Can I use 12V transformer for LED?

12 Volt LED light bulbs can either be powered directly from a 12V DC source (such as a battery bank) or via a transformer which turns mains electricity (240VAC in the UK) into 12 Volts DC. Existing transformers typically used with halogen spotlights can usually be used however there is one problem.

What is the difference between an LED driver and a transformer?

LED drivers and electronic transformers for retrofit LED lighting are not interchangeable. They differ in output and load compatibility i.e. which LED lights they will work with. The fundamental difference between the two is that LED drivers output DC while electronic halogen transformers output 12VAC.

How do I choose an LED transformer?

5 Important Factors When Buying LED Drivers

  1. Output Voltage / Current. First, consider the voltage requirements of your light. …
  2. Input Voltage / Current. Next, consider the voltage supply of the location you’ll be using your light. …
  3. Max Wattage. Lastly, consider the wattage requirements of your light. …
  4. IP Ratings.

What size transformer do I need for LED lights?

Transformers generally range from 150- to 900-watt capacity. Matching the size of the transformer to the lighting design is important for efficient operation and function of the system. House current, 120 volts, is reduced by a transformer to 12 to 20 volts, the current needed to operate low-voltage landscaping lights.

Can you use a halogen transformer for LED?

Lower Light Output: It sounds counterintuitive, but the higher voltage from a halogen transformer can actually damage the LED and lead to lower light output. … LEDs run on DC power, not AC. Using them in an AC circuit will lead to voltage fluctuations that will cause the bulbs to flicker, buzz, or dim erratically.

Is an LED driver just a transformer?

AC LED drivers are actually no-minimum load transformers, meaning they could technically operate low-voltage halogen or incandescent bulbs as well. LEDs, however, cannot operate with conventional transformers because conventional transformers were not made to detect the low wattage of LEDs.

What voltage is needed for LED?

LEDs often require a certain amount of volts, depending on the type and color of the LED. Most experts recommend 2-3 volts for LEDs.

Can I use an LED driver as a power supply?

converters provide an output that is regulated to provide a “constant-voltage.” However, LEDs work most efficiently and safest with a “constant-current” drive. … Today, the terms “LED driver” and “LED power supply” are used interchangeably.
