218 SERIES

      The 218 SERIES is a kind ofFILAMENT REPLACEMENT LEDs - Multi-LED Cluster. Some  design considerations are as follows. First, all devices feature water clear high intensity LEDs as standard. Second,  filament Replacement LEDs have been specifically designed to meet the primary objective of providing improved reliability.As 218 SERIES range is suitable for both new-build and retro-fit, (sometimes in very old systems), a wide range of illuminated push button switches and lamp holders can be encountered. Third, build up of electro-static discharge occurs in many situations involving people moving and handling products. The range of possible situations is very diverse but voltage levels as high as several thousand volts can and do arise in many individual situations. Fourth, the forward voltage/current value of an LED is dependant upon the ambient temperature of the environment in which it is operated.
      Next is some technical information about the 218 series. Its Lamp Base Style is E26 Filament Base, its Metric Equivalent is26 mm,and the Maximum Power Dissipation is 2500(mW).
      Here are some features of 218 SERIES . The first one is Direct replacement for E26 (North American Standard), the second one is 20 LED Cluster, the third one is  BA22 (UK) and E27 (Europe) versions also available, the last one is  Optional polycarbonate lens.
      Some notes of 218 SERIES are as follows:First, Products must be derated according to the derating information. Each derating graph refers to specific LEDs. Appropriate LED numbers shown..Second, Intensities (lv) and colour shades of white (x,y co-ordinates) may vary between LEDs within a batch.At present there is not too much information about this model.If you are willing to find more about the 218 Series , please pay attention to our web!
