Yes, most MR16 LED bulbs require a transformer because they operate on low voltage (typically 12V) rather than standard household voltage. It’s important to ensure the transformer is LED-compatible, since older halogen transformers can cause flickering or may fail to power the bulb correctly. If your existing setup isn’t compatible, replacing it with a dedicated LED driver or electronic transformer will provide stable performance and extend the bulb’s lifespan.
