All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V).26 Sept 2019
How do I know if my transformer is LED compatible?
- It Has a High IP Rating.
- The Output Voltage Matches That of Your LED Bulbs.
- Its Output Current Is Higher Than That of Your LEDs.
- Its Power Factor Is Above 0.9.
- Its Output Wattage Equal or Higher Than That of Your LEDs.
- It Has Dimming Ability.
- It's Compact in Size.
Can I use 12V transformer for LED?
FAQ - 12V Transformers and LED Compatibility. Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article. 'LED drivers' are electronic DC power regulators designed specifically for DC LED lighting.
Can you power an LED with 12V?
Connect the positive terminal of the 12 volt power supply to one side of the resistor. Connect the other side of the resistor to the anode of the LED. Check the LED data sheet to identify the anode and cathode. The cathode is commonly the shorter lead and located nearest any flat side of the LED.24 Apr 2017
Can I use a 12V halogen transformer for LED lights?
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.
Can you use electronic transformer for LED lights?
An electronic transformer can typically handle the same size LED lighting applications as LED drivers. In addition, an electronic transformer may be used when a combination of LED lighting and halogen lighting applications exists.
How do I choose a LED transformer?
- Output Voltage / Current. First, consider the voltage requirements of your light.
- Input Voltage / Current. Next, consider the voltage supply of the location you'll be using your light.
- Max Wattage. Lastly, consider the wattage requirements of your light.
- IP Ratings.
