Will this fit my magnifier lamp?

Only if the lamp takes an FC8T9 tube with a 4-pin G10Q base. Check the old bulb's markings or the fixture label before ordering.

Does it need a ballast?

Yes. This is a fluorescent tube and needs the fixture's magnetic or electronic ballast. It is not a plug-and-play LED replacement.

No. Output depends on the ballast, and the tube is not designed for dimming.

What color is the light?

Cool white, around 4100K, similar to a bright office or utility light. It is not a warm white.

Can I use it outdoors?

It is rated for indoor use. Keep it in a dry, enclosed fixture.

Should I switch to an LED circline instead?

If your fixture's ballast is failing or you want lower running costs and longer life, an LED retrofit is the better long-term choice. This tube makes sense when the fixture works and you just need a replacement.
