## Questions & Answers

**Q: will these bulbs work in virilux lamps?**
A: NO. Neither of the 2 Sunlite bulbs I received would work in any of my lamps that use Verilux CFML27VLX bulbs. The only difference I can see it that the Sunlite bulb's pins are too short, shorter than the Verilux.  I returned them.  There is a photo of showing the pins on both the Sunlite and Verilux bulbs in my review. I don't know how to put the photo here.

**Q: My lamps labels read “ 65 watt , 120v , type fml “ will this bulb work?  thank you**
A: No it will not.  This is a 27 watt bulb.

**Q: Do these work with touch lamps?**
A: If the lamps have the correct outlets I do not see why they would not work.  Touch or switch the electricity is the same.

**Q: Do you have lamps that are longer than 6"?  My reading lamp has a clamp that is somewhere around 8" from the lamp base.**
A: No. These FML style bulbs are all a standard length.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Office light replacement bulb
*by K***H on January 23, 2026*

Arrived on time, works as described, good quality product

### ⭐⭐⭐⭐⭐ Quality bulb, affordable.
*by B***M on December 14, 2025*

These are very bright.

### ⭐⭐⭐⭐⭐ Good (but not for Verilux lamps)
*by S***T on January 17, 2026*

This works fine in my non-Verilux lamp.. Note that these dont fit a Verilux lamp which has a slightly different (but important) base. Check the 2 side tracks at the bottom-for verilux they're longer but with a gap at very bottom.
