The good location for Led Public lighting(Classic) https://www.classicledlight.com/ testing is a low-flow residential area with an existing 70 W or 100 W HPS cobra head, consistent single-sided pole spacing and minimal trees. Once this area has been determined, use the exact street width, pole position and mounting height to invite selected LED manufacturers to use their product's IES file for test installation (1,0 optical loss factor for verification) for lighting calculations. Suggested products should meet lighting design standards or your existing HID lighting levels. It is recommended to purchase at least four luminaires from each manufacturer or supplier. These samples should be visually evaluated prior to installation. Packaging should pay special attention. If the box is insufficient, the luminaire may be damaged during shipment. However, over-packaging can greatly slow down the installation because additional travel is required to pick up additional fixtures and return to the carton material for recycling. After inspecting the samples, replace four adjacent HID fixtures with the four purchased products and repeat for all manufacturers at the selected test location. If possible, test the actual power consumption (system power) of each unit before or during installation. Click public lighting https://www.classicledlight.com/ to learn about more information.
