting fixtures, such as high bay lighting fixtures, comprising improved features. One of these features can be a driver box placement that is displaced from the center of the fixture. In one such embodiment, the driver box can be mounted such that no portion is over the emitters. Another improved features is a heat sink with branching spokes. As they move away from the center of the heat sink, each of the spokes can branch into multiple spokes, which can improve conductive thermal dissipation. Empty spaces can be left between the spokes to improve convective thermal dissipation.
