[QUOTE="Bruspark, post: 527344, member: 20106"] The one that blew up was a 200mA DC constant current driver, that can supply that current over an output voltage in the range of 38 to 48 volts. (Many led lamps see their voltage change with temperature or colour switching so constant voltage is no good) It’s left unclear how many watts it’s rated to supply but it will be 10-15 most likely. The notation on the + - output pins is a little weird but if there’s no colour or dimmer switch on the driver it’s probably just simple DC (vs reversible pulsed etc a la Xmas lights and ropes) You may find one on the web that does the same and it may even work. Depends how much you value the lamp and your time … [/QUOTE]
