Buck converter will power LED's but voltage divider will not....

[QUOTE="Baluncore, post: 6234473, member: 447632"] 50 volts is too high for the majority of buck converters. You must find one that will work safely at higher voltages, or use a pre-regulator to drop the converter input voltage to safe levels. Buck converters can be very efficient. A divider or series resistor to drop voltage before the buck converter will get hot and waste energy. If the resistance is high, insufficient current will reach the converter. With a series resistor, if the LEDs are disconnected, or not turned on, the buck converter will get full voltage. [/QUOTE]
