Light source shall be high luminous, long life typical 50,000 Hrs. type, 0.5 Watts LED's assembled on aluminum PCB. The thickness of the aluminium PCB should be 2mm in order to ensure proper heat dissipation. These aluminium PCB’s should be placed not more than 160mm apart across the length of the board in order to ensure uniform distribution of light across the board. Each board having length from 800mm up to 3000mm should be illuminated by a single converter & by using single isolating transformer of suitable wattage in order to save the capital cost of multiple isolating transformers. Signage shall be suitable for operation on series circuit at variable current from 2.8Amp - 6.6Amp and will give constant brightness for all current variation. All the signage shall have letters and symbols made by computerized cutting of vinyl and pasting on the polycarbonate sheet from inside/outside of the sign face of required color as per ICAO.
