## Questions & Answers

**Q: Replacing traditional 20 watt halogen bulb. Any Match up problems?**
A: As long as the base connectors are the same as the socket they will work.  You should not replace existing bulbs with higher wattage because they do get hot so I dont use them in items that might be flammable like Christmas decorations

**Q: Is it dc or ac voltage?**
A: Either works fine, provided the power supply to the bulb provides regulated 12VAC or 12VDC with an ampacity of ~1A or more. The DC parity doesn't matter because the MR11 pin base is bilaterally symmetric. So just plug and play.

**Q: will they fit g4 socket ?**
A: It should >>> "GU4 Bi-Pin Base" is a 2-pin male push-in base. I measure the skinny pins on these MR11 Bulbs at 4mm apart and 6mm long.

**Q: Do these work for a fiber optic Christmas tree?**
A: Not sure what you mean. These bulbs are about a little over an inch and a half across. Cant imagine they would work on a christmas tree.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Don't throw away your vintage fiber optics!
*by K***C on November 10, 2022*

Don't throw out your old fiber optics before checking to see if it's just the light bulb. If the color wheel motor is blown, fixing them is a little more complicated, but if it's just the light bulb? Pie e of cake! Just buy these awesome bulbs. Unscrew the base of your fiber optic base, pull out the blown bulb and pop in the new one. They pop in and out easily! I just brought three of my favorite holiday fiber optics pieces back to life (see attatched photos!) Plus I have plenty of bulbs left to fix any others that may pop up (or out) thanks to the great value of these awesome bulbs the Holidays will be bright this year! Well.. Or colorful at least! Thank you to the seller For the lightening fast delivery and to Amazon for having almost everything I need in my life! If only you sold high rated husbands! HA HA! Wait... 🤔 Do you?! 😂 Lol!

### ⭐⭐⭐⭐⭐ Does what a light bulb should do
*by E***. on June 22, 2025*

I have used exactly ONE of these. It went into a very cool Halloween decoration, which had a burned out bulb. The bulb we purchased fit as expected, and worked as expected. At our current rate of use, I figure that we have enough bulbs to last for at least the next 150 years, at which time these will likely cost about $2,000 each, so I'm looking at this as a long-term investment.

### ⭐⭐⭐⭐⭐ work well, fast shipping fair price.
*by B***N on July 9, 2025*

work well, fast shipping fair price.
