- friend_and_foe 3y ago12v is perfectly reasonable for lighting, fans and water pumps.
- amluto 3y ago12V is reasonable for lighting on a small scale. It’s not really fit for purpose for lighting on a house or garden scale. (It’s not even really awesome on a small scale - nice LEDs chips and board vary between 4 and 50V or so and should be driven at constant current. With a 12V supply, this requires a buck-boost converter. With a 48V supply, most bases are covered with a simpler buck converter.) And 12V in a vehicle makes little sense if the vehicle’s battery operates at 24V or 48V — it requires DC/DC conversion for no real benefit.
