Why do I need a 12V LED-compatible transformer for some LED bulbs?

You may only need a transformer if you are buying 12V bulbs such as MR16, G4 and MR11.

Standard electronic transformers can cause certain types of LED bulbs to flicker, resulting in permanent long-term damage to the LED bulb itself. This problem is most evident in 12V MR16 LED bulbs where a standard transformer does not provide a smooth flow of current, causing flickering problems. To avoid damaging your new LED bulbs it is always best to use LED drivers/transformers.
