This document provides guidance on selecting an appropriate LED driver by considering several key factors: - Choose between a constant current or constant voltage driver based on the lighting requirements. Consider the output current or voltage and how it meets the light's needs. - Consider the maximum wattage requirement of the light and match it to the driver's output. Also match the driver's input voltage range to the location where the light will be used. - Determine if dimming is needed and if so, what type of dimming compatibility is required. - Check that the driver has the appropriate IP rating for protection against environmental factors like water and dust. FSP offers a wide range of LED drivers for various
