- Will this fit my existing circular fixture?
- It fits fixtures that take an 8-inch circular tube with a 22 W rating and a matching 4-pin or 2-pin socket. Check the old tube's pin base and wattage before ordering, since bases differ.
- Is 4100 K warm or cool?
- It is neutral white, cooler than the 2700–3000 K warm tubes common in homes. It reads clean and slightly clinical, which suits kitchens, garages and task lamps.
- Does it work in any fixture?
- No. It needs a ballast made for this tube type. If the fixture's ballast has failed, replacing the tube alone will not light it.
- Should I switch to LED instead?
- If the fixture is in good shape and you want to keep it, this tube is the simple swap. For lower running costs and longer life, an LED circular retrofit is the modern alternative.
- How should I dispose of old tubes?
- Fluorescent tubes contain mercury, so take spent ones to a household hazardous waste site or a retailer that accepts them. Do not put them in regular trash.
