Abstract
Lantern employs clear lens protective cover around the drum lens and a clear dome over the solar panel mounted above the lens. A heavily damped gimbal supported by the lantern housing mounts the lens, lampchanger, and flasher above a bank of batteries suspended from the gimbal. The weight of the batteries aids in providing a righting moment to the gimbal when the marine buoy, atop of which the lantern is secured, is tilted or inclined for sustained periods due to current and/or wind. Interior of the lantern is readily accessible by merely pivoting upwardly an annulus supporting the lens cover, solar panel, and dome.
