What does the 830 in the name mean?

It is a color code: 80 for color rendering and 30 for 3000K. This lamp gives warm white light with a color rendering index around 80.

Will it fit my fixture?

Only if your fixture takes a 2GX13 base and a 9-inch circular T5 tube. Check the old lamp's base and diameter before ordering.

No. It is a fluorescent tube and needs a ballast that supports 2GX13 circline lamps.

How does it compare with a plain circline tube?

The tri-phosphor coating gives better brightness and color rendering than basic halophosphate tubes. Output and life still depend on the ballast.

Can I use it in a dimmer?

Only if your ballast and fixture are rated for dimming with this lamp type. Most standard circline ballasts are not.

How should I dispose of it?

As fluorescent waste. It contains mercury, so take it to a local hazardous-waste or bulb recycling point rather than household trash.

Our take on the Bulbrite 520091 - FC9T5/830 Circular T5 Fluorescent Tube Light Bulb

The Bulbrite FC9T5/830 is a circular T5 fluorescent tube with a 2GX13 base, built for fixtures that take a ring-shaped lamp. It uses tri-phosphor coating for strong brightness and color rendering, and the 830 code marks it as a 3000K warm white lamp. It suits ceiling and pendant fixtures in kitchens, offices and shops that were designed around circline tubes. Compared with generic circline lamps, the tri-phosphor coating is its main edge; it is a straight replacement part, not an upgrade to LED.
