12v AC is equal to 12v DC?
No, 12V AC (alternating current) is not equal to 12V DC (direct current). The key difference between AC and DC is the direction in which the electric current flows. In an AC system, the current changes direction periodically, typically in a sine wave pattern. This is the type of electricity that comes from the outlets in your home.
On the other hand, in a DC system, the current flows in one direction continuously. This is the type of electricity that you might get from batteries or solar panels.
While both 12V AC and 12V DC systems have the same voltage level of 12 volts, they are fundamentally different in terms of how the voltage is delivered and the characteristics of the current flow. It's important to use the appropriate type of current for the specific devices or equipment you are working with to ensure proper operation and safety.

If the bulb shows an input voltage of 12VDC and your caravan or boat battery has an output voltage of 12VDC, but it is still not possible to connect them directly together, a voltage regulator will need to be fitted between them as the voltage from the car or boat is not stable and can sometimes be as high as 14.5V, which can be dangerous for the bulb.
There areWhat do I need to pay attention to the installation of constant current LED driver and mini small spotlight? 2 kinds of constant current LED driver, one is 350mA current output, can only be used for 1W mini spotlight with 350mA. The other one is 700mA current output, which can only be used for 3W mini spotlight.
Each constant current LED driver has a voltage output range, the working voltage of each mini spotlight (1W or 3W) is between 3-3.3V, the working voltage of all the LED mini spotlights must always be within this range, it can't be more than the voltage range, and can't be less than this voltage range.
All small spotlights must be connected in series and then connected to the LED constant current power supply, never in parallel.
Normally the voltage in an RV is unstable and usually fluctuates between 11-14.5V, so when installing 12V LED fixtures, be sure to install a 12V voltage stabilizer or you will burn out the LED lights.
