Temperature is an important consideration.Ĭolour temperature is measured in Kelvin andĭescribes the effect of heating an object until When selecting LED interior lighting, colour LEDs had a reputation for appearing ‘cold’Īnd ‘blue’ due to there phosphorous coatingĭevices can rival traditional incandescent light Of LEDs for general marine lighting purposes. The major factor preventing the acceptance LED devices with sufficient intensity has been Until recently, the lack of high quality white The supplier’s warranty policy, integrity and track record is often a more accurate benchmark on the lifetime and quality of the LED lamp under consideration. In the harsh marine environment, salt air corrosion to circuit boards, light degradation due to excessive heat, vibration fatigue, shock loads, voltage fluctuations and low battery voltages all contribute to reduce the operating life of LED lamps without thorough engineering and electronic protection. These lifetime estimates are often based on LED component specifications from the device manufacturer rather than the life of the complete lamp in a marine installation. The high power LED devices are often too new to have been thoroughly tested for such periods. Many LED lamp manufacturers claim operating lifetimes of 50,000 or 100,000 hours, however in many cases these claims are generalized. Hella marine LED products feature several key advantages such as completely sealed housings, sealed cable entries, effective electronic protection, shock, vibration and impact resistant components that all contribute towards outstanding reliability. Compared to incandescent lighting, where a filament inside a bulb may break at any moment, Hella marine LED lighting is ‘fit and forget’. Less than 0.8W yet produces the equivalentĭue to their solid state nature, LEDs do not have filaments to break, however LEDs do require precise current regulation and voltage protection to provide long term reliability.įor LED lighting manufacturers, many design and engineering milestones are required to produce durable products that provide ongoing performance in marine applications. Maritimo 73 system are the compact 'Rakino' The majority of the lamps specified for the With the safety aspects of an almost zero heat Reduction in cable size and weight together Illuminate the same interior layout with halogen LED lighting system specified for a Maritimoħ3ft motor yacht draws less than 7 Amps. Save hundreds of amp hours is available now.Īs a recent example, the entire Hella marine Is the considerable power saving on offerĮlectrical architecture where consumption canīe dramatically reduced. The single most influential driver for LED The following are key considerations when selecting LED lighting for marine interior and exterior applications. Significantly reduced power consumption, increased reliability, reduction in radiated heat and attractive ambient effects are all benefits of modern LED lighting systems. Quality LED lighting provides many significant advantages over traditional filament based sources. Easily visible LEDs inside a luminaire without any optic or lens protection can cause a degree or even significant eye discomfort if viewed directly. It is desirable for the entire lens area of a lamp to be evenly illuminated via an efficient optic rather than using a multiple of LEDs without any optic. It is essential for high power LEDs to be coupled with optic designs that protect the eye's retina from possible damage when viewed directly. With significant advances of LED brightness, eye safety considerations are increasingly important. To take advantage of the ever increasing efficacy of the most advanced LEDs, efficient optic design is essential to capture and spread the available luminous flux emitted by the LED and to evenly illuminate areas. Recent quantum leaps in the luminous intensity of LEDs per watt have allowed marine lighting systems to develop significantly to effectively illuminate a vessel's interior. Hella marine LED lighting products are sophisticated opto-electronic devices designed for durable, energy efficient, maintenance free operation.
