design considerations  
Single-Chip LEDs  
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. Non flat topped versions are also available.  
Product Evaluation  
Filament replacement LEDs have been specifically designed to meet the primary objective of providing improved reliability. As  
this product 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. Due to subjectivity, evaluation of the LED type is recommended,  
(samples of all standard models are available). Care should be taken to correctly simulate operating ambient light conditions to  
ensure that the correct device has been selected to maximise viewing characteristics such as viewing angle, colour  
compatibility and on/ off contrast ratio.  
Electro-Static Discharge (ESD)  
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. When an operator charged up to these levels handles a static sensitive device, there is a very probable likelihood  
that the device will be irreversibly damaged. It is essential that precautions are taken at all stages during manufacture and  
assembly of these products. Although LEDs were never considered to be static sensitive devices, changes in manufacturing  
technology and materials used to produce higher intensity products over a large range of the wavelength spectrum have  
changed this. Marl has an approved system of ESD control from goods in, through production and into final packing and  
despatch. Marl recommend all users of LED based products follow the guidelines of BS 100015.  
Power De-Rating  
The forward voltage/ current value of an LED is dependant upon the ambient temperature of the environment in which it is  
operated. Therefore, care must be taken to operate the LED at the correct voltage/ current values, depending upon the  
ambient temperature. Consequently, a recommendation regarding operating voltages and currents is given in order to address  
these temperature effects. This recommendation is termed ‘de-rating’. It is usual for forward voltages and currents to be  
specified for ambient temperature of 25°C. However, because the values of these qualities vary with temperature, please refer  
to the de-rating graphs for correct operation. Marl accept no liability for any product that is operated higher than the stated  
voltage.
