210 SERIES

      The 210 SERIES is a kind of FILAMENT REPLACEMENT LEDs - T3¼ MES E10. Some  design considerations are as follows. First, all devices feature water clear high intensity LEDs as standard. The single chip LED devices have been modified by the removal of the domed portion of the encapsulation (flat-topped) to provide even illumination of switches and annunciators. Second,  filament Replacement LEDs have been specifically designed to meet the primary objective of providing improved reliability.As 210 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 210 SERIES is dependant upon the ambient temperature of the environment in which it is operated.
      Next is some technical information about the 210 series. Its Lamp Base Style is Minature Edison Screw T3¼ E10 ,and its Metric Equivalent is 10 mm, The Maximum Power Dissipation is 625(mW).
      Here are some features of 210 SERIES . The first one is Direct replacement for T3¼ Midget Edison Screw E10, the second one is Centre contact anode as standard, the third one is  Ideal for industrial pushbutton switches and annunciator panels,the fourth one is Flat-topped to ensure total lens illumination  the last one is Warm White LEDs may be used behind coloured lens as a true replacement for a filament lamp.
      Some notes of 210 SERIESare as follows:First, Please note that this product is also available in different voltages. Contact our sales department for further details. Second, Products must be derated according to the derating information. Each derating graph refers to specific LEDs. Appropriate LED numbers shown. Third, Intensities (lv) and colour shades of white (x,y co-ordinates) may vary between LEDs within a batch.
