LED versus Fluorescent Lighting: Lighting Needs Vary by Application, So How Does Led Lighting Stack Up Financially against Fluorescent Lighting Options in an Educational Setting?Charest, Adrian
such as voltage sources/ballast resistors and linear regulators, fall short as the complexity and input power requirements of LED-based lighting sources increase. Thus a more sophisticated switch-mode LED driver is required. So
Multiple lumen packages up to 18,000 in 2x4 and 9,000 in 2x2 Up to 140LPW for maximum energy savings versus fluorescent troffers Correlated Color Temperatures 3000K, 3500K, 4000K and 5000K at 80 CRI Standard 0-10V continuous dimming driver ...
In part one of this series, we looked at the basics of LED lighting sources and their driving requirements. In part 2, we discussed why a constant-current buck converter should be your first preference when it comes to switch-mode LED drivers. In this third installment, we investigate larger...
