I have an LED driver:
But I cannot understand the 12-40V @ 350mA and what I should be looking for to replace it with. The light gives no indication of voltage or draw so I'm trying to match this power supply and have no clue where to find one or do the math to figure out what a compatible driver would be.
Any help would be appreciated I'm in the US at 120V household.
As @digitalninja mentions, this is a constant current led driver. Unlike a variable current/constant voltage power supply, that attempts to keep the same voltage output regardless of the current pulled, a constant current supply will attempt to keep the same current, by varying the voltage.
It will, given a load like an led bulb, change the voltage until the current becomes 350mA. That could be a 24V 350mA led bulb/strip, or a 12V 350mA led bulb/strip, or whatever.
As such, you are looking for bulb that states it is that current draw within that voltage range.
