1. The approved lighting type for KAM access road is 250 watts High Pressure Sodium type and not LED type. Refer to approved project proposal drawing number KA-714490 sht 001.
2. The use of High Pressure Sodium and Metal Halide type of fixtures were the only Saudi Aramco approved fixtures for street lighting and outdoor lighting thru Saudi Aramco Standard SAES P-123 issued Oct. 19, 2008 and modified version issued Feb. 28, 2010 para. 4.2.4. The KPSS lighting design date has been set to 2010 issued Standards contractually.
2. Technically, changes with the fixture type from HPS to LED has significant impact on the electrical loads, SAES P-123 table 4 requires a minimum of 10 lux for the roadways. With a 30 meter spacing of the lighting pole to meet the existing lighting arrangment, a lighting fixture needs at least a minimum of 23,000 lumens to meet the illumination requirements. There is no available LED fixtures that contains such lumens, a maximum LED lumens can give only 16,800 lumens based on model LED Streetlights, LED Street Light Bulbs, LU8 from DMX LED lighting website.
With this LU8 maximum lumens availability, we need to increase the number of poles and decrease the spacing pattern, additional switchracks, LV cables are in need to meet the lux requirements. This changes will have a huge varation order and time impact for the project.
