A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited-quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series.
An LED driver is the power supply for an LED system, much like a ballast is to a fluorescent or HID lighting system, says Al Marble, manager - sales & market development for Philips-Advance Transformer.
Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article. 'LED drivers' are electronic DC power regulators designed specifically for DC LED lighting.R16 LED lights vary in complexity across manufacturers and model designs. The most basic 12V retrofit LED downlight will include the DC LED chips for the light source, and a bridge rectifier composed of diodes to deliver DC to the LEDs from the AC transformer supply.
