Review: Rebirth opf my late brother's lighted magnifier - Restored lighted magnifier to full potential. Ideal for hobbyists who need close magnification while working.
Review: Diameter of tube could cause improper fit. - Size variation Order this light to replace a bulb in a craft light that has always been hard to replace. 1st order the bulb was wrong size. Ended up order the same exact part number from same company but different ad. The 2nd bulb fit fine. All part numbers are the same. Difference in size and fit is due to tube diameter that is larger in first order that then causes inside diameter of bulb to be smaller. No big deal, but be aware of potential quality control issues causing the bulb size to be different.

## Questions & Answers

**Q: You say it won't fit Conair mirrors due ro pin placement, but i thought the pins swiveled somewhat?**
A: I used it on the conair.  You have to open the old Conair, snip the cable holder and move the plug to one side so the cable stretches.  The plug fits.  You might see a little of the cable peaking out of one edge of the mirror, but big deal.

**Q: Does this actually measure 5.25"? the bulb i need to replace has the same t4 12w 6400k number, but measures 4.75" diameter.**
A: The bulb measures 5 1/4” outside diameter. It was slightly larger than the original bulb but still fit in the lamp.

**Q: Will this fit the aven 26501-siv light?**
A: I have a different light. It fit mine but don’t know if it would fit yours. Just measure the old bulb. And look at the prongs to make sure they match.

**Q: Es de 4 pins?**
A: De 4 pins

### ⭐⭐⭐⭐ Works well but ensure you have the right size
*by G***. on June 28, 2021*

I bought this as a replacement for the original fixture but did not notice that there is a slight size difference. Ensure the circumference is correct before buying. I made it fit by jerry-rigging it. Wasn't mfrs fault that I didn't measure and did not want to return it as a result. Works well after retrofitting it into the mirror fixture.
