The LED technology platform offers the opportunity to achieve energy savings beyond improved source efficiency through improved optical design, precise spectral control, and adaptive lighting. High source efficiency results in significant and measurable amounts of energy savings. The efficiency of phosphor-converted LEDs has improved enormously over the past decade. LEDs are semiconductor devices that emit light through recombination of electrons and holes by application of a forward bias across the p-n junction. The transition to LED lighting has been propelled by the profound energy, economic, performance, design and application benefits enabled by LED lighting. Today LED flood lights have become the prevailing choice for marine lighting applications. LED technology has established its dominance All HID light sources require long startup/restrike times and can be damaged by constant switching cycles. Metal halide lamps are prone to risk of explosion and have poor lumen maintenance. HPS lamps have a poor color render index (CRI). Marine flood lights that use high intensity discharge (HID) type light sources (high pressure sodium, metal halide) have improved efficiency but struggle with a set of disadvantages. Halogen flood lights are energy hungry and short-lived. Conventional flood lights, however, suffer from a number of limitations. ![]() A typical configuration of a conventional flood light includes a housing within which appropriate electrical components, a lamp and a reflector are mounted for generating and directing light in a desired beam pattern. ![]() These fixtures rely on the use of large optical reflectors to regulate luminous flux from the omnidirectional light sources. Technological obsolescenceĬonventional flood lights are lamp-based systems that are designed to control the distribution of light emitted by halogen lamps, metal halide lamps, or high pressure sodium (HPS) lamps. These aimable luminaires deliver high intensity lighting critical to the visibility of activities and tasks performed on board or around commercial vessels, navy vessels, recreational vessels, cruise ships and ferries. Marine flood lights are directional luminaires that are designed to project a controlled beam of light to illuminate the deck or other areas below.
