## Questions & Answers

**Q: The MR16 bulbs in my home are 12V. Is this one also 12V?**
A: This bulb is rated at 12 volts and must not be used directly in a 220–240-volt circuit; it must therefore be used strictly with a 12-volt supply to prevent the bulb from burning out or flickering due to an incorrect voltage.

**Q: Can I continue to use my current halogen lamp transformer with this bulb?**
A: Older dimmer made for halogen have a high minimum 40–60W load; single low-watt LED bulbs often can’t meet that threshold, which may trigger flicker,hum or unstable brightness. We recommend upgrading to an LED-specific dimmer for perfect performance.

**Q: Is this the standard size? I’ve bought others before that were a bit too big, so they wouldn’t fit into the frame.**
A: This is a standard MR16 bulb, designed to universal specifications and compatible with almost all MR16 pin-type sockets on the market, so you can purchase it with confidence.

**Q: Compared to standard MR16 LED bulbs, how much energy do GY Grade C LED bulbs save?**
A: The GY MR16 LED bulb is rated at energy efficiency class C, which is far superior to conventional E/F-rated energy-saving bulbs, and can reduce lighting costs by up to 90.5%.
