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. … Buzzing, Dimming, or Flickering Lights: This is a common problem when LED downlights are used without an LED driver. LEDs run on DC power, not AC.
Do I need a special transformer for LED lights?
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.
What transformer do I need for LED lights?
All LED bulbs require a ‘driver’ (a special type of transformer) to work properly. Mains voltage LEDs (such as GU10 and B22 bulbs) have the driver built in to the bulb. MR16 and other 12V bulbs use an external driver.
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.
Can I replace 12V halogen with LED?
Yes, in many cases, you can simply replace your bulbs separately, one by one. Furthermore, LEDs can handle all hues of white light, so the warm yellowish light of halogen bulbs is perfectly within reach! …
Can I use 12V AC instead of 12V DC?
As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.
Can I replace 50W halogen with LED?
If you’re replacing low voltage MR16 50W halogens that have low voltage 12V transformers, the first and obvious option is to replace it with something like an MR16 LED. These retrofit lamps should operate from your existing transformers. … This often results in you having to replace your transformers.
Do 12V LEDs need drivers?
Because LEDs require a constant DC of 12v or 24v, LED drivers are required in all LED systems (except those which are specifically developed to be controlled by mains voltage power supplies such as mains voltage tape or LED bulbs).
Can I replace 12V G4 halogen with LED?
#3 The compatibility
While replacing 12v halogen lights with G4 LED 12v, it is important to check the compatibility of the G4 LED lights with the lighting fixtures. As mentioned before, most of the G4 LEDs operate on DC voltage, so they will need a different power supply or transformer to operate.
Does each downlight need a transformer?
IC Rated modular downlights do not require a transformer/driver as they are connected directly to a power supply. Therefore replacing halogen downlights with IC Rated modular downlights will save additional energy that would otherwise be consumed in the transformer/driver (i.e. between 1 and 15 watts each).

What is 20W halogen equivalent to in LED?
20w LED floodlights are equivalent to 200w halogen floodlights with an increased lumen output of 1,800. 30w LED floodlights are equivalent to 300w halogen floodlights with an increased lumen output of 2,700.
How much does it cost to replace halogen downlights with LED lights?
Some electricians may charge as much as $100 per downlight, but expect to be charged around $60 – $75 per point for installing LED downlights.
